• What is the cause and solution for SAP error message G0123 - FS items in the hierarchies of C/A &2 already assigned to item &1 ?

  The SAP error message G0123 indicates that there is an issue with the assignment of financial statement (FS) items in the hierarchies of a chart of accounts (C/A). Specifically, it means that the FS items you are trying to assign to a particular item are already assigned to another item. This can occur during the configuration of financial statement versions or when trying to modify existing assignments.
  Cause:
  
  Duplicate Assignment: The FS items you are trying to assign are already linked to another financial statement item, which violates the uniqueness requirement for FS item assignments.
  Configuration Error: There may be an error in the configuration of the financial statement version or the chart of accounts.
  Hierarchy Structure: The hierarchy structure may not be set up correctly, leading to conflicts in assignments.
  
  Solution:
  
  Check Existing Assignments: Review the current assignments of the FS items in question. You can do this by navigating to the financial statement version configuration and checking the hierarchy for the specific chart of accounts.
  Remove Duplicate Assignments: If you find that the FS items are indeed assigned to another item, you will need to either remove the existing assignment or choose different FS items for your current assignment.
  Modify Hierarchy: If necessary, adjust the hierarchy structure to ensure that FS items are uniquely assigned to the appropriate items.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on configuring financial statement versions and hierarchies.
  Testing: After making changes, test the configuration to ensure that the error does not reoccur.
