How to change one of the fields in the infoset

Hi,

I created a query and infoset using sq01,sq02 transaction i have Cost Center field in the query that is pointing to P0001-KOSTL.

when i execute the query by giving the cost center criteria ,query is getting executed on the Local Cost Center .But i want that to be executed on Global Cost Center.

Does Cost Center point to Local Cost Center only.How will I change it to point to Global Cost Center

Thanks
