Steps to reporuce the issue -

New Instance

Add two internal locations under 'Physical Locations / Your Company / Stock' with defaults Physical Locations / Your Company / Stock / Finished Goods Physical Locations / Your Company / Stock / Raw Materials

Add a stock-able product A with the parameters below - Procurement Method: Make to Stock Supply Method: Manufacture Push Flow: from stock to Finished Goods, Automatic No Step Added

Add another stock-able product B with the parameters below - Procurement Method: Make to Stock Supply Method: buy Push Flow: from stock to Raw Materials, Automatic No Step Added

Define a bom A:B = 1:1

Enter and confirm a sales order of 100psc of A product and then run the scheduler.

A manufacturing order and a purchase order were generated.

Receive the purchase order of B products into warehouse

B product's stock by location looks like this -

Physical Locations / Your Company / Stock: 100 Physical Locations / Your Company / Stock / Raw Materials: 200 Partner Location / Suppliers: -100

Produce A to finish the MO

A product's stock by location looks like this -

Physical Locations / Your Company / Stock: 100 Physical Locations / Your Company / Stock / Finished Goods: 200 Virtual Location / Production: - 100

While checking A product's stock moves, we found two moves Virtual Location / Production --> Physical Locations / Your Company / Stock / Finished Goods: 100 Physical Locations / Your Company / Stock --> Physical Locations / Your Company / Stock / Finished Goods: 100

It's obvious that the 2nd move is unnecessary.
