• What is the cause and solution for SAP error message WG401 - Not all information exists that is required for order splitting ?

  Certainly! Here's a detailed explanation for the SAP error message WG401: "Not all information exists that is required for order splitting":
  
  Error Message: WG401
  Text: Not all information exists that is required for order splitting
  
  Cause:
  This error occurs during the order splitting process in SAP Sales and Distribution (SD) when the system tries to split a sales order into multiple sub-orders but finds that some mandatory data or configuration required for splitting is missing or incomplete.
  Order splitting is used to divide a sales order into multiple delivery or billing documents based on certain criteria (e.g., shipping point, delivery date, material group, etc.). For this to work correctly, the system needs specific information to determine how to split the order.
  Common causes include:
  
  Missing or incomplete order splitting profile configuration.
  Missing or incomplete order splitting rules or criteria.
  Required fields or data in the sales order that are blank or inconsistent.
  Missing assignment of order splitting profile to the sales document type or sales area.
  Incomplete or missing partner determination or shipping point determination data.
  Custom enhancements or user exits that interfere with the order splitting logic.
  
  
  Solution:
  
  
  Check Order Splitting Configuration:
  
  Go to transaction SPRO ? Sales and Distribution ? Sales ? Sales Documents ? Order Splitting.
  Verify that the order splitting profile is correctly defined.
  Check the splitting criteria and rules to ensure they are complete and correctly maintained.
  
  
  
  Assign Order Splitting Profile:
  
  Ensure that the order splitting profile is assigned to the relevant sales document type and sales area.
  This is done in the customizing under sales document type settings.
  
  
  
  Verify Sales Order Data:
  
  Check the sales order for completeness of data required for splitting.
  Ensure that fields like shipping point, delivery date, material group, or any other splitting criteria fields are filled correctly.
  
  
  
  Check Partner and Shipping Point Determination:
  
  Verify that partner functions and shipping points are correctly determined and assigned.
  Missing shipping point can cause order splitting to fail.
  
  
  
  Debug or Analyze User Exits / BAdIs:
  
  If there are custom enhancements related to order splitting (e.g., user exits like USEREXIT_SPLIT_ORDER), check if they are causing the issue.
  Debug the order splitting process to identify missing data or logic errors.
  
  
  
  Use SAP Notes and Documentation:
  
  Search for relevant SAP Notes that might address known issues with order splitting.
  Example SAP Note: 123456 (hypothetical) might provide patches or corrections.
