• What is the cause and solution for SAP error message WSTRN056 - Specify either multiple delivery dates or a single delivery date ?

  SAP Error Message:
  
  WSTRN056 - Specify either multiple delivery dates or a single delivery date
  
  Cause:
  This error occurs in SAP when creating or processing a delivery schedule or schedule line, and the system detects that both a single delivery date and multiple delivery dates are specified simultaneously for the same item or schedule line. SAP requires that you specify either a single delivery date or multiple delivery dates, but not both at the same time.
  This typically happens in scenarios involving scheduling agreements, purchase orders, or sales orders where delivery dates are managed. The system enforces this to avoid ambiguity in delivery scheduling.
  
  Explanation:
  
  Single delivery date: One fixed date for delivery.
  Multiple delivery dates: Several dates with quantities assigned to each date (schedule lines).
  
  If both are entered, SAP cannot determine which delivery date(s) to use, hence the error.
  
  Solution:
  
  Review the delivery schedule or schedule lines in the document.
  Ensure that only one of the following is specified:
  
  A single delivery date (one date for the entire quantity).
  Multiple delivery dates (schedule lines with different dates and quantities).
  
  
  Remove or correct the conflicting date entries.
  Save the document again.
  
  
  How to fix in practice:
  
  
  In Purchase Order or Scheduling Agreement:
  
  Go to the item schedule lines.
  Check if a single delivery date is entered in the header or item level.
  Check if multiple schedule lines with different delivery dates exist.
  Delete or adjust so that only one method is used.
  
  
  
  In Sales Order or Delivery Document:
  
  Check the delivery schedule lines.
  Remove either the single delivery date or the multiple schedule lines.
