• What is the cause and solution for SAP error message LD108 - Units could not be changed because line balances exist. ?

  The SAP error message LD108 indicates that you are trying to change the units of measure for a line item in a document (such as a purchase order, sales order, or delivery) where line balances exist. This typically occurs in the context of logistics and inventory management, where the system prevents changes that could lead to inconsistencies in inventory or financial records.
  Cause:
  The error occurs because:
  
  Line Balances Exist: There are already quantities or balances recorded for the item in the specified unit of measure. This could be due to goods receipts, goods issues, or other transactions that have already been processed.
