  • What is the cause and solution for SAP error message CLS_S4_CONV001 - Invalid call; Short fields are not allowed in S/4 HANA target mode ?

    The SAP error message CLS_S4_CONV001 indicates that there is an invalid call due to the use of short fields in S/4HANA target mode. This error typically arises when you are trying to execute a program or a function module that is not compatible with the data model of S/4HANA, which has stricter rules regarding field lengths and types.

    Cause:

    1. Short Fields Usage: In S/4HANA, the data model has been optimized, and the use of short fields (fields with a length of less than the standard length) is not allowed. This is to ensure data integrity and consistency across the system.
    2. Legacy Code: The error may occur if you are using legacy ABAP code that was designed for older versions of SAP, where short fields were permissible.
    3. Data Migration Issues: If you are migrating data from an older SAP system to S/4HANA, the data structure may not comply with the new requirements, leading to this error.

    Solution:

    1. Review and Update Code: Check the ABAP code where the error occurs. Ensure that all fields used in the program or function module comply with the S/4HANA data model. Replace any short fields with their appropriate longer counterparts.
    2. Data Model Compliance: If you are migrating data, ensure that the data being migrated adheres to the S/4HANA data model. This may involve transforming the data to fit the new structure.
    3. Use of Data Dictionary: Utilize the SAP Data Dictionary (SE11) to check the definitions of the fields being used. Ensure that they are defined correctly and are compatible with S/4HANA.
    4. Testing: After making changes, thoroughly test the program or function module to ensure that it works correctly without triggering the error.
    5. Consult Documentation: Refer to SAP's official documentation regarding S/4HANA migration and development guidelines for more detailed information on field lengths and data types.

    Related Information:

    • SAP Notes: Check for any relevant SAP Notes that may provide additional guidance or fixes related to this error.
    • S/4HANA Migration Cockpit: If you are migrating data, consider using the S/4HANA Migration Cockpit, which can help identify and resolve data model issues.
    • ABAP Development Guidelines: Familiarize yourself with the latest ABAP development guidelines for S/4HANA to avoid similar issues in the future.

    By addressing the use of short fields and ensuring compliance with the S/4HANA data model, you should be able to resolve the CLS_S4_CONV001 error.

SAP messages fall into 3 different categories: Error messages (message type = E), Warnings (W) or Informational (I) messages.

An error message will prevent you from continuing your work - it is a hard stop and you need to fix the error before you can proceed. A warning message will stop your work, however, you can then bypass the warning by pressing the Enter key on your keyboard. That said, it is still good practice to investigate the cause of the warning message and address it. An information message will not stop your work and is truly just for informational purposes.
