You might have faced the issue where the Material Out voucher is appearing in the Day Book, but does not appear in the Material Out Register. This may happen due to regrouping of the Voucher Type. To resolve this:
Gateway of Tally > Alter > type or select Voucher Type > and press Enter.
Alternatively, press Alt+G (Go To) > Alter Master > type or select Voucher Type > and press Enter.
Select Material Out.
Set the option Use for Job Work to Yes.
Press Ctrl+A to accept.
By enabling the option Use for Job Work, all the transactions of Job Work recorded in Material Out voucher type will be displayed in the Material Out Register.
Note: If you have already recorded a transaction in the Material Out voucher type, you cannot enable this option. Hence, you need to create a new voucher type under Material Out voucher type, enable the option Use for job work, and record the same transactions in this new voucher type.
