DEBIT NOTE - SEQUENCE

Dear Experts,

Debit note issued from buyer to seller – Purchase return (Eg: Material return, rate difference etc.)

Debit note issued from seller to buyer – Sales return (Eg: Material return, rate difference etc.)

In tally, Shall use common sequence for debit notes or we need to use separate sequence..?

If we use common sequence, there any problem in GST returns filling..?

Please clarify

Thanks & Regards
