186E

Field <field1> is required with <field2>

Reason:

You issued an insert or change command, and after all operands were processed it was determined that you are trying to use <field2>, without also having <field1> specified.

Note: This could be caused by trying to specify <field2> without <field1> being specified, or it could also be caused by trying to remove <field1> without also removing <field2>.

Action:

Issue the command again with the correct set of operands so that <field1> is specified, or so that <field2> is not.
