Material backflush in production order after finished goods GR

Question

Dear all,
I once started similiar topic several months ago, but didn't recieved any response. I'm gonna give it another try, so maybe you'll be able to support me after all.
So, the situation is like this. We have a production order, in which MC team maintained the materials to consume. The problem is, that very often it comes that we have to use same material part, but under 2-3 different partnumbers. E.G.:
Production order target: 1000 finished goods
Required materials: Part A 1000 pcs, Part B1 700 pcs, Part B2 300 pcs, Part C 1000 pcs, Part D1 150 pcs, Part D2 450 pcs, Part D3 400 pcs.
So yes, in case when it is Part B1, B2 and etc. it means that we're using physically the same part, but under different partnumbers. The problem is, that those material are all coming in pieces, not in meters or anything, and we can't allow to have, for example, 0.7 pcs of any of those materials (cause obviously you can't have 0.7 pcs of LCD panels stored in the warehouse).
It wouldn't be a problem if we could just confirm all operations in production order in 1 batch, but production order is being confirmed partially, every time the pallet with finished goods is being released from production line (we have integrated system, that sends requests to SAP to confirm specific quantity of finished goods in production order). So, as an example, if 1 pallet contains 15 pcs of finished goods, you have 67 confirmations for production order [(66*15)+(1*10)]. And, since all those materials come in PCS, SAP is rounding up consumption if it has decimal, which leads to wrong materials consumption.
Initially, I had an idea of adding 1 more operation in production order, which was supposed to be a manual use only, after finished goods GR, and MC team supposed to assign those B1\B2 and etc. material to this operation  E.G.:
Operation 0010 - consume material from work center A
Operation 0020 - consume material from work center B
Operation 0030 - finished goods GR (milestone)
Operation 0040 - consume material from work center C
My idead was rejected, since I was told that after GR for finished goods is done and you continue consuming materials in production order - it will not be shown in financial reporting (don't know the details, it was quite a straight reject, without much explanation).
So, question is - is there a way to consume materials after finished goods GR without creating mess in financial reporting, or if not - what other options do I have?
thank you in advance

Hi Valentin,
After GR also you can do goods issue. Till the order status is CLSD (Closed) you can book cost on to the order.
Two ways to consume materials on order.
In order component overview maintain the required part number with quantity. GI as can done with reference to order MB1A 261 movement type.
Directly do GI with MB1A -261 movement type - Input the order number, material number and qty.
Refer to the below discussion on unplanned GI which was discussed yesterday,
