`Unrecognized partner` transaction reported

You might occasionally see tracking information such as this in the Activity section of Anypoint Partner Manager:

<identifier> from Unrecognized partner
<date> control #
Partner not found for <identifier> with <value>

Causes

This information appears in the Activity section when one of the following occurs:

Partner Manager cannot identify the sender of the transmission either because the partner is not configured in Partner Manager, or because the identifier associated with the partner is not configured.
Partner Manager cannot identify the receiver for the transmission because the identifier associated with the receiver is not configured.
Partner Manager cannot identify both the sender and the receiver of this transmission.

Verify partner and host identifiers.

Verify that your partner has the appropriate identifiers configured as needed to support the transmission.

From within your Anypoint Partner Manager, Sandbox or Production environment select Partners <name of your specific partner related to this transmission>.

If the desired partner identifier is not present, click New and select an identifier type from the Type list to uniquely identify your partner.
Provide a value for your identifier (and a qualifier for X12-ISA) and click Create identifier to save your changes. See X12 - ISA Identifier Values for more information about X12-ISA settings.

Verify that your organization (the host) has the appropriate identifiers configured as needed to support the transmission.

From within your Anypoint Partner Manager, Sandbox or Production environment select Partners <name of your organizations / sub-organizations related to this transmission>.
Within the Host’s profile page, scroll to the Identifiers section and verify that the identifier you are looking for is present in the table.
