• What is the cause and solution for SAP error message RU522 - Underdelivery found on posting predecessor ?

  The SAP error message RU522 "Underdelivery found on posting predecessor" typically occurs in the context of inventory management or goods movement in SAP. This error indicates that there is an issue with the quantity of goods being delivered or posted in relation to a previous document (the predecessor) that has not been fully delivered.
  Cause:
  
  Underdelivery: The predecessor document (such as a purchase order or production order) has a quantity that has not been fully delivered. For example, if a purchase order was created for 100 units, but only 80 units were delivered, the system will flag this as an underdelivery when trying to post a subsequent document that references this order.
  Document Flow: The error can also arise if there are inconsistencies in the document flow, such as trying to post a goods receipt or invoice for a quantity that exceeds what has been delivered or is still open.
  Configuration Issues: Sometimes, the configuration settings in the system regarding delivery tolerances or underdelivery handling may lead to this error.
  
  Solution:
  
  Check Predecessor Document: Review the predecessor document (e.g., purchase order, production order) to confirm the delivered quantities. Ensure that the quantities match what is expected and that there are no outstanding deliveries.
  Complete Deliveries: If there are outstanding quantities, complete the necessary deliveries before attempting to post the new document.
  Adjust Quantities: If you are trying to post a document that exceeds the delivered quantity, adjust the quantities in your posting to match the delivered amount.
  Review Configuration: If the issue persists, check the configuration settings related to underdelivery tolerances in the system. You may need to adjust these settings based on your business requirements.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on handling underdelivery scenarios in your version of SAP.
