Would seem I had an empty guid that i never used.. and I can get round that no problem... but I have hit another snag 🙁

When I try and insert the value I get

The INSERT statement conflicted with the CHECK constraint "repl_identity_range_D15CCC90_AB85_424C_8043_093A8B1625FF". The conflict occurred in database "GSPRO", table "dbo.tbl_asn", column 'asn_id'.

Due to managed identity range.. is there anyway to get round this?
