  SAP Error Message:
  WT813 Recipient &1, material &2: fields to be converted already maintained
  
  Meaning / 
  Cause:
  This error occurs during the creation or maintenance of stock transport orders (STO) or transfer postings involving warehouse tasks or warehouse management (WM) processes. Specifically, it indicates that the fields you are trying to convert or update for a particular recipient (plant or storage location) and material have already been maintained or converted previously.
  In other words, the system detects that the conversion or update you are attempting is redundant because the relevant data fields (such as stock types, stock categories, or WM-related fields) have already been set or converted for the given recipient and material.
  This often happens in scenarios involving:
  
  Conversion of stock from one stock type to another (e.g., unrestricted to blocked stock).
  Transfer postings where the system tries to convert fields that are already converted.
  Warehouse management processes
