Trying to update a field on a case record when the user creates an estimate from the related records. The WF attempts to set the value but throws this error:

Value cannot be set in BEFORELOAD on already existing (not a new) record.

I can only set the field if it runs on After Submit, but do not want to save the case to run the WF. None of the other triggers work. Any way around this?

Not with workflow.

Damn it. Thanks for confirming.
