Error message setup for CJ32 3 level WBS elements

Dear all

We have 2 requirement for my project system as followed Below

1.The original budget inputted in CJ30 should be the same as released budget on 1st and 2nd WBS level

(i.e. value in column BUDGET is the same as the value in column RELEASE on each 1st and m2nd WBS level in CJ32 ):

2. No budget is released on 3rd WBS level (there must be zero in CJ32

need to set up the error message when entering the budget release in CJ32.

Hence requesting all please let me know is there any standard process available for above required

if not is there any validation or ABAP development possible.

If any validation is possible please let me the possible scenario.

and let me know the disadvatages for settings of error message if any

Thanks and Regards,

Jyothi Pasala.
