While posting an invoice, I got the error msg "item... of WBS elementXXXX...exceeding budget". I went to CJ30 to increase the budget. There I can increase the budget of the WBS element for invidual years, NOT the overall budget. When I am trying to increase the budget for individual years, I am getting stopped by "overall budget value < total new budget value".
I tried CJ36 and even CJ37 , but there also could not increase the overall budget.
