Double counting in MMBE totaling after using transaction MB1B movement type

Hi Friends,

I encounter the Problem " Double counting in MMBE totaling after using transaction MB1B movement type 411K "

The Problem Description:

Material: 0010-0050-3040.

P001 9000 shows Available Stock of 15,075 but actual physical QTY is only 7150, as highlighted in red circle.

Initial stock is zero. Immediately after MB1B 411K transactions of 7925 dated 12/04, we saw exactly double the figure of 7925, which is 15,850.

We believe the 15,075 (what we capture today) is after counting the issuance of 775 on 12/06.

Will this cause incorrect WM stock to be pick up when we transact using MIGO issuance?

This problem also occurs for material 0010-0050-3050.

Pls help me in this issue

Thanks
