Automatic Posting of Consignment Stock - 411 K

Dear Friends,

We are on ECC 6 and I have been told that there is an option to carry out the stock posting from Consignment location to Unrestricted location (MB1B-411K) automatically when the sales posting happens.

Example :

That is when PO is created for consignment stock (Item category : K) and receipt is done the stock is in 0001 K location (Special Stock).

Now when sales posting is done then automatically system carries out stock movement of sold qty from 0001 K location to 0001 unrestricted location.

But currently this movement does not occur. Directly the stock is taken from 0001 K Location and is posted. Which is wrong as it does not create a credit entry for finished goods.

Could anyone please guide me on this automatic posting configuration ?

Regards

Govind
