How To Fix IDOC_ADAPTER605 - Field SNDPOR=&1 does not equal 'SAP' + System ID

SAP Error Message - Details

• Message type: E = Error

• Message class: IDOC_ADAPTER - Messages for the IDoc Adapter

• Message number: 605

• Message text: Field SNDPOR=&1 does not equal 'SAP' + System ID

What causes this issue?

The field SNDPOR= &1 does not start with 'SAP'.

System Response

The field SNDPOR with the value &1 in the IDoc control record does not
start with 'SAP'. Therefore, it is not possible to determine a business
system as the sender.
Example: You can determine the system ID 'ALR' from SNDPOR = SAPALR.

How to fix this error?

Only send IDocs that have the value 'SAP' + system ID (3 digit) as the
sender port in the control record to the IDoc adapter.

Procedure for System Administrators

• What is the cause and solution for SAP error message IDOC_ADAPTER605 - Field SNDPOR=&1 does not equal 'SAP' + System ID ?

  The SAP error message IDOC_ADAPTER605 indicates that there is a mismatch between the sender port (SNDPOR) of an IDoc and the expected value, which should be 'SAP' followed by the system ID. This error typically occurs in scenarios involving IDoc processing, especially when IDocs are being sent or received between different systems.
  Cause:
  
  Incorrect Sender Port Configuration: The sender port (SNDPOR) in the IDoc does not match the expected format. The expected format is 'SAP' followed by the system ID (e.g., 'SAPXYZ' where XYZ is the system ID).
  IDoc Configuration Issues: The IDoc configuration in the SAP system may not be set up correctly, leading to discrepancies in the sender information.
  Middleware Issues: If you are using middleware (like SAP PI/PO), there may be issues in the mapping or configuration that lead to incorrect sender information being sent.
  Manual Changes: If the IDoc was manually created or modified, it may have incorrect sender information.
  
  Solution:
  
  
  Check Sender Port Configuration:
  
  Verify the configuration of the sender port in the SAP system. Ensure that the port is correctly defined and that it matches the expected format.
  Go to transaction WE21 (IDoc Ports) and check the configuration of the port being used.
  
  
  
  Review IDoc Settings:
  
  Check the IDoc type and its associated settings to ensure that they are correctly configured.
  Use transaction WE30 to review the IDoc type and ensure that the sender information is correctly defined.
  
  
  
  Check System ID:
  
  Ensure that the system ID configured in the IDoc matches the actual system ID of the SAP system sending the IDoc.
  You can find the system ID in transaction SM51 (List of SAP Systems).
  
  
  
  Middleware Configuration:
  
  If using middleware, check the configuration and mappings to ensure that the sender information is being passed correctly.
  Review any transformation or mapping logic that might alter the sender information.
  
  
  
  Testing:
  
  After making the necessary changes, test the IDoc processing again to ensure that the error is resolved.
  
  
  
  Related Information:
  
  IDoc Monitoring: Use transaction WE02 or WE05 to monitor IDocs and check for any other related errors or issues.
  SAP Notes: Check for any relevant SAP Notes that might address this specific error or provide additional troubleshooting steps.
  Documentation: Review SAP documentation on IDoc processing and configuration for more detailed guidance on setting up IDocs correctly.
  
  By following these steps, you should be able to identify and resolve the issue causing the IDOC_ADAPTER605 error.
