2825187 - Unable to access oData Services or API of S/4HANA Public Cloud in Browser

Facing error while trying to access any oData services of S4HANA Cloud system from the browsers like Chrome, Firefox or Internet Explorer. Sample OData Service: https://myXXXXX-api.s4hana.ondemand.com/sap/opu/odata/sap/YY1_MATERIAL_STOCK_CDS

Possible Errors:

• SAML2 service not accessible.
• Asking for credentials when you open URL in browser.

S/4HANA Public Cloud (all versions)

This is caused to due to conflict with SCI or other SAML authentication systems configured in your SAP Cloud systems. Cache saved in your browser for SAML or other authentication causes these errors.

To avoid this issue, you need to follow below mentioned steps:

1. It’s best to open a new Browser Window in incognito/private mode, so we don’t use any existing session or conflict with any other authentication methods.
2. This API or oDATA service call needed to login via the Communication User you have created while setup of your communication arrangement.
3. Enter the URL from the last step and it’s typically helpful to add the “?saml2=disabled” parameter to the URL, to avoid any issues with SCI or other SAML authentication systems as mentioned earlier. It’s also important that you click Cancel in any type of Certification Selection Dialog.
4. This should bring up an Authentication Dialog where you can enter the credentials from the Communication User you have created.
5. If everything works you should get an overview about the objects in our oDATA service.

Here you just have one Object. Need to find the href parameter for that Object and add it to the URL. With the extended URL trigger the browser again and might have to wait for a bit as the CDS view returns thousands of records. Usually the browser will show it nicely XML formatted (or also in JSON if you add parameter $format=json), if there are too many records.
