Error occured during budget check while planning in network activity

Dear All,

i have created a project with 4 WBSE. i have assigned budget to one of these WBSE and released that project. than i want to do planning in next WBSE this is giving error while saving this planning as Error occured during budget check, see cost.

i have created user status for budgeting like if we have not budgeted than WBS is not able to release. i have added availability control as Forbidden while not budgeted but this not effective.

please suggest me some thing to remove this problem

thanks

Sunil
