  SAP Error Message: VN352
  Message Text:
  
  Object type & is assigned to the item in application &
  
  1. Cause
  This error occurs when you try to perform an operation on a purchasing document item (such as a purchase order or contract item) that already has an object of a certain type assigned to it in a specific application. 
  In SAP MM (Materials Management), certain objects (like service entry sheets, delivery notes, or inspection lots) are linked to purchasing document items. The system prevents duplicate or conflicting assignments of the same object type to the same item to maintain data consistency and integrity.
  For example, if a service entry sheet (object type 'ES') is already assigned to a purchase order item, and you try to assign another service entry sheet or a conflicting object type to the same item, the system will raise this error.
  
  2. When does it occur?
  
  When creating or changing purchasing documents (PO, contracts, scheduling agreements).
  When assigning or linking objects like service entry sheets, delivery documents, or inspection lots to purchase order items.
  During goods receipt or invoice verification processes if the system detects conflicting object assignments.
  
  
  3. Solution
  
  
  Check existing assignments:
  
  Review the purchasing document item to see which object types are already assigned. You can do this by checking the item history or related documents.
  
  
  Avoid duplicate assignments:
  
  Ensure that you are not trying to assign the same object type multiple times to the same item.
  
  
  Correct the process flow:
  
  If the assignment is incorrect, remove or correct the existing object assignment before proceeding.
  
  
  Use transaction codes:  
  
  Use ME23N to display the purchase order and check the item history.
  Use ME33K for contracts.
  Use ML81N for service entry sheets.
  Use MB51 or MB03 to check material documents.
  
  
  
  Consult with functional team:
  
  If unsure about the object types and their assignments, consult with your MM or SD functional consultant to understand the business process and correct the document flow.
