Send an IDoc to SAP

This example shows you how to create a Mule app that sends an IDoc to SAP. The following screenshot shows the Studio flow for this example:

Studio flow for sending an IDoc to SAP

Configure HTTP Listener

Configure HTTP Listener to initiate a Mule flow when a call is made to the /sendIDoc path on localhost port 8081:

  1. In Anypoint Studio, create a new Mule project.

  2. From the Mule Palette view, drag the HTTP > Listener source to the canvas.

  3. Configure the global element using the default values.

  4. In the Listener properties tab, set the path to /sendIDoc.

Add the Transform Message Component

Configure the Transform Message component to convert the IDoc input to XML:

  1. From the Mule Palette view, select Core and drag the Transform Message component next to the Listener source.

  2. After the metadata is retrieved, overlay the text in the Output section of the Transform Message component with the following text:

    %dw 2.0

Add the Send IDoc Operation

The Send IDoc operation sends an IDoc to SAP over a remote function call (RFC):

  1. From the Mule Palette view, select SAP and drag the Send IDoc operation next to the Transform Message component.

  2. Create a global element named SAP_Outbound and specify the connection information.

  3. Click Test Connection to confirm that Mule runtime engine can connect with the SAP instance.

    • If the connection is successful, save the configuration.

    • Otherwise, review and correct any invalid parameters, and test again.

  4. Configure the Send IDoc properties with the following values:

    Field Value

    IDoc Name

    MATMAS01

    Content

    #[payload]

Add the Logger Component

The Logger component displays the connector payload in the Studio console.

  1. From the Mule Palette view, select Core and drag Logger next to the Send IDoc operation.

  2. Click File > Save to save the app.

Run the App

To run the Mule app:

  1. Click Run > Run as > Mule Application.

  2. From a web browser, test the application by entering an employee’s internal ID, first name, and last name as query parameters for the following URL:

    http://localhost:8081/sendIDoc

    Mule sends the IDoc to SAP.

XML for Sending an IDoc to SAP

Paste this code into a new Mule app in Studio to quickly load the flow for the sending an IDoc example. Change the values to reflect your environment.

Receive an Incoming IDoc Request

This example shows you how to create a Mule app that waits for incoming IDoc requests from an external SAP system. In this example, the app acts like an RFC server and registers itself as an SAP gateway. When the app receives an IDoc request, it uses a remote function (RFC) call to ask SAP to create the IDoc. Then it logs the IDoc contents to the Studio console.

The following screenshot shows the Studio flows for this example:

Studio flow for retrieving an IDoc

Configure the First Flow

The first flow uses a BAPI function to send IDoc requests to an external SAP system. To configure this flow:

  1. In Anypoint Studio, create a new Mule project.

  2. From the Mule Palette view, select HTTP and drag the Listener source to the canvas.

  3. Configure the global element using the default values.

  4. In the Listener properties tab, set the path to /trigger.

  5. Drag a Transform Message component next to Listener.

    The content of this message is the payload of the BAPI function that receives the IDoc requests.

  6. In the Output section of the Transform Message component, overlay the brackets with this text:

    %dw 2.0
output application/xml
---
{
	ZMMFM_TRIGGER_IDOC_MATMAS: {
		"import": {
	IV_MTYP: "MATMAS"
,
IV_OBJ: "23"
,
IV_SYS: "MULE11_LS"
}
,
export: {
	EV_RET: "0"
},export: {
	EV_OBJ: "0000000003526552"
},export: null,changing: null,
tables: {
	T_MSG: null
},
	}
}

  7. From the Mule Palette view, select SAP and Drag the Synchronous Remote Function Call operation next to the Transform Message component.

  8. Create a global element named SAP_Config and specify the connection information.

  9. Click Test Connection to confirm that Mule runtime engine can connect with the SAP instance.

Configure the Second Flow

The second flow logs the contents of each new IDoc request to the Studio console. To configure this flow:

  1. From the Mule Palette view, select SAP and drag the Document listener source to the canvas.

  2. Create a new global element for the source and specify the required information.

    Configure the Document listener properties with the following values:

    Field Value

    Gateway host

    Host running the gateway server

    Gateway service

    3200

    Program id

    MULE01_PID

    Connection count

    1

    Idoc type filter regex

    MATMAS01

    The Gateway host, Gateway service, and Program id must be retrieved from the customer’s SAP team.

    Anything that relates to the SAP instance, such as configurations or credentials, must be retrieved from the customer’s SAP team.

  3. From the Mule Palette view, select Core and drag a Logger component next to Document listener on the canvas.

  4. Click File > Save to save the app.

Run the App

To run the Mule app:

  1. Click Run > Run as > Mule Application.

  2. From a web browser, test the application by entering the following URL:

    http://localhost:8081/trigger

This example performs two calls on standard BAPIs that handle bank records and manages those transactions.

The following screenshots show the Studio flows for this example:

Studio flow for the first flow of Managing Transactions
Studio flow for the second flow of Managing Transactions
Studio flow for the third flow of Managing Transactions

Configure the First Flow

The first flow retrieves a list of available banks in the United States, filters the first result, and fetches information about the bank. Transactions are not necessary for queries to SAP. To configure this flow:

  1. In Anypoint Studio, create a new Mule project.

  2. From the Mule Palette view, select HTTP and drag the Listener source to the canvas.

  3. Configure the global element using the default values.

  4. In the Listener properties tab, set the path to /sync-rfc.

  5. Drag a Transform Message component next to Listener.

    The content of this message filters the banks by country.

  6. In the Output section of the Transform Message component, overlay the brackets with this text:

    %dw 2.0
output application/xml
---
{
	BAPI_BANK_GETLIST: {
		"import": {
			BANK_CTRY: "US",
			MAX_ROWS: 0
		}
	}
}

  7. From the Mule Palette view, select SAP and drag the Synchronous Remote Function Call operation next to the Transform Message component.

  8. Create a global element named SAP_Config and specify the connection information.

  9. Click Test Connection to confirm that Mule runtime engine can connect with the SAP instance.

  10. Enter BAPI_BANK_GETLIST for the Function Name and payload for the Content.

  11. Drag another Transform Message component next to Synchronous Remote Function Call.

    The content of this message filters the first result.

  12. In the Output section of the Transform Message component, overlay the brackets with this text:

    %dw 2.0
output application/xml
---
{
	BAPI_BANK_GETDETAIL: {
		"import" : {
			BANKCOUNTRY: payload.BAPI_BANK_GETLIST.tables.BANK_LIST.*row[0].BANK_CTRY,
			BANKKEY: payload.BAPI_BANK_GETLIST.tables.BANK_LIST.*row[0].BANK_KEY
		}
	}
}

  13. From the Mule Palette view, select SAP and drag another Synchronous Remote Function Call operation next to the Transform Message component.

  14. Create a global element named SAP_Config and specify the connection information.

  15. Click Test Connection to confirm that Mule runtime engine can connect with the SAP instance.

  16. Enter "BAPI_BANK_GETDETAIL" for the Function Name and payload for the Content.

  17. From the Mule Palette view, select Core and drag a Logger component next to Synchronous Remote Function Call.

Configure the Second Flow

The second flow creates a sales order from the data. You must add try to the BAPI call to create a transaction, otherwise the change does not impact SAP. To configure this flow:

  1. From the Mule Palette view, select HTTP and drag the Listener source to the canvas.

  2. Configure the global element using the default values.

  3. In the Listener properties tab, set the path to /sync-mule-transaction.

---
{
	BAPI_SALESORDER_CREATEFROMDAT2: {
		"import": {
			ORDER_HEADER_IN: {
				DOC_TYPE: "TA",
				SALES_ORG: "3000",
				DISTR_CHAN: "10",
				DIVISION: "00"
			},
			ORDER_HEADER_INX: {
				DOC_TYPE: "X",
				SALES_ORG: "X",
				DISTR_CHAN: "X",
				DIVISION: "X"
			}
		},
		tables: {
			ORDER_ITEMS_IN: {
				row: {
					ITM_NUMBER: "000010",
					MATERIAL: "000000000050066128" as Number as String {format: "000000000000000000"},

				row: {
					ITM_NUMBER: "000010",
					SCHED_LINE: "0001",
					REQ_QTY: "X"
				}
			}
		}
	}
}

  6. From the Mule Palette view, select SAP and drag the Synchronous Remote Function Call operation next to the Transform Message component.

  7. Create a global element named SAP_Config and specify the connection information.

  8. Click Test Connection to confirm that Mule runtime engine can connect with the SAP instance.

  9. Enter BAPI_SALESORDER_CREATEFROMDAT2 for the Function Name and payload for the Content.

  10. From the Mule Palette view, select Core and drag On Error Continue under Synchronous Remote Function Call.

  11. From the Mule Palette view, select Core and drag a Logger component into On Error Continue.

  12. From the Mule Palette view, select Core and drag another Logger component next to Synchronous Remote Function Call.

  13. Enter payload.BAPI_SALESORDER_CREATEFROMDAT2.export.SALESDOCUMENT for the Message.

Configure the Third Flow

The third flow creates a transaction ID and gets a list. Asynchronous calls do not expect a response and require a different way of managing the transaction. Use specific operations to manage transactions of asynchronous calls. To configure this flow:

  1. From the Mule Palette view, select HTTP and drag the Listener source to the canvas.

  2. Configure the global element using the default values.

  3. In the Listener properties tab, set the path to /async-rfc.

Configure Multiple Gateways

This example shows you how to create a Mule app that configures a message server with multiple gateway connections to distribute the load and improve performance, instead of a single gateway connection.

The following screenshot shows the Studio flows for this example:

Studio flows for configuring a message server with multiple gateways

Configure the First Flow

The first flow passes the message server to the Document listener source. To configure this flow:

  1. In Anypoint Studio, create a new Mule project.

  2. From the Mule Palette view, select SAP and drag the Document listener source to the canvas.

  3. Configure the global element for the Document listener source and fill in the required fields.

  4. In the Document listener properties tab, configure the following fields:

    Field Value

    Gateway host

    54.160.77.19

    Gateway service

    3300

    Program id

    MULE11_IDOC_PID

    Connection count

    1

  5. From the Mule Palette view, select Core and drag a Logger component next to Document listener on the canvas.

Configure the Second Flow

The second flow triggers the first individual gateway. To configure this flow:

  1. From the Mule Palette view, drag the HTTP > Listener source to the canvas.

  2. Configure the global element using the default values.

  3. In the Listener properties tab, set the path to /c.

  4. From the Mule Palette view, select Core and drag the Transform Message component next to the Listener source.

  5. In the Output section of the Transform Message component, overlay the brackets with this text:

    %dw 2.0
output application/xml
---
{
  ZMMFM_TRIGGER_IDOC_MATMAS: {
    "import": {
  IV_MTYP: "MATMAS"
,
IV_OBJ: "23"
,
IV_SYS: "MULE11_LS"
}
,
export: {
  EV_RET: "0"
},export: {
  EV_OBJ: "0000000003526552"
},export: null,changing: null,
tables: {
  T_MSG: null
},
  }
}

  6. From the Mule Palette view, select SAP and drag the Synchronous Remote Function Call operation to the canvas.

  7. Configure the global element for the Synchronous Remote Function Call operation and fill in the required fields.

  8. In the Synchronous Remote Function Call properties tab, configure the following fields:

    Field Value

    Function Name

    "ZMMFM_TRIGGER_IDOC_MATMAS"

    Content

    payload

  9. From the Mule Palette view, select Core and drag the Transform Message component next to the Synchronous Remote Function Call operation.

  10. In the Output section of the Transform Message component, overlay the brackets with this text:

    %dw 2.0
output application/json
---
payload

Configure the Third Flow

The third flow triggers the second individual gateway. To configure this flow:

  1. From the Mule Palette view, drag the HTTP > Listener source to the canvas.

  2. Configure the global element using the default values.

  3. In the Listener properties tab, set the path to /d.

  4. From the Mule Palette view, select Core and drag the Transform Message component next to the Listener source.

  5. In the Output section of the Transform Message component, overlay the brackets with this text:

    %dw 2.0
output application/xml
---
{
  ZMMFM_TRIGGER_IDOC_MATMAS: {
    "import": {
  IV_MTYP: "MATMAS"
,
IV_OBJ: "23"
,
IV_SYS: "MULE11_LS"
}
,
export: {
  EV_RET: "0"
},export: {
  EV_OBJ: "0000000003526552"
},export: null,changing: null,
tables: {
  T_MSG: null
},
  }
}

  6. From the Mule Palette view, select SAP and drag the Synchronous Remote Function Call operation to the canvas.

  7. Configure the global element for the Synchronous Remote Function Call operation and fill in the required fields.

  8. In the Synchronous Remote Function Call properties tab, configure the following fields:

    Field Value

    Function Name

    "ZMMFM_TRIGGER_IDOC_MATMAS"

    Content

    payload

  9. From the Mule Palette view, select Core and drag the Transform Message component next to the Synchronous Remote Function Call operation.

  10. In the Output section of the Transform Message component, overlay the brackets with this text:

    %dw 2.0
output application/json
---
payload
