Single-Unit Batches in EWM

Hello Experts,

i use the Single-Unit Batches in the material master data ERP Tcode MM02--> Additonal Data--> index tab 'Proportion/ prod.unit'--> field 'SU Btch Default Val. = 'C' Handeled in Single-Unit Batches.

For the Produktion Order i use material components with SU Batches. After releasing a Production Order we get an outbound delivery in EWM, but here is the problem:

The pick quantity in EWM is exactly the quantity from the BOM (bill of material CS03) in the Production Order (required amount 1m; physical stock of Batch is 6m -->Product unit 6m = 1EA).

In my opinion the complete batch should be picked here. We dont use the value in the checkbox 'Goods Iss. of Part. Quantities Allowed' (material master data--> Additonal Data--> index tab 'Proportion/ prod.unit')

Actually we handle the situation, while confirming the warehouse task, with Exception Handling.

Is there any way to pick the full SU Batch automatically despite the request quantity from the production Order?

Thanks in advanced.
