• What is the cause and solution for SAP error message WG018 - Total line quantities larger than item quantities ?

  Certainly! Here's a detailed explanation of the SAP error message WG018 - Total line quantities larger than item quantities:
  
  SAP Error Message: WG018
  Text: Total line quantities larger than item quantities
  
  Cause:
  This error occurs when the sum of the quantities entered in the individual lines of a goods movement or delivery document exceeds the total quantity specified for the item. In other words, the total quantity distributed across the lines is greater than the overall item quantity allowed or defined in the document.
  Common scenarios include:
  
  When creating or changing delivery documents (e.g., outbound deliveries, transfer orders).
  When entering picking quantities or goods movement quantities.
  When the system checks consistency between item quantity and line quantities.
  
  
  Explanation:
  
  Each item in a document has a defined quantity.
  The document may have multiple lines or sub-lines representing partial quantities.
  The sum of these line quantities must not exceed the total item quantity.
  If the sum exceeds, SAP throws WG018 to prevent inconsistencies in inventory or delivery processing.
  
  
  Solution:
  
  
  Check the quantities entered:
  
  Review the quantities entered in each line of the document.
  Ensure that the sum of all line quantities does not exceed the total item quantity.
  
  
  
  Adjust line quantities:
  
  Reduce the quantities in the lines so that their total matches or is less than the item quantity.
  If partial deliveries or partial goods movements are intended, ensure the quantities reflect that correctly.
  
  
  
  Verify item quantity:
  
  Confirm that the item quantity itself is correct and reflects the actual quantity to be processed.
  If the item quantity is incorrect, adjust it accordingly.
  
  
  
  Check for rounding or unit of measure issues:
  
  Sometimes, rounding differences or unit of measure conversions can cause quantity mismatches.
  Verify that units of measure are consistent and conversions are correct.
  
  
  
  Use SAP transaction logs or document flow:
  
  Check the document flow or change logs to identify where the quantity mismatch originated.
  
  
  
  
  Related Information:
  
  Transaction codes: VL02N (Change Outbound Delivery), VL01N (Create Outbound Delivery), LT03 (Create Transfer Order), MIGO (Goods Movement)
  SAP Notes: Search for WG018 in SAP Service Marketplace or SAP Support Portal for any specific notes or patches.
  Configuration: Check if any user exits or BAdIs are modifying quantities during document processing.
  Unit of Measure: Always ensure consistent use of base unit of measure to avoid quantity mismatches.
  
  
  Summary:
  The WG018 error prevents the system from processing documents where the sum of line quantities exceeds the total item quantity, ensuring data integrity in inventory and delivery processes. Correcting the quantities to maintain consistency resolves the error.
