Budget amount is differe with two different report for the same project and wbs

Hi,

I need your valuable input for the below my quires:

The total value of Budget column is differ with  below two different  report for the same project in production system.

1. 1.Report 1 :S_ALR_87013558 - Costs -> Budget-Related -> Budget/Actual/Commitment/Rem Plan/Assigned

2- Financials -> Costs -> Budget-Related -> Budget/Actual/Varianc

But if we compere the same two reports with  same project code in production copy system (all the business transaction remain same) total amount in

budget column  remain same.

is it standard  system behavior ? if not how to fix this issue.

Thanks in advance for your help
