I'm working with a client org that uses the Field Service Lightning managed package. FSL includes a few fieldsets we can edit in order to make sure certain fields show on certain pages.

The FSL Service object has one such fieldset called Service Lightbox. When I go to edit the fieldset, I see a whole bunch of my custom fields and many of the fields that came with FSL. I am able to add fields pointing to related objects such as Account, Asset and Resource. However for whatever reason the related Contact does not appear as an option. For a different FSL fieldset, Services List Columns, there is no such issue and I'm indeed able to add Contact to the fieldset. Similarly if I create my own fieldset I can add Contact to it.

Is there anything I'm missing here? What drives the available fields I can choose to add to a fieldset? It really is essential to add Contact here and it does not make sense that it's unavailable.

  • Bump? I really never figured this out and it's really irritating me.

Field sets in managed packages require the developer to explicitly mark each one as eligible to be added to the field set. https://salesforce.stackexchange.com/a/63416/55332

There is an idea to be able to set this at the object level, since many managed package owners overlook this. https://success.salesforce.com/ideaView?id=08730000000aKz1AAE
