  SAP Error Message:
  
  W5038 - "To switch from multi to single, you must provide just one account assignment."
  
  Cause:
  This warning message occurs when you attempt to change the account assignment category from multiple account assignments (multi) to a single account assignment in a document or transaction, but the system detects that more than one account assignment item is still present.
  In other words, the system expects only one account assignment item when switching to a single account assignment category, but multiple account assignments are still maintained in the document or line item.
  
  Explanation:
  
  Multi account assignment means that the costs or revenues are split across multiple cost centers, orders, projects, etc.
  Single account assignment means that the entire amount is assigned to one single cost object.
  When switching from multi to single, the system requires that only one account assignment exists to avoid ambiguity in postings.
  
  
  Solution:
  
  Review the account assignment items in the document or transaction.
  Ensure that only one account assignment item is maintained before switching the account assignment category to single.
  Delete or consolidate multiple account assignments so that only one remains.
  After this, you can successfully switch from multi to single account assignment.
