• What is the cause and solution for SAP error message CMM_TIER_PRC018 - Call-off quantity cannot be increased due to existing inovice ?

  The SAP error message CMM_TIER_PRC018 indicates that the call-off quantity for a particular item cannot be increased because there is an existing invoice associated with that item. This typically occurs in scenarios involving call-off orders or blanket purchase orders where the quantity has already been invoiced, and any attempt to increase the call-off quantity would violate the constraints set by the existing invoice.
  Cause:
  
  Existing Invoice: The primary cause of this error is that there is already an invoice created for the call-off quantity that you are trying to increase. SAP prevents changes to the call-off quantity to maintain data integrity and avoid discrepancies in financial records.
  Contractual Obligations: There may be contractual terms that restrict changes to the call-off quantities once invoicing has occurred.
  System Configuration: Certain configurations in the SAP system may enforce strict rules regarding call-off quantities and invoicing.
  
  Solution:
  
  Review Existing Invoices: Check the existing invoices related to the call-off order. If the invoice is incorrect or needs to be adjusted, you may need to reverse or cancel the invoice before making changes to the call-off quantity.
  Adjust Call-off Quantity: If the invoice is valid and should remain, you may need to create a new call-off order or adjust the existing order in a way that does not conflict with the invoiced quantities.
  Consult with Procurement: Engage with your procurement or finance team to understand the implications of changing the call-off quantity and to ensure compliance with any contractual obligations.
  System Configuration: If this is a recurring issue, consider reviewing the system configuration with your SAP administrator to see if adjustments can be made to allow for more flexibility in handling call-off quantities and invoicing.
  
  Related Information:
  
  Transaction Codes: You may need to use transaction codes like ME23N (Display Purchase Order) or ME22N (Change Purchase Order) to review and modify purchase orders.
  Documentation: Refer to SAP documentation or help files for more detailed information on handling call-off orders and invoicing processes.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling call-off quantities and invoices.
  
  If the issue persists after following these steps, it may be beneficial to consult with your SAP support team or a technical consultant for further assistance.
