CNV_00001203 - Details

• 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.
