Error in insert into the vendor table

When i insert into vendor table shows an error


Microsoft Dynamics NAV

Vendor 000001 already has a Contact Business Relation with Contact CON0005735.

OK

I also delete the contact no = ‘CON0005735’ in Contact Business RelationShip table.

When i insert shows an error.

Thanks.

How are you deleting the records? How are you inserting the records?

What records exist in the business relationship tables and are you deleting these?
