Specifically, the error states that the invoice IDs must follow an incremental sequence. This means that the system expects the invoice IDs to be in a continuous order without any gaps.

  Correct the Sequence: If gaps are found, you will need to either:
  
  Add the missing invoice IDs if they were supposed to be created.
  Remove the non-sequential IDs from the processing batch if they are not needed.
  
  
  Data Uploads: If you are uploading data (e.g., through a file or interface), ensure that the data source does not contain gaps in the invoice IDs.
  Configuration Review: If the issue persists, review the configuration settings related to invoice numbering in your SAP system. Consult with your SAP administrator or functional consultant to ensure that the settings align with your business requirements.
