LedgerTrans table

Hello All,

When ever the lines are invoiced in the SalesLine, there are lines inserted in the LedgerTrans table. I wanted to know how are these lines inserted. I know that SalesFormLetter class is used for invoicing the SalesLine, but when and how are the lines inserted in the LedgerTrans. Is there any map used or something like that.

Thanks in advance.

Regards,

Saurabh
