Tally entry doubt -reg.

Dear frds/ experts,

In a case, a small manufacturing industry is manufacturing 'spooled coir yarn' using the raw material 'fibre'. For that they purchase fibre as raw material and after production they convert it into spooled coir yarn and sell them. Now coming to the point, how to make tally entries for 1)purchase of fibre, 2) spooled Coir yarn' sales 3)conversion of raw material into finished product and 4) for loss or wastage of raw material during production.

plz treat urgent and earliest reply would be greatly appreciated.

Thanks in adv / Maya.
