• What is the cause and solution for SAP error message /SAPAPO/MC01091 - The product is referenced itself, recursive reference not allowed ?

  The SAP error message /SAPAPO/MC01091 indicates that there is a recursive reference in the product master data.

  Solution:
  
  Check BOM: Review the BOM for the product in question. Ensure that the product is not listed as a component of itself.
  Review Product Master Data: Check the product master data for any self-references in the production process or other related configurations.
  Correct Data Entry: If you find any self-references, correct them by removing the product from its own BOM or production process.
  Use Transaction Codes: Use transaction codes like CS03 (Display BOM) or MM03 (Display Material) to analyze the product structure and identify the issue.
  Consult Documentation: Refer to SAP documentation or help resources for guidance on setting up BOMs and product master data correctly.
