Reference Qualifier on Lookup Select Box Variable

Blair5 · ‎03-02-2015

I've been looking through the WIKI/community and it seems like there is a bug with reference qualifiers on Lookup Select box variables. Does anyone know if there is a work around besides making the field a reference variable?

I have 3 variables on a form -- each dependent on the last. The first is a lookup select box and I'd like the second to be a lookup select box with a reference qualifier because setting it as a reference variable gives the same information as the third variable. I've tried only showing the columns I want (with attributes), but it still shows too much.

Is there another angle I can take? Building the list with a script? I only want to show unique values. Any ideas/help would be greatly appreciated because I think I've exhausted all the options I can think of. Thanks!

Seems like we all have been trolled here Look up select supports reference qualifier but it's not simple as reference field..

Check the wiki page

http://wiki.servicenow.com/index.php?title=Variable_Types#Lookup_Select_Box

We need to use 'ref_qual_elements' attribute to get the updated reference working..

I am able to do the dynamic thing working after adding the attribute...

Sample demo:

Create 2 lookup select variable called 'located_at' and 'user' referring location and user table respectively.

Idea here is to display the user depending on the location selected...

In the user variable, define reference qual as javascript: 'location='+current.variables.located_at; and variable attribute as ref_qual_elements=located_at

This will make the variable to use the updated reference. Try this out and let me know if this works for you as well.

Note: I tried on Fuji instance.

Now you need to help yourself and try to find where the problem is

Kalai,

That worked perfectly -- having a reference makes things so much easier! Thank you for taking the time to do this.
