Normally I would check the Workflow Settings page. If it's a reusable, then there should be a disabled Content Types setting showing which content type the workflow is intended for. And reusable workflows are created via the same Nintex menu where you also create Site workflows..
I've checked and can't see the Content Types setting. What I can see is below. I clicked on Association Columns, added a Test column and it showed up in the Set Drop down in the Set Field Value action.
Yes, but that will add a new column to your list as well. Unless that is what you want. And what if you try to use Update Item instead? Using the list and filter on ID = Lookup/Current Item/ID? would that allow you to see the fields?
@jpmhuls I have a reusable site collection workflow based on all content type, the only value that I can check is "Content type", it does not show me the user defined fields that I have created for each of the content type. I need the reusable workflow to detect if the "Approver" field in my content type has any value before proceeding to sending an email to the Approver. Wonder how do I get the user defined fields to show up in reusable site collection workflows?
Do you have proper permissions on the library?
NB: If a column is hidden, it also wouldn't show in the list of available columns (most likely not the issue regarding here).
I have full rights to the doc library. I am able to see the list of fields belonging to the "current item" option when I create simple workflow, but unable to see this in the reusable workflow that is applying to all content type. Is this by design?
