I am using below query to get the Voucher information. Code: <ENVELOPE><HEADER><VERSION>1</VERSION><TALLYREQUEST>Export</TALLYREQUEST><TYPE>Collection</TYPE><ID>TestLedgerList</ID></HEADER><BODY><DESC><STATICVARIABLES><SVCURRENTCOMPANY>Demo</SVCURRENTCOMPANY></STATICVARIABLES><TDL><TDLMESSAGE><COLLECTION NAME='TestLedgerList' ISMODIFY='NO'><TYPE>Voucher</TYPE ><FETCH>*</FETCH></COLLECTION></TDLMESSAGE></TDL></DESC></BODY></ENVELOPE> But this will produce lots of tags. How to know the meaning of those tags. Any Documentation available regarding this tags?
