Unable to create Item using item number generation rule based on EFF attribute values
We have a requirement to generate item number sequences for based on user defined attribute group values(Network Attributes), the EFF attribute 'Serial Type' has multiple values and for each value, we need to generate new sequence.
I created an item rule as below, it is validated successfully but, unable to create item(not able switch tabs in item creation form) by using user defined attribute group in item rule set. I've added this rule in master rule set in proper sequence, but still unable to create item only when we use user defined attribute groups.
The EFF attribute 'Serial Type' has no default value. The rule reference with this attribute have no value (also called a null value) are ignored. Expressions that evaluate to NULL are ignored.
