Flows triggered by other flows can be a little confusing. They need to be created in reverse order, but you should think forward in the process.
For App A, if you wish to update all related items in App B: - set up a Manual Flow with App B as the working app, triggered by App A - add an Action to this flow to update the item - then Create a Flow in App A to trigger this flow when relevant item fields are updated
For example: We have a Timesheets App (App A) and a Ticket App (App B). We have created a relationship field in the Timesheets App which referenced the Ticket App. The goal is to update a date field with the current date, whenever there is activity on the Ticket Item.
- First, set up a Manual Flow on the Tickets App, and triggered by the Timesheets App, to update the Last Activity Date field on the ticket.
Be sure to select where the app will be triggered, default is set to the Current App and will not run correctly when triggered from another app.
- Set up the flow that will trigger this Manual Flow on the Timesheets App.
