• What is the cause and solution for SAP error message AQV321 - This line must not be deleted ?

  The SAP error message AQV321, which states "This line must not be deleted," typically occurs in the context of document processing, such as when working with purchase orders, sales orders, or other transactional documents. This error indicates that the system has identified a line item that is critical and cannot be removed due to business rules or dependencies.
  Causes:
  
  Critical Line Item: The line item may be essential for the integrity of the document, such as a mandatory item or a line that has already been processed in some way (e.g., goods receipt, invoice).
  Dependencies: There may be other documents or processes that depend on this line item, making it necessary to retain it.

  Review Document: Check the document to understand why the line item is critical. Look for any dependencies or related documents that may be affecting the ability to delete the line.
  Consult with Business Process Owners: If the line item seems unnecessary, consult with relevant stakeholders to determine if it can be modified or if there is a valid reason for its retention.
  Check for Open Transactions: Ensure that there are no open transactions (like deliveries or invoices) associated with the line item that would prevent its deletion.
  Use Alternative Actions: If deletion is not possible, consider whether you can modify the line item instead (e.g., changing quantities, prices, or statuses).
  System Configuration: If you believe the restriction is overly strict, you may need to consult with your SAP Basis or configuration team to review the settings that govern line item deletions.
