  Error Message
  WG315: Gross PO weight could not be correctly determined for purchase order &
  
  Cause
  This error occurs when SAP is unable to calculate or determine the gross weight of a Purchase Order (PO) because the system lacks the necessary data or the data is inconsistent. The gross weight is typically calculated based on the weights of the individual materials/items included in the PO.
  Common causes include:
  
  Missing or incomplete weight data: The material master records for one or more items in the PO do not have the gross weight or net weight maintained.
  Incorrect unit of measure: The weight unit in the material master or PO item is missing or inconsistent.
  Configuration issues: The system settings for weight determination or unit conversion are not properly maintained.
  Data inconsistencies: The PO contains items with zero or invalid weight entries.
  Custom enhancements or user exits: Custom code that tries to calculate or validate weight may cause issues if not properly handled.
  
  
  Solution
  To resolve the WG315 error, follow these steps:
  
  
  Check Material Master Data:
  
  Go to transaction MM03 (Display Material).
  Check the Basic Data 1 tab for the Gross Weight and Net Weight fields.
  Ensure that the weights are maintained and the unit of measure is correct.
  If missing, maintain the weights in the material master using MM02.
  
  
  
  Verify Unit of Measure:
  
  Ensure that the weight unit (e.g., KG, LB) is consistent and correctly maintained in the material master.
  Check the PO item unit of measure and ensure it matches or is convertible.
  
  
  
  Check Purchase Order Items:
  
  Review the PO items in transaction ME23N.
  Verify that all items have valid material numbers and that the materials have weights maintained.
  
  
  
  Review Configuration:
  
  Check the settings for weight determination in IMG under:
  
  Logistics Execution ? Shipping ? Basic Shipping Functions ? Define Weight Determination
  
  
  Ensure that the system is configured to calculate weights correctly.
  
  
  
  Check for Custom Code:
  
  If there are user exits or BAdIs related to PO processing or weight calculation, review them for errors or missing handling.
  
  
  
  Recalculate or Update PO:
  
  Sometimes, simply saving the PO again after correcting the material master data can resolve the issue.
  Use transaction ME22N to edit and save the PO.
  
  
  
  
  Additional Information
  
  The gross weight of a PO is important for logistics, shipping, and transportation planning.
  If the PO contains non-stock items or services, these may not have weights, so the system might fail to calculate the total weight.
  In some cases, the error might appear during delivery creation or goods receipt if the system tries to determine the weight based on the PO.
