I have a requirement to pull data from two data sources. Source B is dependent on source A. I look for data in source A first, it is not present, I need to look for it again in 8 hours, I repeat this for 48 hours (6 times) or until the data is found. Then I pull for data source B, which static, non-transactional data and I always present.
Is there a mechanism in WM IS 4.6, accessible from within a flow service, that can be used to schedule a task that will execute and upon failure try again at some interval and terminate either upon status of success or exhaustion of re-tries? Also, I need this “task/service” to be persisted, such that after an unplanned termination of the server, this service would restart and restore state to pick up where it left off. I know this sound very similar to Reliable Delivery in TN i.e. TASKS, but I don’t know of a way to achieve similar functionality from within a flow service. Any ideas?
