Can I use Savable Data Pages multiple times in a Flow?

Yes.

Add the Save Data Page automation wherever a save a Data Page should be triggered in Flows.

Note however that if the Save operation fails, this will result in the FlowProblems path for the case type being triggered. This may be the desired outcome if a task should be assigned to a person or team to troubleshoot and resolve the failure.

If the intended behavior is to revert back to prevent the current process step from completing, add the Savable Data Page to the relevant Flow Action that must be blocked if the Save fails.

Discussion on this topic was sought from the LSA Data Excellence (Pega 8.4) webinar conducted in July 2020. The webinar and its full set of discussions that arose from it are available at LSA Data Excellence: Webinar, Questions & Answers.
