I am using the OData generator tool to create a simple query operation. However I keep on getting the below error when I try to consume in my web browser. Anyone seen this before?
Data Provider implementation 'Z_TIMESHEET_0001_PS' '01' '' does not exist
Z_TIMESHEET_0001_PS is the name of my gateway data model.
Can you go to transaction /spro (IMG) and check "SAP NetWeaver->Gateway->OData Channel->Configuration->Connection Settings->SAP NetWeaver Gateway to SAP Systems" and execute the Manage SAP System Aliases.
Make sure whatever SAP System Alias you are using where you are getting this error has at least the Software Version set. DEFAULT works in most cases.
Thanks for your response, I have changed the 'Software Version' to 'DEFAULT' and I am now getting a different error response.

I have created this service on SP02 on the generic channel and it works fine. However this is a new system and is on SP03 and I am using the OData channel.
Any other ideas would be much appreciated.
Have you looked in the error log of the gateway system? if not, execute your service call and then use transaction /IWFND/ERROR_LOG on the gateway system, it can provide you with much more information.
The error you receive is standard error returned in case of technical problem with the service. In the log you will find technical details and related error messages that can help you trace the problem.
Thanks for your response.
I am unfortunately not getting much detail from the error log but maybe you might recognise something.

I have one issue in Generating OData.
While generating gateway OData, I am facing the below error.
I am now using Demo version of SAP Netweaver gateway as Front
End and Development 300 as back End.
The following Error Message is occurring.
<message>Processing of request failed. Contact your system administrator</message>
I had gone through your conversation. But not clear with the solution available.
Pls do the needful.
Was this problem resolved?
I am having a problem in two different scenarios which look like it is equal to the original post.
I have created a simple odata service in the backend - a model class and a data runtime class with methods. Configuration tables for model and service have been maintained without errors.
In the Gateway system an odata service has been created with reference to a system alias and the sicf node is active.
But when I try to lauch Explorer I am getting this error:
/IWFND/MED/039 No service found for namespace /SAP/, name Z_BANK_MODELGRP_CLL, version 0001.
And when doing some more investigation in the error log I find the following errors:
Model 'Z_BANK_MODEL_CLL_0001_BE' contains errors. Contact Adminstrator
The same message is in the application log, together with other errors:
An exception has occurred
Exception of type /IWFND/CX_SODATA has occurred. See details for more information
Exception of type /IWCOR/CX_DS_INTERNAL_ERROR has occurred. See details for more information
If I try using the validation tool for the service I get this error:
An exception has occurred.
Gateway: NW 702 SP10 with GW_CORE 20. SP3
Backend: NW 702 SP10 with IW_BEP 2.0 SP3
Note 1669686 has been implemented but had no effect.
Thanks in advance.
Thanks to Han Tran at SAP Netweaver Gateway Core Team the problem is solved!
If you should encounter the same problem - check that the entry for SAP System Alias does is not marked "For local app". This checkmark should only be set if Gateway hub and backend is installed on the same system.
I have created the Data Model & Consumption model in Dev. 200 and trying to 'Validate Service' through Tcode '/IWFND/MAINT_SERVICE'.
I am facing the issue as 'Z_BANK_0001_PS' '01' '' does not exist.
My GW system is Dev. 200 and Bankend system Dev. 220, which is cross-client.
I have not created any any classes or coding in my backend system
Any suggestions please...
I have followed almost all the step mentioned above, but I am facing the same issue. I tried both way, marked Alias as "For local app" as well as unmarked it.
My back end system and net weaver system are same. Still, same issue is coming to me. Please help.
