It will be complicated to setup, but the (relatively) easy avenue that I can think of would be to use this, unsupported, tool Qlik Sense Partial Reload for v2.0.x, v2.1.1, v3.x on an EDX task which is dependent on the successful reload of the QV task.
This is of course a potentially easy method of calling the relevant APIs, e.g. https://help.qlik.com/en-US/sense-developer/2.2/Subsystems/RepositoryServiceAPI/Content/RepositoryServiceAPI/RepositoryS… & https://help.qlik.com/en-US/sense-developer/2.2/Subsystems/EngineAPI/Content/CreatingAppLoadingData/LoadData/reload-app.… which can be custom built out to your specifications with a bit of development work.
Finally it is working!
We had some issues with the QlikView user account . Initially, We did not add the service account user from QlikView in the "content Admin role " from QlikSense Console. For that reason we were not able to execute our task in QlkSense using Publisher. Once we added the service account from QlikView as "content admin role" in QlikSense it worked out perfectly.
Thanks a lot, you made our day !
