Im very new to Power Apps (Literally a few weeks in). I have an issue that I may well be able to resolve but I am struggling with the basic fundamental concept.
I have built a Mobile Power App that will serve "on the road" engineering teams to support a few Govt systems. The app is to provide quite a lot of information for engineers that will assist them in understanding site configs and set ups etc. The sharepoint list that provides the App data source consists of around 25 columns of different types and I have these presenting within the app and engineers can update existing data (Updating the SP list) or create new entries (Not a very common thing) BUT, we have a lot of engineers and it is unlikely that the same engineer would only ever service certain locations and so I am trying to ensure that an engineer will provide issue and resolution details during their visit (In a collection) so that when a subsequent engineer visits during a future incident, the app will provide the history captured in the collection.
Im quite sure I have that bit working, but that data is not going back to the data source (Because I don't have anywhere for it). I am thinking I would like to add the accumulating collection data into a single SP column so that it is available elsewhere but is this the right approach (Or even possible) or should the collection data inform a separate list then called onLoad when the application is opened (Or the gallery item selected).
Ive looked through the forum throughout the day and can see various similar but ultimately different solutions but none provide any form of a conceptual overview.
