UC090 - Details

• The SAP error message UC090 indicates that there is a mismatch between the logical sender structure and the physical sender structure in the context of a process that involves sending data, typically in the context of IDocs or other data transfer mechanisms. This error usually arises when the system expects a certain field to be present in the physical structure but it is only defined in the logical structure.
  
  Cause:
  
  Mismatch in Structures: The logical sender structure (which defines the data format expected by the receiving system) includes a field that is not present in the physical sender structure (the actual data being sent).
  
  Configuration Issues: There may be a configuration issue where the sender system's data structure has not been updated to match the logical structure.
  Changes in Data Model: If there have been recent changes to the data model (e.g., adding or removing fields), the physical structure may not have been updated
