gst purchase

You can make entry as purchase from composition @ taxrate%.

sir plz details information in hindi

Dont know hindi.

Simply amount of purchase bina gst input k, goods debit, supplier credit

Create a ledger in tally with purchase from composition dealer @ tax% either 5 or 12 or 18 or 28 which ever is applicable and pass the purchase entry.

No need when I define in suppliers master the status of supplier then why we need of creating separate ledger.

You have to create separate ledger to bifuricate regular purchase and composition purchase.
Regular purchase have ITC(gst) and composition purchase has no gst.

But from purchase register you can find or from gstr reports

You will find the all purchase bill in purchase register.
For example. If there are 100 invoices, 2 bills are composition bill.
How will you identity the particular bill?
If you have created separate ledger like local purchase, inter state purchase, URD purchase and composition purchase- you can identify the particular transactions.
I think now you got it.......

Agreed with Shri Vinod Babu..
