• What is the cause and solution for SAP error message OT803 - Line &1: Sequence is not numbered sequentially ?

  The SAP error message OT803 "Line &1: Sequence is not numbered sequentially" typically occurs in the context of document processing, particularly when dealing with line items in a document such as a purchase order, invoice, or sales order. This error indicates that the line items in the document are not in the expected sequential order, which can lead to issues in processing or reporting.
  Cause:
  
  Non-sequential Line Numbers: The line items in the document are not numbered in a continuous sequence. For example, if you have line items numbered 1, 2, 4, and 5, the system will throw this error for line 4 because line 3 is missing.

  Solution:
  
  Check Line Item Sequence: Review the line items in the document to ensure they are numbered sequentially. Correct any discrepancies by renumbering the line items.
  Recreate the Document: If the document is not too complex, consider recreating it to ensure that the line items are added in the correct sequence.
