This unwanted logoff could happen when you try to display or edit document info records in EasyDMS. The problem is that the logon screen appears suddenly again and the user does not get any warning or explanation for this behavior. However it might be that not all users face this issue.
By debugging the behavior in EasyDMS I found out that the reason for this behavior is located in the following coding
This function module is for example called in the EasyDMS related function module 'EASYDMS_DOCUMENT_GETDETAIL2' at
The error is essentially happening because of the introduction of a SAP Security note 1597391 in the function module: SCDC_REMOTE_CONVEXIT. Please note that this is a RFC enabled function module and hence this will be called by various RFC applications (including Easy DMS). As this function module ise used in several interfaces this kind of change cannot be removed anymore.
To verify the failing authorization check as the reason for the issue in EasyDMS you can use the authorization trace in transaction ST01 as explained at Authorization Trace in transaction ST01. In the result you should then see the failed check on object S_TABU_RFC as shown in the below screenhot.
To avoid this issue in EasyDMS the only solution is to add the necessary S_TABU_RFC permission to your users because otherwise this authorization check will fail and the user got logged off from EasyDMS.
