SO112 - Details

• The SAP error message SO112, which states that "Document <&> cannot be changed," typically occurs when you attempt to modify a document (such as a sales order, delivery, or invoice) that is in a status that does not allow changes. This can happen for several reasons, including:
  Causes:
  
  Document Status: The document may be in a status that prohibits changes, such as being completed, archived, or already processed in a subsequent step (e.g., invoiced).
  Authorization Issues: The user may not have the necessary authorizations to make changes to the document.
  Document Locking: The document might be locked by another user or process, preventing any modifications.
  Custom Logic: There may be custom validations or business rules implemented in the system that restrict changes to certain documents under specific conditions.
  
  Solutions:
  
  Check Document Status: Review the status of the document. If it is completed or processed, you may need to create a new document or reverse the existing one,
