Refer external object in formula field

Hi,

I have an external lookup in the Account object to an external object, I'm trying to get a value through this relationship
but I'm getting an error, is this possible? What I've tried is this:

ExternalObj__x.field

ExternalObj__r.field

externalLookupField__r.field

externalLookupField__x.field

 Any help would be appreciated it.

Thanks in advanced.

Hi,

Sorry for this issue you are facing.

You cannot refer external object fields in formula field. The following link gives you detailed limitations of external objects. However, I am not sure but you can write a trigger on the External object, which might probably help you.

External Data Integration Limits:
Do mark this as answer if it solves your problem.

Thanks,
