Assign a material to an existing Storage Location

Hi,

I had missed to assign a material to a storage location while creating it. As of now, the material is not assigned to any storage location. How do I assign an existing storage location to this material?

Points to Note:

I tried MMSC, but I get the message 'Plant XXXX does not have maint. status DL'

I am not able to assign a storage location to the material through MM02 as well.

This material has not been produced as yet. I got a warning message about the non-existent storage location while creating the first planned order.

Could anyone please help me out with this? Thanks!
