  • What is the cause and solution for SAP error message T5175 - Number group cannot be deleted because it is being used! ?

    The SAP error message T5175 indicates that a number group cannot be deleted because it is currently in use. This typically occurs in the context of number ranges, which are used in various SAP modules to generate unique identifiers for documents, transactions, or master data.

    Cause:

    The error arises when you attempt to delete a number group that is still assigned to one or more objects or transactions. Common reasons include:

    • The number group is assigned to a document type, such as invoices or purchase orders.
    • The number group is being used in a configuration setting, such as in the creation of master data (e.g., customer or vendor numbers).
    • There are existing documents or records that have already utilized the number range from the group you are trying to delete.

    Solution:

    To resolve this issue, you can follow these steps:

    1. Identify Usage: Determine where the number group is being used. You can check:

      • Document types that are linked to the number group.
      • Any configuration settings in the relevant modules (e.g., FI, MM, SD) that reference the number group.
    2. Remove Assignments: If the number group is assigned to any document types or configurations, you will need to:

      • Change the assignment of the document type to a different number group.
      • Update any configurations that reference the number group.
    3. Check Existing Documents: Ensure that there are no existing documents that have been created using the number range from the group you want to delete. If there are, you may need to archive or delete those documents if appropriate.

    4. Use Transaction Codes: You can use transaction codes like SNRO (Number Range Objects) to manage number ranges and check their status.

    5. Consult Documentation: If you are unsure about the implications of changing or deleting a number group, consult SAP documentation or your SAP administrator for guidance.

    6. Testing: After making changes, test to ensure that the new configurations work as expected and that the number group can be deleted without issues.

    Related Information:

    • SAP Notes: Check SAP Notes for any specific issues or patches related to number range management.
