    Update MSLStore1_Products set ExternalCoode = right(MSLStore1_Products.productcode, len(MSLStore1_Products.productcode) - LEN(supplier.prefix) )
From 
MSLStore1_Products , supplier WHERE MSLStore1_Products.suppid = 9217 AND MSLStore1_Products.SgpID = 123 and supplier.supno = MSLStore1_Products.suppid

    I have always been caught out by aliases in joins in updates (because I don’t think you can alias the target of the update), which is why I replaced the aliases with full names.
