• What is the cause and solution for SAP error message SHDB202 - Type conversion error ABAP to DDIC: type &1 reason: &2 ?

  The SAP error message SHDB202, which indicates a "Type conversion error ABAP to DDIC," typically occurs during the execution of a batch input session or when using transaction recording in SAP. This error suggests that there is a mismatch between the data types in ABAP and the Data Dictionary (DDIC) definitions.
  Cause:
  The error can be caused by several factors, including:
  
  
  Data Type Mismatch: The data being passed from the ABAP program does not match the expected data type defined in the DDIC. For example, trying to assign a character string to a numeric field.
  
  
  Field Length Issues: The length of the data being passed exceeds the maximum length defined in the DDIC for that field.
  
  
  Incorrect Mapping: When recording a transaction, the fields may not have been correctly mapped, leading to incorrect data types being used.
  
  
  Null Values: Attempting to assign a null value to a field that does not accept nulls can also trigger this error.
  
  
  Solution:
  To resolve the SHDB202 error, you can take the following steps:
  
  
  Check Data Types: Review the data types of the fields in the ABAP program and compare them with the corresponding fields in the DDIC. Ensure that they match.
  
  
  Adjust Field Lengths: If the data being passed exceeds the defined length in the DDIC, consider truncating the data or adjusting the DDIC definition if appropriate.
  
  
  Review Transaction Recording: If the error occurs during a recorded transaction, go back to the recording and ensure that all fields are correctly mapped and that the data types are appropriate.
  
  
  Debugging: Use the ABAP debugger to step through the code and identify where the type conversion error is occurring. This can help pinpoint the exact field or variable causing the issue.
  
  
  Check for Null Values: Ensure that any fields that do not accept null values are being populated correctly.
  
  
  Consult Documentation: If you are unsure about the data types or field definitions, refer to the SAP documentation or consult with a colleague who has experience with the specific transaction or program.
