Unable to delete User Group after upgrade from AX 3.0 to AX 2009

Sometimes you are not able to delete user groups which are migrated from AX 3.0. The effect is as follow: you try to delete and the row removes, but re-opening the form will show the user group again.

This happens if the configuration key for Reporting Services is enabled, but there is no Reporting Services Server refered and configured in AX.

With a little modification in AOT/Forms/SysUserGroupInfo/Data Sources/User Group Info/delete you can workaround the problem.

public void delete()
{
    userGroupId groupID;
    SysSRSTablePermissions permissionsTable;
    AifEndpointUser aifEndpointUser;
    SysSecurityFormTable    sysSecurityFormTable;
    ;

    groupID = userGroupInfo.Id;

    ttsbegin;

    delete_from aifEndpointUser
        where aifEndpointUser.UserId == groupID
        && aifEndpointUser.AxaptaUserType == AifAxaptaUserType::UserGroup;

    delete_from sysSecurityFormTable
        where sysSecurityFormTable.UserGroupId == groupID;

    super();

    if (isConfigurationkeyEnabled(configurationKeyName2Id('ReportingServices')))
    {
        //Now that the group is deleted, we can synchronize all the secure views that
        //include RLS criteria for this group. We need to keep the record for this
        //group in SRSTablePermissions for now because they are used to determine which
        //tables have permissions assigned to them for the specified group.
        //Once all views have been synchronized, then we can delete those records.

        if (SRSSecureViewManagerProxy::syncWithGroup(groupID) != 0)
        {
            // modificaton begin
            if ((select * from SRSServers).RecId)
            {
                ttsabort;
                return;
            }
            /*else
            {
                just fall trough, there is no need to abort, since there is no Reporting Services Servers located
            }*/
            // modification end
        }

        //Delete all records for the group from the SRSTablePermissions table.
        delete_from permissionsTable where permissionsTable.GroupId == groupID;
    }

    ttscommit;
}

Now your able to delete migrated user groups.
