• What is the cause and solution for SAP error message /IWBEP/SBOD202 - Conversion error possible; ABAP to EDM and EDM to ABAP ?

  The SAP error message /IWBEP/SBOD202 indicates a conversion error that can occur when there is an issue with the data transformation between ABAP (Advanced Business Application Programming) and EDM (Entity Data Model). This error typically arises in the context of SAP Gateway services, particularly when dealing with OData services.
  Causes of the Error
  
  
  Data Type Mismatch: The data types in the ABAP structure do not match the expected types in the EDM model. For example, if an ABAP field is defined as a string but the EDM expects an integer, this can lead to conversion errors.
  
  
  Null Values: If the ABAP data contains null values that are not handled properly in the EDM, it can cause conversion issues.
  
  
  Incompatible Structures: Changes in the underlying ABAP structure that are not reflected in the EDM can lead to inconsistencies.
  
  
  Incorrect Mapping: If the mapping between ABAP fields and EDM properties is incorrect or incomplete, it can result in conversion errors.
  
  
  Data Length Issues: If the length of the data being passed exceeds the defined length in the EDM, it can cause conversion errors.
  
  
  Solutions
  
  
  Check Data Types: Ensure that the data types in the ABAP structure match those defined in the EDM. You may need to adjust the ABAP data types or modify the EDM model accordingly.
  
  
  Handle Null Values: Implement checks in your ABAP code to handle null values appropriately before they are sent to the EDM.
  
  
  Update EDM Model: If there have been changes to the ABAP structure, ensure that the EDM model is updated to reflect these changes. You may need to regenerate the service or update the metadata.
  
  
  Review Mapping: Verify the mapping between ABAP fields and EDM properties. Ensure that all fields are correctly mapped and that there are no missing fields.
  
  
  Check Data Lengths: Ensure that the data being sent does not exceed the maximum lengths defined in the EDM. If necessary, truncate or adjust the data before sending it.
  
  
  Debugging: Use debugging tools to trace the data flow and identify where the conversion is failing. This can help pinpoint the exact cause of the error.
