Movement Type's in EWM

Hi EWM Guru's,

We need your advice asap on the following:

Due to recent migration , cutover and archiving and also hard ware issue's.
our SCM system have lot of stock difference's in between ECC and SCM.

We have performed inventory sync in between ECC and SCM to match the stock difference's in between both system's. But we have performed this activity many time's.

Now finance team is having issue's with inventory sync as account;s are affected.

So they requested a seperate movement type to use when ever we sync the stock with /SCWM/ERP_STOCKCHECK . now whenever we sync they will get 711 and 712.

But finance team need a seperate movement type 9** to do the inventory sync whenever we see a huge difference of stock's in between ecc and scm.

Please advice this can be achieved from configuration or we have to do custom development.

Thanks

Vy
