Budgeting

Dear PS Esperts,

Please tell me whether we can activate the Buget at the WBS level.

Means if I have 10 000 as the Value for a WBS then I can post only 10 000 but it should not take into acccount the entire buget (overall)

Say over all budget is 10 00 000 .

So i post f-02 with 20 000 for that particular WBS system should not allow ...Please tell me how to do the same.

regards,

A S
