Is it possible to display Custom Application Logs in S/4HANA Cloud Public Edition?

[DiegoValdivia]

Hi everyone,

Today i implemented some ABAP Restful Event handling.

As part of the logic, I save some messages in the system using class CL_BALI_LOG which creates Application Logs, just like we used to do with BAL_LOG Function Modules.

The Log logic works great, I’m allowed to save the logs correctly.

The problem I’m facing is that I haven’t found a way to Display those custom logs using a Fiori app in Cloud Public using a standard Fiori App. In On-Premise systems, we display them using tcode SLG1.

Here is the list of my findings:

• SAP Help page https://help.sap.com/docs/SAP_S4HANA_CLOUD/a630d57fc5004c6383e7a81efee7a8bb/a64ed2759f274871ab279ca0... is very vague regarding Application Logs app. It just mentions some Tile, but doesn’t specify the Business Catalog that contains such Tile
• 
• I found app “F1487 Application Logs” in the Fiori Library https://fioriappslibrary.hana.ondemand.com/sap/fix/externalViewer/#/detail/Apps('F1487')/S34 , but if I search for app F1487 in the IAM Information System, such app doesn’t exist in any Business Catalog
• 
• I tried to use the Custom Tiles app to create a Tile that points to the same intent of
• app “F1487 Application Logs” but I got some error message, because of the lack of authorization. I'm aware this app was designed to call external links, but it was worth the try
  
• 

• The only way I have found so far to display the logs is by executing a custom Class CL_BALI_LOG_DB. I could create a CDS Custom Entity, for sure, but I’m trying to find a more standard way.

• There’s a last alternative mentioned in this link https://help.sap.com/docs/SAP_S4HANA_CLOUD/6aa39f1ac05441e5a23f484f31e477e7/f0fdb1a176704bf6a18b14aa... .I could create a Freestyle app and add the Reuse Library, but my previous experience with Reuse Libraries was not good.

Please let me know if you have any suggestions or if you have accomplish Log Display in a different way.

Hi DiegoValdivia, I have the same requirement both for creating the log in RAP and displaying it in the application. Were you able to solve it? Thanks in advance.

Hi @Danii

The only way I found for the users to access the logs was to create a Custom Entity with a custom class that reads the logs using class CL_BALI_LOG_DB. I added a couple of annotations to the custom entity and created a UI Service Binding. Unfortunately, I couldn't test further since my client doesn't want to pay for Business Application Studio, because he says this should be a functionality included by SAP. And I agree with him.

Hi Diego, thanks for replying so quickly. I also agree that this should be included by SAP. Regarding the first part you mentioned that you were able to do, if possible, could you elaborate a bit more? I’ve only recently started working with SAP Cloud, and any information I can get is really helpful.

Hi @Daniii I suggest for you to read the full section of SAP Help related to Application Logs, as well as implementing the code snippets provided there:

https://help.sap.com/docs/btp/sap-business-technology-platform/read-application-logs-from-database 

Once you make them work for your scenario. Then you need to implement a Custom Entity with a Class that reads the logs using the logic you created in the step above. I suggest for you to follow next tutorial https://developers.sap.com/tutorials/abap-environment-a4c-create-custom-entity.html There are plenty helpful tutorials about Custom Entities, in case you need additional information.

I hope this helps.

Hi Diego, thank you very much for all the information. I have been reviewing it, and it really helps me understand how to get started.

Hello,

Thank you very much for your question and sorry for the late reply.

Can you please check whether the following information (GenAI was used to help generate this content) solves your issue?

To display custom application logs in SAP S/4HANA Cloud using a standard Fiori app, you can consider the following options:

1. SAP Fiori App ‘Display Application Logs’ (F1487): Manage Your SAP S/4HANA Cloud Public Edition - Application Logs

   • This app is designed to display application logs and is available in the SAP Fiori Library. However, you mentioned difficulties in finding it within the IAM Information System. Ensure that the app is included in the correct business catalog and that you have the necessary authorizations.

2. Freestyle App Integration: Developer Extensibility - Freestyle App Integration

   • You can create a freestyle app and integrate the application log display using the Fiori Reuse Library. This involves adapting your view definition and controller files to include the log display component. Although you have had challenges with reuse libraries before, this method provides a structured way to display logs.

3. Custom Class CL_BALI_LOG_DB:

   • As you have already implemented, using a custom class to retrieve and display logs is a viable option. You can enhance this approach by creating a CDS Custom Entity to expose the logs in a more structured format.

4. Creating a Custom Tile:

   • You attempted to create a custom tile pointing to the F1487 app intent. Ensure that you have the necessary authorizations and that the tile configuration is correct.

5. Business Catalog and Authorization:

   • Verify the business catalog that contains the application logs tile and ensure that your user role includes this catalog. You may need to consult with your system administrator to adjust roles and authorizations.

For more detailed guidance on implementing the Fiori Reuse Library, you can refer to the documentation on Freestyle App Integration.

Kind regards,

Henrike

Hi @HenrikeGrtecke even when I'm pro AI, I think it shouldn't be used for all scenarios, like the one in this post. This AI reply basically just reprhased my post and made it look like a response.
