• What is the cause and solution for SAP error message WSTI012 - Please save data you changed before posting differences ?

  SAP Error Message:
  
  WSTI012 – "Please save data you changed before posting differences"
  
  Cause:
  This error occurs in SAP when you attempt to post differences (e.g., in inventory differences, physical inventory, or other adjustment postings) without first saving the changes you made in the document or transaction. Essentially, the system requires that all modifications be saved before you can proceed with posting the differences.
  In many SAP transactions, especially those related to inventory management (e.g., MI01, MI04, MI07), you enter or change data and then post the differences. If you try to post without saving the changes, the system throws this message to prevent inconsistencies or incomplete data from being posted.
  
  Solution:
  
  Save your changes first: Before clicking the "Post Differences" button or equivalent, make sure to save the data you have entered or modified.
  Typically, there is a Save button or menu option in the transaction screen. Use it to save your entries.
  After saving, proceed to post the differences.
  If you are working in a custom or Z transaction, ensure that the program logic enforces saving before posting.
  
  
  Related Information:
  
  This message is common in Physical Inventory (PI) transactions such as:
  
  MI01 (Create Physical Inventory Document)
  MI04 (Enter Inventory Count)
  MI07 (Post Inventory Differences)
  
  
  The message ensures data integrity by preventing posting of unsaved or incomplete data.
  If you encounter this message repeatedly even after saving, check for:
  
  User authorizations
  Possible custom enhancements or user-exits that might interfere with the save/post logic
  System locks or inconsistencies in the document
