HTTP handler for starting an external service cannot be read

Former Member — Wed, 18 May 2005 11:44:25 GMT

Hi,

When i execute the work item from Business Work place and also from the UWL in Enterprise portal of the task TS21300098 for HR Process Requisition workflow.

In the Error is says

HTTP handler for starting an external service cannot be read

Message no. SWK045

Diagnosis

This work item is a link to a HTTP service. To start the service, a launch handler must be known to the SAP System.

However, the system could not find a launch handler.

System Response

The workflow system cannot start execution of the work item.

Procedure

Contact your workflow administrator:

In Customizing you must maintain a launch handler for HTTP-supported dialog services.

I have checked the config under WF_HANDCUST transaction and made the launch Handler settings generated automatically.

But still the problem occurs.

Any Suggesions and help?

Thanks & Regards

Sumanth

In SICF transaction check whether the service "<b>sap/bc/workflow_slh</b>" is active or not.

This could be one of the reasons.

Hi,

Is it possible for you to generate URL and test the handler in trx. WF_HANDCUST without first have to logon in a browser?

hi Guys,

I have got the same issue. This blog helped me with tcode WF_HANDCUST. I have generated the url

http://waspgh.kcc.com:8083/sap/bc/webflow/wshandler-->Click on Generate URL and click on distribution.

Immediately u will get click on Test url . Click Test url . Then It is not successful. It stopped at

http://waspgh.kcc.com:8083/sap/bc/webflow

Getting http page error. So use tcode sicf ~~>sap~~>bc-->webflow service and activate it.

Then test the connection. It will be successfull.

Handler test

Test successful

Thanks,
