  SAP Error Message: WS173 & & was changed (balance in document)
  
  1. Cause
  The error message WS173 occurs during document processing (usually in Financial Accounting or Controlling modules) when the system detects that the balance of the document has been changed unexpectedly. This typically means that the debit and credit totals of the document do not match or have been altered after initial entry or during posting.
  More specifically:
  
  The document was initially created with a certain balance (debits = credits).
  During processing (e.g., posting, editing, or validation), the balance has been changed.
  This inconsistency violates the fundamental accounting principle that every financial document must be balanced.
  
  Common scenarios causing this error:
  
  Manual changes to line items that cause imbalance.
  Programmatic changes (user exits, BAdIs, or custom code) that alter amounts incorrectly.
  Data inconsistencies due to incomplete or incorrect input.
  Currency conversion rounding differences leading to imbalance.
  Posting with incorrect or missing tax or withholding tax data.
  
  
  2. Solution
  To resolve the WS173 error, follow these steps:
  
  Check Document Line Items: Verify that the sum of debit amounts equals the sum of credit amounts in the document.
  Review Recent Changes: Identify any recent changes made to the document or related master data that might have caused imbalance.
  Check Currency and Amounts: Ensure that currency conversions and rounding are handled correctly.
  Validate Tax and Withholding Tax Data: Confirm that tax amounts are correctly calculated and posted.
  Debug Custom Code: If custom enhancements or user exits are involved, debug to check if any code is modifying amounts incorrectly.
  Recreate or Correct Document: If the document is incorrect, cancel and recreate it or correct the line items to restore balance.
  Use SAP Standard Transactions: Use transaction codes like FB03 (Display Document), FB02 (Change Document), or FBL3N (Line Item Display) to analyze the document.
