Hi Experts,

I'm a beginner of SUP MBO and Workflow Development in SUP 2.1.3.

It's possible to call SAP BAPI by SUP with fixed username and password

which are same as the development time.

in this case transaction was done by the same user in SAP at any time.

but I want to do is to propagate username and password which are enterd in workflow screen to SUP

and to be done for each transaction by each SAP account.

The following is a procedure was developed and deployed In brief.


1, create MBO, and set the data source definition page, in the Runtime Data Source Credential section for BAPI and Workflow.

2, create screens with Client-initiated and Credential Request.

3, set menu item in screen of Credential Request, which has type submit workflow.

4, deploy MBO and Workflow.

The referenced document is

Propagating a Client's Credentials to the Back-end Data Source in Developer Guide: Mobile WorkflowPackages”.

I appreciate your help.

Best Regards

Misleading because there was some content to the contents of the last, we will append.

I set the username and password pre-defined in the runtime data source of MBO,

and specifies input field of username and password with credential cache  at the Credential screen.

Then, the motion will occur in two ways.

1,  it is an error in the SAP, when I use the 'supAdmin' to propagate as username.

2,  it is an error in the SUP, when I use a non supAdmin as username.

Currently, authentication is running in the (SAP and SUP) in two places,

I think one authentication and  want to SAP.

To run without the same SAP user and the user SUP,

I use SAP users only, and want to achieve the authentication process.

What should I do now?

I appriciate your help.

Best Regards.
