MDMXFW001 - Details

• The SAP error message MDMXFW001: Only one IDoc can be updated at a time typically occurs when there is an attempt to process multiple IDocs simultaneously in a context where only one IDoc can be handled at a time. This is often seen in scenarios involving IDoc processing in the SAP Master Data Management (MDM) or when using IDocs for data transfer.
  Causes:
  
  Concurrent Processing: The system is trying to process multiple IDocs at the same time, which is not allowed in the current configuration or context.
  Locking Mechanism: The IDoc processing might be locked due to another process that is currently handling an IDoc, leading to this error when a second IDoc is attempted to be processed.
  
  Configuration Issues: There may be configuration settings in the IDoc processing that restrict the handling of multiple IDocs.
  
  Solutions:
  
  Sequential Processing: Ensure that IDocs are processed one at a time. This can be done by implementing a queue
