Adding 0MAT_PLANT to a multiprovider to use its attribute

Dear Guru's,

I have a multi provider created on 5 cubes. Of there 2 cubes have the characteristic 0MAT_PLANT added to their dimensions.Rest of the 3 cubes do not have it , but they have 0MATERIAL and 0PLANT in them .

I added 0MAT_PLANT in the multiprovider and run the query , and using one of its Navigational attributed 0MRP_TYPE in the query . I find not all the records have the 0MRP_TYPE shown. some show as # ( not assigned ).

I even tried to add info object 0MAT_PLANT as one f the info providers to the multi cube and assigned 0MAT_PLANT charavteristic to all the 2 cubes and 0MAT_PLANT . Even then not all vales for 0MRP_TYPE are shown . Kindly on advice how i can show mrp type in my query. All the info providers have live data .

Thanks in Advance.

Chanda.
