>>>It doesn't matter how you insert a record, but it matters what values you are going to use. I believe, that Tastrade uses PK-generated stored procedure value as default, and doesn't include this field in INSERT .... VALUES() list. I guess you can imitate the same thing with MEMVAR but you will have to specify that primary key field will not be included in the list.

I am setting the nextid function as the default value in table designer...
