Gwari,
thanks for the feedback.
What I did was create a new destination (SAP_SRM_1) and restart the server. Everything was ok. Now I can create the UWL "Webflowconnector".
But I can not map the portal roles with the back end.
I try to access: System Administration> System Landscape> Roles Available from Packages> select the role and click the Connect to Back End button an error is generated (Connect to Back End.png). Only the roles for SAP SRM.
An event occurred: accessing a scroll appeared options "Portal System" as shown in the image. I realized the selection of an option that is not on this list more. From this the system alias (SAP_SRM) was signed for this "portal system" selected and could not withdraw more signature is to be able to map to the correct back end. After that I did the deletion of system and created this SAP_SRM_1.
What I need is to rehabilitate the mapping of roles and can restore the system alias SAP_SRM.
Thank you for the support.
