MES - LPN Transactions with Incremental Backflush

Hi all!

I'm trying to use MES for Process Manufacturing, and I have a situation which requires user to inform the batch no, LPN no (the LPN is generate in advance), and the quantity.

The navigation is:

MES for Process Manufacturing → Incr Backflush
But here i can't assign LPN
There is something LPN Transactions in which

8 < LPN Transactions

-- 1 < Product Completion

----- 1 < Product Completion

This is the only function I figured that allows me to inform both LPN number and Batch No to perform the WIP Completion.

But I would like to perform also an Incremental Backflush. This way I'm only doing the WIP Completion and not doing WIP Issues.
