In Fiori application, there is a persistence layer that uses caching mechanism. To begin every
troubleshooting session, recommendation is to “Always clear the cache”
– Clear Metadata Cache:
▫ Transaction /IWFND/CACHE_CLEANUP on Frontend Server
▫ Transaction /IWBEP/CACHE_CLEANUP on Backend Server
– Synchronize Chip Cache (Frontend):
▫ Run report: /UI2/CHIP_SYNCHRONIZE_CACHE

Starting in S/4HANA 1511 many Fiori Applications make use of Service Adaptation Definition Language
(SADL) based OData services in order to consume and expose CDS views
SADL models are entities that are used in business applications – for example, business objects, database
tables, search views.
A SADL model is a data model like:
▪ DDIC tables or views
▪ CDS
▪ BOPF
The authorization enforcement in this process is interposed between query specification by application or end
user and data retrieval from the database

Fiori TroubleshootingAuthorizations – CDS Views
40PUBLIC© 2021 SAP SE or an SAP affiliate company. All rights reserved. ǀ
The first step to troubleshoot an OData service
is to identify which objects will be consumed by
the service.
However, not all OData services are the same,
we can classify them depending on the
artifacts they consume:
➢ Enterprise Search
➢ CDS view
➢ ABAP
Depending on the objects that are being
consumed you will need to define the
troubleshooting path.

General Steps:
1. Make sure you are using a supported browser based on the backend system's SP level: Browser supporting
2. While running a debugging session, make sure the webdynpro content
calls are being redirected to the backend server. An important number of issues are caused by incorrect url dispatching.
3. Check the Common Issues, maybe it is already a known problem.
4. Run the webdynpro application without any outer framework (Portal, NWBC) and check if the issue persists that way.

3. Latest CL_HTTP_EXT_ITS
• The first point when an HTTP request meets the ITS layer is the ITS HTTP request handler, called CL_HTTP_EXT_ITS. This handler class is very important, because it is responsible to build ITS frameset. The ITS frameset handles session management, XSRF
protection, correct page sizing, parameter handling, rendering modes and more features.
• Newer versions of the class CL_HTTP_EXT_ITS are always delivered in the latest BASIS Support Packages (SAP_BASIS, SAPKB... or SAPK-...INSAPBASIS). But in certain cases it is also possible to apply correction instructions via transaction SNOTE for
this class. In order to use the latest version of the handler (CL_HTTP_EXT_ITS), please apply the appropriate SAP Note and all of its prerequisites.
4. Review ITS Service Configuration (GUI Configuration).
• Are the used GUI Parameters correct?
• Check ITS related profile parameters.
• Learn more about ITS feature flags: List of Features
5. Special Cases and Troubleshooting Tools
• If you believe, that all of the above are correct (i.e. latest kernel, latest handler and correct configuration), go trough the special cases and troubleshooting tools in the ITS Troubleshooting Guide.

1. Understand Landscape Architecture:
– Transactional Apps implement OData calls from the Frontend server but Webdynpro and Object Page
require a direct connection the Backend server.
– Hub Deployments: Several RFC connections are required.
▫ Firewall adjustments may be needed in complex network architectures.
2. Catalog Replication / Index Calculation:
– Set up Fiori Catalog Replication and Index Calculation jobs to run at least once a day, this will make sure
that Catalog and Application ID status is consistent.
▫ Report /UI5/APP_INDEX_CALCULATE
▫ Report /UI2/GET_APP_DESCR_REMOTE
3. Update UI libraries:
–Important corrections are delivered in UI libraries that will help stabilize Fiori apps.

4. Hub Deployments - One frontend for multiple backends:
– In this case, try to maintain 1 frontend client per backend client within the same landscape.
5. Hub Deployments - Security:
– Enabling trust relationship between the frontend and backend server requires all users to possess
authorization object: S_RFCACL
– Replication of user ID’s between frontend and backend clients is required.

Understanding the overall architecture of the solution is key to identify performance issues because
in the Fiori architecture, your browser is directly accessing the back-end via each Fiori tile. Each tile
on the FLP is making numerous calls to (and receiving) data from the server, which can cause
latency issues.
Note that when referring to the backends in the S/4HANA model we are talking about the
integration between 3 main components:
• Web Dispatcher
• Frontend Server
• Backend Server
Depending on the network configurations of these servers, network performance issues may arise.

Use what you need
✓ The more tiles you have on your FLP, the longer it will take to
load
✓ To lessen any latency issues, only add the tiles you need.
✓ It is recommended that you do not exceed 7x7 (49 tiles) per FLP
group, also notice the more catalogs you have assigned, the
longer it’s going to take to load the home screen.
✓ Go through Design Thinking workshops at the early stages of
the project in order to build “Personas” which will later help you
define the required business roles

All tiles are not equal
✓ KPI and dynamic tiles have a bigger impact on bandwidth,
as they are in constant communication with the back-end
servers to update.
✓ Static tiles do not change; once they are loaded onto the
FLP, they are not making any additional “calls” to update.
✓ For KPI and dynamic tiles try to define a refresh interval or
cache duration suitable to your end user needs and SAP
landscape capabilities.

Introducing Tab Bar Navigation
✓ This feature changes the interaction of the end user
with FLP as tiles are displayed per group.
✓ Can be switched on for all users by the system
administrator or enabled through user
personalization.

Improve Webdynpro, Webgui and App Finder performance
✓ Webdynpro, Webgui and App Finder → Check kernel version and try to update as this is
required by the new unified rendering concept.
✓ To load Webdynpro or Webgui apps FLP uses the NWBC runtime, it is recommended to update
NWBC runtime by implementing the following notes in order:
• 2408184
• 2405259
• 2433839
✓ Try running report /UI2/NWBC_DELETE_MENU_CACHE every now and then as you may find
wrong entries in table /UI2/NWBC_NAV_TR (column NWBC_VERSION will have the value
“LOADING”).

Improve Webdynpro, Webgui and App Finder performance - UPDATE
✓ As of August 25th, 2017 you no longer need to update the entire kernel package.
✓ A new package, called sapwebgui, is now delivered. It contains only the WEBGUI related files.
✓ If you have interest in this new approach, then you can find more information in
KBA 2221289 (How to install package sapwebgui).

Improve OData performance
✓ In some very specific cases you will find
that OData requests execution time is
longer than expected.
✓ This will usually occur for OData services
that expose very large data sets. If this is
the case, you can try configuring OData
services in Co-deployed mode.

Make sure your browser’s cache is
optimized
✓ Ensure your browser cache settings are optimized for
maximum performance and try not to use any settings
that bypass the browser cache:
• Do not run the Fiori Launchpad in private mode
• Select a sufficient cache size limit
• Do not clear the cache history automatically when the browser closes
• Enable browser caching
• Do not disable the browser cache in the browser developer tools
• Enable HTTP compression
✓ You can find a detailed how-to document describing
these settings in all three major browsers (Chrome,
Firefox, Internet Explorer) in note 2447857

Get the right Certificates (HTTPS)
✓ Make sure HTTPS connectivity is correctly setup.
Monitor this in the browser’s dev tools – network tab.
✓ If you are using self-signed certificates or your
certificate has not been signed by a valid Certificate
Authority (CA) you will face performance issues as any
error with the certificate means that the webpage will
not be loaded. You can find additional details here and
here.
✓ Note that versions 58 or higher of Chrome now
mandatorily require that the SAN (Subject Alternative
Name) field of the server’s SSL certificate is correctly
populated, you’ll find the detailed issue and resolution
in this blog.
