My inbox FIORI Application. Error

[marina_sarkisyan]

Hello experts,

I'm trying to launch fiori application "my inbox" on S/4HANA on-premise 1511 FP01.

I activated oData service, UI5 component and assigned catalogues to my role (We have back-end and front-end on the same server), but I wasn't able to assign the role /IWPGW/RT_WF_USR (from fioriappslibrary) to my user, cause i doesnt' exist.

But I assigned all roles that contained any mention to WF to my user, just to be sure.

So when I tried to launch this application, I get the following error:

{"error":{"code":"SY/530","message":{"lang":"en","value":"An exception was raised."},"innererror":{"application":{"component_id":"OPU-BSC-TGW","service_namespace":"/IWPGW/","service_id":"TASKPROCESSING","service_version":"0002"},"transactionid":"6341F8E55038F19680BC0050569C4DE4","timestamp":"20160401193907.9920000","Error_Resolution":{"SAP_Transaction":"Run transaction /IWFND/ERROR_LOG on SAP Gateway hub system and search for entries with the timestamp above for more details","SAP_Note":"See SAP Note 1797736 for error analysis (https://service.sap.com/sap/support/notes/1797736)"},"errordetails":[{"code":"/IWBEP/CX_MGW_BOP_RFC_SYSTEM","message":"RFC call was not successful because of system failure 'Name or password is incorrect (repeat logon)'","propertyref":"","severity":"error","target":""},{"code":"/IWBEP/CX_MGW_TECH_EXCEPTION","message":"An exception was raised","propertyref":"","severity":"error","target":""}]}}}

In front-end error log I get the same confusing "An exeption was raised" with no explanation what's wrong...

And I have no idea what to do next and how to solve tat issue.

Did anyone faced the same problem? Please advise.

Thanks in advance,

Marina.

Hi Marina,

Did you create another system alias like BACK_PGW as in below image and added taskprocessing v2 service referring it ?

Hi Virinchy,

Yes I did. Here is a screenshot of my system aliases:

Is your TaskProcessing v2 service also referring to BACK_PGW system alias now ?

[marina_sarkisyan · Accepted solution]

Yes it does:

Well I reread the article from note 2244898 - Error: "Data Provider implementation 'ZTM_TGW_SVC_MODEL_0002_BE' '01' does not exist"() and since I have embedded deployment I changed my system aliases back to only Local one.

But I still get the eror (though a different one):

Please advise whats wrong...

Best wishes,

Marina

Hi Marina,

Please, check is installed component IW_PGW (NetWeaver Gateway Server)?

Best regards,

Konstantin

[marina_sarkisyan · Accepted solution]

Hi Konstantin,

Yes it is. Component version is 100

[Kostus · Accepted solution]

Could you try this:

1. Delete both versions of TaskProcessing service (delete at all)

2. Create from scratch just version 2.

Sometime ago I also have a such problems with Inbox. I don't remember quite well what error message I have but seems pretty similar to yours.

[marina_sarkisyan · Accepted solution]

I deleted both TASKPROCESSING services and created only the 2 version as you suggested.

But unfortunately nothing changed..Still get the error "Task Facade not omplemented for provider"

Hi Marina,

Take a look at discussions which had same error. SAP Search.

I think system alias definition is wrong.

Hi Masa,

First thing I did I looked into all that discussions. But nothing helped.

Well I did everything according that instruction: SAP Fiori LL18 - System Aliases definition for Fiori

As I said before, I have embedded deployment, so I have only LOCAL system alias so my TaskProcessing service refers to it..

I tried to create 2 special system aliases for IWPGW as the instruction said I might, but I ended up with the error I started this discussion with.

Could you please think of something else that could be wrong?

Thank you!

Please, check this setting in SPRO: SAP NetWeaver - SAP Gateway Service Enablement - Task Gateway - Registration - Provider Implementation:

Hi Marina,

My document says "BACK_PGW" and not "LOCAL".

"LOCAL" is for only UI2 services.

[marina_sarkisyan · Accepted solution]

Hi Masa,

well there is an entry for the embedded deployment in your document:

Embedded deployment is used often for sandbox test system.

If the landscape is Embedded deployment, everything goes to LOCAL.

So all my services goes to LOCAL

Isn't it correct?

Thanks

Hi Maria,

I recommend you to test with the document and confirm it. It can be done less than 10 min.

SAP Fiori LL18 - System Aliases definition for Fiori

After that you can play around by changing settings like LOCAL whatever you want to test.

Hi Masa

Thanks for your help. I found out that I made a mistake. Even since I defined System Aliases correctly (accotding to your document), I still chose LOCAL aliases while activating TASKPROCESSING service.

So thanks for support
