I am using Dynamics NAV 2016.  Is it possible to create a validation rule that allows you to exclude more than one item?  I cannot get it to work for more than one vendor. 

Validation Rule:

Criteria Lines:


PROGRAM    1310


Rule Lines:

ENROLL NO   M0001..M0009

Objective:  When a requisition is created using the G/L Account and Program number identified, we want the user to always include the enrollment number.  However, for two separate vendors no enrollment number is required.
