• What is the cause and solution for SAP error message WSTRN055 - Enter a delivery date ?

  SAP Error Message:
  
  WSTRN055 - Enter a delivery date
  
  Cause:
  This warning message appears when you are creating or processing a transaction (such as a sales order, purchase order, or production order) in SAP and the system requires a delivery date to be entered but it is missing or incomplete. The delivery date is a mandatory field for scheduling and planning purposes, and without it, the system cannot proceed with the transaction.
  
  When does it occur?
  
  During sales order creation (VA01/VA02) when the delivery date is not specified.
  During purchase order creation (ME21N/ME22N) if the delivery date is missing.
  In production orders or other logistics documents where a delivery or required date is mandatory.
  When the system’s configuration or user exit enforces the entry of a delivery date.
  
  
  Solution:
  
  
  Enter a valid delivery date:  
  
  Go to the relevant field (usually labeled "Delivery Date," "Req. Delivery Date," or "Delivery Schedule") and input a valid date.
  The date should be within the allowed range (not in the past or outside the planning horizon).
  
  
  
  Check the document type settings:  
  
  Sometimes, the document type or item category requires a delivery date. Verify the configuration in transaction codes like OVZ9 (for sales document types) or OMBA (for purchase document types).
  
  
  
  Check user exits or enhancements:  
  
  If the delivery date is not being prompted but the system expects it, check if there are any custom validations or user exits that enforce this field.
  
  
  
  Review copy control settings:  
  
  If the document is created by copying from another document, ensure that the delivery date is correctly copied or entered.
  
  
  
  Check calendar and factory calendar settings:  
  
  Sometimes, the delivery date must fall on a working day. Verify the calendar settings if the system rejects the date.
  
  
  
  
  Additional Information:
  
  Message Class: WSTRN  
  Message Number: 055  
  This is typically a warning message, meaning you can proceed after entering the date, but it is recommended to provide the delivery date for proper scheduling.
