Identification of Parent and Child WBS elements at Table level

Hello Friends,

We are building a new report based on the table RPSCO for getting the overall budget values for WBS elements. we are filtering based on the value type 41 in the table. Our report works well for child WBS elements and the overall budget value is picked up correctly and it is matching with the values in S_ALR_87013558 report. But for the Parent WBS elements the values in RPSCO table sums up to 0.00 whereas in the S_ALR_87013558 report all the child values are summed up and displayed at Parent level.

How do we identify whether a wbs element contains child or not through the tables?

Any inputs on this is highly appreciated.

Regards

Surya
