Dear Mr. Ganapathy ,
First of all thanks for the reply.
what you have stated that is corrent but i think that the exact point which i want to know is missing , hence pls find an example below to clarify
" imagine that "X" Pvt.Ltd. is a steel manufacturer and registered under Company Act, Excise and Sales tax , thier major raw material is Steel scrap which they buys from registerd dealer under central excise and also from the dealer who is not registered under Central excise but under sales Tax and received invoices along with the material but some time or regulary basis they purchased from transient trader , who (transient trader) does not have any particular place of business and does not issue any invoice " so my query is in this kind of situation how to account purchses of raw material from transient trader for excise purpose and because transient trader never issue any invoice so we are no eligible for cenvat credit and according to me after process we have to pay excise duty on purchases of transient trader also. and pls explain recordds to maintin
