26B ASN Creation Assistant Email - ASN with Multiple Purchase Orders

Summary: We are testing the seeded agent 'ASN Creation Assistant Email' that was released in 26B. One of the scenario that we came across is that a supplier can send a ASN with lines belonging to multiple purchase orders (Typical delivery grouping). When we prepared test data with one single ASN header (e.g. ASN Number: ASN001) and multiple lines (e.g. Line 1 - PO 1 - Qty 2 ::: Line 2 - PO 2 - Qty 3), the agent is not able to create the ASN and is failing with validation errors

Trying to understand if this is the expected behavior of this seeded agent?
