Treasury Money Market Rollover Accounting entry should not generate

Hi,

1) While doing Treasury Money Market Transaction Rollover, its generating 2 accounting entries when I perform TBB1.

a)       Dr. Fixed Deposit GL xxxxx

           Cr  Outgoing Bank Account xxxxx

b)       Dr Incoming Bank xxx

          Cr Interest-Fixed Deposit xxx

issue is a) first accounting entry not required, it should not be generated, when I do initial placement its already updated Dr Fixed Deposit GL, when I do rollover only its required 2nd entry(Interest), how to restrict 1st entry for rollover? how to derive FUND for Interest GL its asking, its not populating field anywhere to enter. where can I setup fund for revenue GLs?

Appreciate if any one advise my issue. Thanks..

Regards
