• What is the cause and solution for SAP error message CNV_00001203 - &1 has neither type C, P nor T (probably structure). ?

  The SAP error message CNV_00001203 typically indicates that a certain object (like a field or a structure) does not have a valid type assigned to it. The message suggests that the object in question is neither of type C (character), P (packed number), nor T (date/time), which are the expected types for the operation being performed. This error often arises during data migration or conversion processes, particularly when using SAP's Conversion Tools.
  Cause:
  
  Invalid Data Type: The object being processed has an invalid or unsupported data type that does not match the expected types (C, P, T).
  Structure Definition Issues: The structure or table definition may be incorrect or incomplete, leading to the absence of a valid type.
  Data Mapping Errors: During data migration, the mapping of fields from the source to the target system may not have been done correctly, resulting in fields being assigned incorrect types.
  
  Solution:
  
  Check Data Types: Review the data types of the fields in the structure or table that is causing the error. Ensure that they are defined as either C, P, or T.
  Adjust Structure Definitions: If the structure is custom or modified, ensure that it is correctly defined in the ABAP Dictionary (SE11). You may need to adjust the field types to match the expected types.
  Review Data Mapping: If this error occurs during a data migration process, check the mapping configuration to ensure that all fields are correctly mapped to the appropriate types.
  Debugging: If you have access to the development environment, you can debug the program or function module that is generating this error to identify the exact point of failure and the data being processed.
