Picking Area in EWM +S4hana Embedded

Dear Team,

We are implementing Embedded EWM(1909) to a customer. Currently they are using ECC-WM.

In the current system some processes related to putaway and RF queue determination (both standard +custom logic) is based on "Picking Area". And client wanted to leverage the picking area functionality in EWM too. Its critical for them

They want to see this field(Picking area) in bin master too.

As we know there is no picking area in EWM.

Can someone suggest me the best approach for this, hope we cant leverage the activity area.

Regards,

Hari.
