Why is there an error in my GST number when the billing is done in one state but the shipping is in another state?
If you are facing error in GST number when billing and shipping address is from
different state then you can follow the steps
1 Select sale type as IGST if the billing party belongs to other state
2 on the billing shipping box GST report basis option select as per party master
and mention the shipping party address and name over there
Ensure that the billing party GSTIN is validating and mentioned properly
