Missing indexses in DB02

Hi ,

When i am monitoring the system thru DB02 i m getting missing secondary indexses.....can anyone tell me why they actually come? how severe can they for the system? how can i adjust them?

The name of the indexes are

/BIC/FITC_MDP-020

/BIC/FITC_MDP-030

/BIC/FITC_MDP-040

/BIC/FITC_MDP-050

/BIC/FITC_MDP-060

/BIC/FITC_MDP-070

and as a matter of fact i have run abap report

SAP_INFOCUBE_INDEXES_REPAIR

though running it has repaired some indexes but not the one i want.plz suggest
