How can I cancel/re-execute configuration task on NWA 7.3 which has "Currently executing" status?

 This may happen if your web session has expired during execution of configuration task which was not able to finish in the background because it needed some user input/response. The next time you login to Configuration Wizard if the server is not restarted you will see this task with "Currently executing" status which prevents you from re-executing the task. The status can be cleared by restarting the "tc~lm~ctc~cul~startup_app" application. To do this go to
http://:/nwa -> Operation Management -> Systems -> Start & Stop -> Java EE Applications
Then stop and start the application.

Approve/Confirm downloads on Maintenance Optimizer

Recently, due to a misconfiguration, our Maintenance Optimizer was giving errors blocking us from performing the download and approve of software packages through Solution Manager.

Meanwhile, while digging the web,i've found a workaround to perform a mass authorization on maintenace optimizer.
Enter TCode SE37
Enter function module:
/TMWFLOW/MO_UI_BASKET_AUTHORIZ

Execute with I_OSS_RFC = SAPOSS
Note: SAPOSS must be configured in SM59 to connect to SAP Msg Server

Also your S-User must be mapped to the user currently executing the function module. In order to map it, you should use transaction AISUSER or go through SPRO->SAP Solution Manager Implementation Guide->SAP Solution Manager->SAP Partner->Software Partner->Maintain Table AISUSER

You can check the standard and correct procedure in this link:
