  SAP Error Message:
  WZRE_EXT_POST001: Document category must be invoice or settlement
  
  Cause:
  This error occurs during the posting of a document in SAP when the document category assigned to the transaction is neither an invoice nor a settlement. The system expects the document category to be one of these two types for the particular posting process or transaction type being executed.
  Common scenarios include:
  
  Attempting to post a document with an incorrect or missing document category.
  Custom or external interfaces (e.g., IDocs, BAPIs) passing an invalid document category.
  Configuration issues where the document category is not properly set or mapped.
  Posting a document in a process that strictly requires invoice or settlement document categories (e.g., in contract settlement, vendor invoice processing, or external service management).
  
  
  Solution:
  
  
  Check Document Category:
  
  Verify the document category being used in the posting.
  Ensure it is set to either Invoice (usually 'RE') or Settlement (usually 'AB') depending on the business process.
  
  
  
  Review Posting Transaction:
  
  Confirm that the transaction or program you are using supports the document category you are trying to post.
  For example, if posting a vendor invoice, the document category should be 'RE'.
  
  
  
  Check Configuration:
  
  Review the configuration in transaction codes like OBYC, OBA7, or related IMG settings where document categories are defined or mapped.
  Ensure that the document type and category are correctly assigned for the relevant transaction.
  
  
  
  Interface or Custom Code:
  
  If the posting is done via an interface (IDoc, BAPI, or custom program), check the data being passed.
  Correct the document category field in the interface or program to 'Invoice' or 'Settlement'.
