budget error in Project system

Hi All,

My overall budget is 100000 the project is been planned on the overall basis and not on annual basis

my assigned value in tcode Cj30 is 98000 so i have only 2000 remaining But in information system tcode s_alr_87013558 it is showing me that mine assigned value is only 70000 and remaining is 30000 but however i could not make any purchase req or any services activity even though i have 30000.

What is this Assigned Values is there any report for me to see this assigned values.

The solution which i did is in tcode cjbw i have deactivated the availability control for the project. Now the 30000 which was available it is absorbing and my problem is now solved but now this available budget is also going in minus values how can i stop this.

How Again can i Reactivate the availability control. In my budget profile (OPS9) i have put availability control status as 1 (activate at the time of budget allocation)

ASSURED OF REWARD POINTS IF FIND USEFUL.

Regards,

Abraham
