About uwl_service user and Delta Pull Mechanism

[Former Member]

Hi Experts,

We want to enable Delta pull mechanism as the help says:  http://help.sap.com/saphelp_nw70/helpdata/en/eb/101fa0a53244deb955f6f91929e400/frameset.htm

The help says there is a default uwl_service user in portal, and will generate a uwl_service in abap side.  But our scenario is our portal use abap as ume datasource. So there would be to uwl_service user in UME, would that be a problem? As  concerning of this problem, I have deleted the uwl_service user in portal, The system is reporting a warning in log-viewer. And the Delta Pull Mechanism is not working, any suggestions?

Regards!

It shouldn't cause any problem if you have two "uwl_service" users within the UME. The important thing is that the user which you use to create the RFC destination for the UWL connector also exist at the corresponding backend system (through the same UME, or through user-mapping).

You also must ensure to assign the SAP_BC_UWL_SERVICE to the user which you'll use to create the connector within UWL.

Following is an interesting page to be checked in case you have any problems during the creation of the connector when you inform the Delta Pull settings:

Let us know if you still have problems.

Hi ,

As mentioned earlier there is no issues in that. Please follow the below steps..

• Define the SAP ECC system and Alias (SAP_ECC_HumanResources)
• Define the UWL WebDynpro Launch System and Alias (SAP_LocalSystem)
• Configure the UWL Delta Pull mechanism within the ECC system and client
• Configure the UWL System Connectors for Delta Pull

Create UWL_SERVICE User in the backend as a system user.

Assign him these roles

SAP_BC_UWL_SERVICE

SAP_BC_UWL_END_USER

SAP_BC_BMT_WFM_UWL_END_USER

In Se38 create two variants one fore delta pull and full pull for program RSWNUWLSEL.

create background jobs for these to variants as per your requirment to run and run these jobs with user UWL_SERVICE

Now Configure J2EE Destinations for UWL Delta Pull

Login in NWA and go to Destination. Create these three destination

SAP_ECC_HumanResources$WebFlowConnector

SAP_ECC_HumanResources$AlertConnector

SAP_ECC_HumanResources$SomProviderConnector

While creating the above Destination to the backend use UWL_SERVICE user

Hope this helps.

Thanks

Hi Rishi,

I have created the destination SAP_ECC_HumanResources$WebFlowConnector, however, I used sapjsf as the connector user. When I use uwl_service as you suggested, the  destination got error message when ping the destination, The message is 'You have no password; you cannot log on using a password'.

Further more, when I create the background job for delta pull, which the frequency is 1 min, the job will create many spool requests, and use out the resource of spool. What is the problem I have?

Hi ,

Can you please post me the connection screen for the destination. this message doesnot looks to me correct"the  destination got error message when ping the destination".

I would suggest to create delta pull at every 15 min rather than every min.

Thanks
