  SAP Error Message:
  WSTI_MLT_INV_DOC012: There is no document type defined for this counting session
  
  
  Cause:
  This error occurs during inventory counting processes in SAP Warehouse Management (WM) or Inventory Management (IM) when the system cannot find a document type assigned to the counting session you are trying to process. Essentially, the counting session is missing a configuration that links it to a specific document type, which is necessary for posting inventory differences or movements.
  
  Explanation:
  
  In SAP Inventory Management and Warehouse Management, counting sessions (physical inventory documents) are linked to document types that define how inventory postings are handled.
  If the counting session does not have a document type assigned, the system does not know how to post the inventory differences or create the necessary material documents.
  This can happen if the counting session was created incorrectly or if the configuration for document types related to physical inventory is incomplete or missing.
