Hi Ashwini,
Does you have Yearly distribution of thr budget. Error Message no. BQ008 refers to there is difference between the Overall and Yearly Budget.
Message refers to total of yearly budget for the WBS is more than Overall Budget. Kindly check the Cumulative value in CJ31.
if you are reducing Overall budget you need to reduce Yearly too. Please Maintain Financial year in CJ34 for reference and Tick Overall Too.
