Component Storage location getting defaulted in production order

Hi,

I am creating a Producn order, in which there are 5 comp.

All the 5 comp. are getting defaulted with stor locn 2001. Whereas what is maintained in Material master is 5001.

But in the production order the Components are getting defaulted with 2001 Stor Locn.

How can i remove the default.

Note: No BADI's or any user exit are applied.

Thanks in advance,

Harris
