Validation of non-qualifier

Question

Hello experts
I have a validation problem on my qualified table.
From the main table, containing customers I have a qualifier called Customer Numbers. It only has one non-qualifier called organization. It represents the internal organisation at the company and a customer can have different customer numbers depending on the organization.
Organizations can be: Org A, Org B etc.
Customer number is a text field.
Other qualifiers exist but they are not important for the validation.
I need to make sure that all customer numbers that are created have a text field that is not blank.
I can get it to work if there is only one qualified link but if I have several I'm not able to get a consistent satisfactory result.
This is an ok example:
Organization   Customer Number    Other data
Org A          12345              XYZ
Org B          67890              XYZ
Org A          67890              XYZ
This is not allowed since the customer number for org B is blank:
Organization   Customer Number    Other data
Org A          12345              XYZ
Org B                             XYZ
Org A          67890              XYZ
I have looked at [this thread|Validation Help; without luck.
I have also tried the HAS_ANY_VALUES() function but it doesn't seem to work with IS_NOT_NULL. Any help would be appreciated.

One thing to consider here is that the semantics of IS_NULL and IS_NOT_NULL have changed in MDM 5.5 SP06 (see page 4 of the release notes: https://service.sap.com/~sapidb/011000358700001124542007E ). Therefore, the correct implementation depends on the MDM version you're using. If it's below SP06, you'll have to keep in mind to change the validation expression during an upgrade. If you're using SP06 (or already MDM 7.1), Udya's advice to use IS_NULL resp. IS_NOT_NULL should be the better way to go.
