No... It's exactly wrong... We can show the Composition dealer purchase in Exempt / nil rated / Composition dealer purchase head. Not in B2B section....
@ Shah., I think you create dealer details without GSTIN...! So, you ll check it once and add the details like composition dealer then it show in Supplies received from 8. Supplies received from composition taxable person/unregistered person & other exempt/nil/non GST supplies
