  The SAP error message WAB120, which states "Completing supplier settlements from two-sided documents is not allowed," typically occurs in the context of supplier invoice processing and settlement in SAP. This error indicates that there is an issue with the way the documents are structured or processed, particularly when dealing with two-sided documents (e.g., documents that involve both a supplier and a customer).
  Cause:
  
  Two-Sided Document: The error arises when you attempt to settle a supplier invoice that is linked to a two-sided document (e.g., a document that involves both a supplier and a customer). SAP does not allow settlements to be completed in this scenario.
  Document Type: The document type may not be configured to allow for the type of settlement you are trying to perform.
  Configuration Issues: There may be configuration settings in the SAP system that restrict the processing of two-sided documents for settlements.
  
  Solution:
  
  Check Document Type: Verify the type of document you are trying to settle. Ensure that it is not a two-sided document or that it is configured correctly for the type of settlement you are attempting.
  Separate Settlements: If the document is indeed a two-sided document, consider separating the settlements. You may need to process the supplier and customer settlements independently.
  Review Configuration: Check the configuration settings in the SAP system related to document types and settlements. Ensure that the settings allow for the type of transactions you are processing.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling two-sided documents and settlements.
  Contact SAP Support: If the issue persists, consider reaching out to SAP support or your internal SAP team for further assistance. They may provide insights specific to your system configuration.
