Minimum authorization for user to execute workflows

[Reyes Diaz, Damian]

Hi,

I have to assign roles to one user in order to execute a workflow. In fact, this user will execute SAP_WAPI_START_WORKFLOW rfc.

Following sap documentation, I must assign SAP_BC_SRV_USER role to all user who can start workflows.

But I get the following error: User XXXX has no authorization to start workflows.

Which role must have one user to be able to start a workflow. User are possible agents of workflow.

Thanks in advance
