• What is the cause and solution for SAP error message VV156 - Priority for 'document number' must be higher than for 'document item' ?

  The SAP error message VV156 indicates that there is a priority issue between a document number and its associated document item. This error typically arises in the context of sales and distribution (SD) or logistics processes where document processing priorities are defined.
  
  Cause:
  The error occurs when the priority assigned to a document item is higher than the priority assigned to the overall document. In SAP, each document (like a sales order) and its items (like individual line items in that order) can have different priority levels. The system expects that the document's priority should be equal to or higher than that of its items. If the item has a higher priority than the document, the system raises this error to maintain logical consistency.
  
  Solution:
  To resolve this error, you need to ensure that the priority of the document is set to be equal to or higher than the priority of its items. Here
