I wrote a flow that creates 4 Opportunities, then updates a field on each Opp (the update has to be a second step because I am storing the IDs of the created Opps to "pair" them up, so I don't have the Opp IDs until after the Create Records component is run).
My NPSP Opportunity Name settings display the related Opp I set in this field.
But the Opp name is generated by NPSP *before* I fill the field with Opp IDs, so it doesn't know about the "paired" Opp.
So after the Update Records component has run, I need to refresh the Opp names somehow from the flow.
Is there any sneaky way to accomplish this? Seems like it is not possible to call the NPSP bulk data process Refresh Opportunity Names, nor the single Refresh Name button, from a flow?
As you've discovered, NPSP only sets the opp name when you create the opp, not when you update it. You'll have to build your own opp renaming step + formula in your update process.
