• What is the cause and solution for SAP error message B1049 - More than one IDoc passed ?

  The SAP error message B1049 ("More than one IDoc passed") typically occurs when a process is expecting a single IDoc (Intermediate Document) but receives multiple IDocs instead. This can happen in various scenarios, such as during the processing of inbound IDocs or when sending IDocs to an external system.
  Cause:
  
  Multiple IDocs Sent: The most common cause is that the system is configured to send or process multiple IDocs at once, but the receiving function module or process is designed to handle only one IDoc at a time.
  Incorrect Configuration: There may be a configuration issue in the IDoc processing settings, such as in the partner profile or message type settings.
  Batch Processing: If IDocs are being processed in a batch and the batch size exceeds the expected limit, this error can occur.
  Custom Code: If there is custom code involved in processing IDocs, it may not be handling multiple IDocs correctly.
  
  Solution:
  
  Check IDoc Processing Logic: Review the function module or program that is processing the IDocs to ensure it is designed to handle multiple IDocs if that is the intended behavior. If it should only handle one, ensure that the calling process is only sending one IDoc at a time.
  Adjust Partner Profile: If the issue is related to the partner profile, check the settings in transaction WE20. Ensure that the settings for the message type and IDoc type are correct and that they match the expected processing logic.
  Batch Size Configuration: If IDocs are being processed in batches, check the configuration for batch size limits. Adjust the batch size to ensure that only one IDoc is processed at a time if that is required.
  Error Handling in Custom Code: If there is custom code involved, ensure that it includes proper error handling and logic to manage multiple IDocs if necessary.
  Testing: After making changes, test the IDoc processing with a single IDoc to confirm that the error no longer occurs.
  
  Related Information:
  
  Transaction Codes: Use transaction codes like WE02 (Display IDoc), WE19 (Test IDoc), and WE20 (Partner Profiles) to analyze and troubleshoot IDoc issues.
  IDoc Types and Message Types: Familiarize yourself with the specific IDoc types and message types involved in the process to understand their configurations and expected behaviors.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on IDoc processing.
  
  By following these steps, you should be able to identify the cause of the B1049 error and implement a solution to resolve it.
