POSDM Idocs post with batch

[former_member724566]

Hi Everybody,

I encounted a issue when implemented POSDM idoc type WPUUMS.

I have implemented Batch determination strategy and verify in IM and SD， and it is worked well in SAP front UI.

（in S4/HANA 1809）

But when I posted a idoc the batch determination can not be triggered as expected.

It seems have to click the button of stock determination and then do the batch spliting， and in MIGO different batch mapping a unique item row. Tt is not like in DN batch determination can be excuted really in backgroud.

So, as I searched in notes the enhancement segment E1WXX01 in message type WPUMMS should be implemented.

In Tcode WPUK， it is possible to input the segment E1WXX01， but I am not sure what information should be keyin.
It is very appreciated someone could give a practice sample.

By the way if the E1WXX01 was be filled ，what else job should be done such as configuration or BADI implemented .
