Issue in adding a child line with an update operation, when another child line already exists.

Summary:

We are doing an re-implementation from OTM 6.4.1 to 6.5.2. We have a specific scenario where the XML doesn't work the way it is expected to. When we have a parent line and we add a Child line to it, it works as expected, but when we try to add another child line to the same parent Line, the ParentTransactionLineGid doesn't get recorded in the base tables; and hence appears as another parent line.

This issue doesn't occur in OTM 6.4.1. If anyone has faced a similar issue, would appreciate if you could share your feedback/learnings on this.
