Error On adding Items on a Purchase requisition

On trying to add items on a purchase requisition am getting the error below , I had made changes on the purchtable form but even after deleting the changes the search doesnt work , someone Kindly help

You should be probably doing Compile forward of classes for which stack trace error message is being displayed here. Also you could use the Right click on object=> Restore option.

Hi Kumar

I have tried doing a full application compilation but am still getting the same error .

Okay. May be you should check with your developer on this. Also check if the Procurement Category listed out there is available or not in the system as sometimes this also creates problem.
