Dear Sanaa,
you are using the new ALV dashboard in the financial planning by Switch 0002 / 0012.
You can still use the old - standard view if you do not need this behaviour instead of the ALV view.
Or you can comment out the below mentioned line (as an enhancement):
Web Dynpro component '/RPM/FIN_CAP_PLANNING',
view - VI_PLANNING_ALV
Method - ALV_REFRESH_MODEL
Comment out the line 16
'wd_this->alv_refresh_model_aggr_rules( ).'
Best regards,
Judith
