RFC Authorization Error in SAP WebIDE - No Authorization to log via a trusted system

[ahmed6141]

Hi Michal,

Need your expertise on this!

I know it could be a silly question to ask, but my developer gets as authorization issue when using a destination that was created with my user. it appears that I might not have authorization to log onto the back-end system via a trusted connection.

My question is, what should be the Authentication type used when connecting from SAP Cloud Platform to Back-end Systems?

Currently, we use 'Basic Authentication' as Authentication type but want to know what's the right one.

ask your developer to go to sm59 (frontend server)to check if they can logon to backend using the selected abap connection.

if I am not wrong, your user id is not used to access sap system.

yeah, I gave my user authorization to login via trusted RFC; now it works, but my user ID has to be always active i.e. unlocked, else Developers will not be able to use Destination with my user.

Hi Salman,

According to me When you set ProxyType to "OnPremise" then PrincipalPropagation is the most suitable authentication type.

Hi Meghal,

My developer still gets error when he tests his app, it prompts to enter his credentials but get error message as below(screenshot also attached)

Error Message "\{

"requestUri": "/sap/opu/odata/sap/ZRM_REQUEST_CR_SRV/$metadata?sap-documentation=heading&sap-language=en",
"statusCode": 200,
"statusText": "",
"headers": [],
"body": " UserUser PasswordPassword Log On Logon[\"SL__FORM\", \"SL__PAGE\"]"

The Destination in SAP Cloud Platform is defined with Authentication: PrincipalPropogation"

ProxyType: OnPremise

Any help is highly appreciated!

Thanks

Salman
