SAP is picking profit center from material master instead of WBS

Hello

I am posting one GRN posting for a project specific procurement. But while checking the accounting entry of GRN , I found that for inventory account system has taken profit centre from WBS but for GR / IR clearing account, it has taken profit center from material master instead of profit centre from WBS. Is this a standard behavior of SAP system ?

Can any help in this matter. How to correct this ?

Thanks & Best Regards
