Ability to Consolidate Multiple Shipment Lines into a Single AR Invoice Line for Transfer Orders SFO

Description:
Currently, in the SFO process for Transfer Orders, it is not possible to consolidate multiple shipment lines into a single AR invoice line. The system only allows grouping at the invoice header level, but each shipment line is always converted into a separate invoice line in AR.

This limitation results in:

Higher number of invoice lines than required

Increased complexity in invoice review and reconciliation

Additional downstream processing effort for Finance and Business teams

Proposed Enhancement:
Introduce functionality that allows multiple shipment lines under the same Transfer Order to be grouped into one AR invoice line, similar to the flexibility available in Sales Orders. This will simplify invoice structures, improve usability, and reduce manual effort.
