Hi Raju,
First of all, in Treasury module, all the things flows mostly automatic, like ICICI bank created as business partner. If they deduct TDS for one FD then why they don't deduct TDS for other. If in real time we will get this scenario, then just create 2 different business partner as ICICI w/wo TDS, system will create TDS & Non TDS flow automatically.
In case any further clarification, then revert.
