Fiori App Error – “Could not open app. Try again later” :(

Dear All,

Now a days, SAP consultants are mostly concentrating on S/4 HANA Topics. As a functional Consultant, we could know at least basic’s on the Technical side of the S/4 HANA.

In this Blog, we are gonna see, Fiori App activation in Fiori Launchpad.

Example App: “Manage Buffer Levels”

App ID: F2706

Version : S/4 HANA 1709

Step 1:

Access Fiori Library

(‘F2706’)/S9OP )


Note Down the highlighted Path , OData Service, and Business Role (s)  specific to this Fiori App.


Step 2: Activate the service Path via T-code : SICF

Step 3: Activate the OData Services Via T-Code: /IWFND/MAINT_SERVICE

Before Activation, Please check whether OData Services available or not.


Incase, OData service not available, Please follow the below procedure.

Then Click , “Add selected Services”


OData Services has been added successfully :).


Step 4: Add the user ID to the Role

Logoff the Fiori Launchpad and Login Again.

Click on the Fiori App 🙂

      Hi Kumar,

      Thanks for your blog. It's always good to restate the basics and you have done that very clearly & concisely.

      As your aim is to guide newbies, it's important to point out that individual activation like this is ***not*** Best Practice for SAP S/4HANA, mostly because individual activation is extremely time consuming.  Also because you end up getting a lot of unwanted "Could not open app errors" because it's so easy to miss dependencies & other related apps when you activate ICF nodes and services one by one.

      Current best practice advice is to either:

      a) Use the Fiori Rapid Content Activation process as per SAP Note 2704570 - Composite SAP note: Rapid Activation for Fiori in S/4HANA 1809 or 2695653 - Composite SAP note: Rapid Activation for Fiori in S/4HANA 1709 depending on your release. 

      b) alternatively use transaction STC01 and the task lists described in Fiori for S/4HANA Basic Configuration with Task List or the UI Technologies guide for your version which can be found in the SAP Help Portal.

      Both of these approaches are much quicker than individual activation. They are also safer as you are less likely to miss dependencies such as reuse apps, especially if you make sure you select Related Apps and aggregate them as described in Adding Related Apps in the Fiori Apps Library.

      You can also find a lot more helpful blogs & other references on our public Fiori for S/4HANA wiki. If you are interested in writing more blogs then I would encourage you to check out what's already available

      Kind rgds

      It was very useful and practical. I could resolve an issue of not loading "Mass Maintenance of Products" loading error, with the procedure given here. O Data service was missing. Thank you very much.
