  • What is the cause and solution for SAP error message WFF_FORM_GENERATOR109 - Special characters and lower-case letters are not allowed in name &1 ?

    Certainly! Here's a detailed explanation for the SAP error message:


    SAP Error Message:

    WFF_FORM_GENERATOR109
    Text: Special characters and lower-case letters are not allowed in name &1


    Cause:

    This error occurs when you try to create or use a name (such as a workflow container element, step name, or other identifiers in the SAP Workflow Builder or form generator) that contains either:

    • Special characters (e.g., @, #, $, %, &, *, etc.)
    • Lower-case letters (a, b, c, ... z)

    SAP workflow and form naming conventions require that names only contain uppercase letters (A-Z), digits (0-9), and possibly underscores (_). Lower-case letters and special characters are not allowed because they can cause inconsistencies or errors in processing.


    Solution:

    • Rename the object (e.g., container element, step, form field) so that it contains only uppercase letters, digits, and underscores.
    • Avoid any special characters or spaces in the name.
    • For example, instead of myField1, use MYFIELD1. Instead of field@name, use FIELD_NAME.

    Related Information:

    • This naming restriction is common in SAP Workflow Builder and form generators to ensure compatibility and avoid parsing errors.
    • Always follow SAP naming conventions for workflow container elements and other identifiers:
      • Use uppercase letters (A-Z)
      • Use digits (0-9) if needed
      • Use underscores (_) to separate words if necessary
    • Avoid spaces, special characters, and lowercase letters.
    • If you are importing or copying workflows or forms from external sources, check and correct the names accordingly.
    • This error is a preventive measure to avoid runtime errors or issues in workflow execution or form generation.

    If you continue to face issues, check the exact object name causing the error and correct it as per the above guidelines.


    Summary:
    Cause: Name contains special characters or lowercase letters.
    Solution: Rename to uppercase letters, digits, and underscores only.
    Related: SAP workflow and form naming conventions.


    If you need help identifying the exact object causing the error or how to rename it, please provide more context or screenshots.
