How to lock a record when updating a page

(0) ShareShare

Posted on by mbr 5,136

Is there any way I can lock a record as I get into Card Page?  This way, any changes I make will supercede any changes made by other users, assuming I was the first one to open the page.  Also, how can I error out if the record I am trying to modify was opened first by another user?

    1. Create a new field "LockerID" in your table

    2. Put

       LockerID := USERID;

       Modify;

    In OnOpenPage trigger

    3.  Put

       LockerID := '';

       Modify;

    in OnClosePage trigger

    4. Put

    if LockerID <> USERID then

      TESTFIELD(LockerID, '');

    in OnModify trigger in your table

    Seems to be a nice approach as mentioned by above just in the last one

    if LockerID <> USERID then

     TESTFIELD(LockerID, '');

    I will put some realistic custom Error instead of the error that will be self generated by TESTFIELD Command.

    Yes, testfield exception is totally not user-friendly. Error is better.

    But with using error it should be like this:

    If (LockerID <> USERID) AND (LockerID <> '') then

    ERROR('Record is locked');

    In 2017 and 2018 NAV you also could create some magic:

    if LockerID <> USERID then begin

     LockNotification.MESSAGE('Record is locked');

     LockNotification.SCOPE:=NOTIFICATION::LocalScope;

     LockNotification.SEND;

    end;

    Where LockNotification is variable with type = notification

    Notifications are most user-friendly way to inform.

    Still thinking why you are adding this with AND Operator

    If (LockerID <> USERID) AND (LockerID <> '') then

    LockerID will never be blank because you already wrote this code on OnOpen Page trigger

    2. Put

      LockerID := USERID;

      Modify;

    In OnOpenPage trigger
