Breakdown Subassemblies

Hello, this is Carlos.

I would like to ask some guidance about Breakdown Subassemblies function in the MRP scenario Detail Tab.

In case of an Order Related Finished good A, that possess a Stock Related Subassembly B, when disabling the breakdown subassemblies function it only shows  item A. No display for item B.

1. Reading the explanation in the manual it seems B should not be broken-down but still showed as a subassembly in the MRP result (at least that is how I understand it) . However, I am only able to see A  in the results. Does it means that only  finished good A should be shown and this is the correct way to be displayed? Is the manual correct?

Scenario 1

Sales Order - breakdown subassembly tick ON

Scenario 2

Sales order - breakdown subassemblies tick OFF

2. When using forecast only, and disabling this function, it shows all items related to A and item B without being broken-down. Should this function work the same for Forecast as for Sales Orders? Is ok like this ? Or may this be a bug?

Scenario 3

Forecast - breakdown subassembly tick ON

Scenario 4

Forecast - breakdown subassembly tick OFF

Some help will be highly appreciated.

Thank you.
