• What is the cause and solution for SAP error message CM_SUB_BAPI012 - In target mode no character values in short fields are allowed ?

  The SAP error message CM_SUB_BAPI012 indicates that in target mode, no character values are allowed in short fields. This typically occurs when you are trying to transfer data using a BAPI (Business Application Programming Interface) and the data being passed does not conform to the expected format.
  Cause:
  
  Data Type Mismatch: The error usually arises when character values are being passed to fields that are defined as numeric or have a specific length constraint in the target structure.
  Field Length Exceeded: If the data being sent exceeds the defined length of the target field, it can trigger this error.
  Incorrect Mapping: The mapping of source fields to target fields may not be correctly defined, leading to character data being sent to fields that expect numeric or other types of data.
  
  Solution:
  
  Check Data Types: Review the data types of the fields in the BAPI interface. Ensure that the data being passed matches the expected types. For example, if a field is defined as numeric, ensure that you are not passing character strings.
  Trim Data: If the data being sent is longer than the target field allows, consider trimming the data to fit within the defined length.
  Validate Input Data: Before calling the BAPI, validate the input data to ensure it meets the requirements of the target structure.
  Review Mapping: If you are using middleware or an integration tool, check the mapping configuration to ensure that the source fields are correctly mapped to the target fields.
  Debugging: Use debugging tools in SAP to trace the data being passed to the BAPI. This can help identify where the incorrect data is coming from.
  
  Related Information:
  
  BAPI Documentation: Refer to the specific BAPI documentation to understand the expected input parameters and their data types.
  SAP Notes: Check SAP Notes for any known issues or updates related to the BAPI you are using.
  Data Dictionary: Use transaction SE11 to look up the data dictionary for the relevant tables and structures to understand the field definitions and constraints.
  
  By following these steps, you should be able to resolve the CM_SUB_BAPI012 error and ensure that the data being passed to the BAPI is in the correct format.
