Hi Singh,
as i understand , u knw the business flow as per client regarding Sub-Ledger i.e recon a/c should be updated automatically. wht happened, client want one Sub -GL account for Bonus Payable i.e Sundry Bonus Payable . in this recon gl whenever they do business transaction like provision for Bonus FY-2010, 11,12, it should be updated automatically . we knw that recon account can be Asset, Customer, Vendor and Contractors, but they want through GL recon type, in this case wht i did, i post the issues in SCN, Mr. Samapt has given an idea to resolve the issues.. according to him , Vendor can treat as Sundry Bonus GL. so i create Vendor a/c 100100 and assign here GL A/c 100400 Bonus Payable 2010-11, like that Bonus payable GL A/c No. 100401 for 2011-12, so, whenever you create GL Bonus Provision for Every year just create Vendor a/c i.e Sundry Bonus 100100 n given Recoon a/c 100400, 100401 like that.
thats it.
if u need any clarification , feel free to mail me.
Thanks
