• What is the cause and solution for SAP error message WRF_AT146 - Synchronization is not possible when purchase order UoMs differ ?

  Certainly! Here's a detailed explanation regarding the SAP error message WRF_AT146: Synchronization is not possible when purchase order UoMs differ:
  
  Error Message
  WRF_AT146: Synchronization is not possible when purchase order UoMs differ
  
  Cause
  This error occurs during the synchronization process between a Purchase Requisition (PR) and a Purchase Order (PO) when the Unit of Measure (UoM) in the PO differs from the UoM in the PR for the same item.
  
  SAP requires that the UoM in the PO and PR match exactly to allow synchronization.
  If the UoMs differ (for example, PR is in "EA" (Each) and PO is in "BOX"), SAP cannot synchronize the data because it cannot automatically convert or reconcile the quantities.
  This is a standard validation to ensure data consistency and avoid quantity or price mismatches.
  
  
  When does it occur?
  
  When you try to convert or synchronize a Purchase Requisition into a Purchase Order.
  When you try to update or synchronize changes between PR and PO.
