In TM1 Web or in a Cube view from Architect/Perspectives, after inputing a value, a user can undo or redo his/her input.

It is great to be able to redo a change of data but on the other hand, a user clicking the redo or undo button can cause the TM1 server to hang for several minutes.

That is why many people asked if it is possible to remove the Undo and Redo functionality. Even though there is no official settings which can turn on or off this feature, a workaround exists (only for TM1Web).

The workaround consists of a manual change to the TM1 Web css file in order to remove the undo and redo icons. This workaround is however not supported by IBM. It is a hack, and therefore after any software upgrade, you will need to do this again.

This trick has been tested on a Websheet, Cube Viewer, TM1Web URL API and all working as expected. The only problem will be that it require the users to clear their browser cache if they have previously opened TM1Web before.

This workaround works with TM1 10.2.2 and Planning Analytics, however as you can see below the steps are slightly different.

In TM1 Web 10.2.2, you can find the Undo and Redo icon just after the paste icon:

To remove these icons, follow these steps:

1. Go to the following directory {tm1 directory}webappstm1webcss

2. Open the file standaloner.css as administrator

3. Look for .undoIcon and replace the following code

undoIcon {background-image: url(../images/toolbar/action_undo.gif); width: 16px; height: 16px;}

with

undoIcon {display:none;background-image: url(../images/toolbar/action_undo.gif); width: 16px; height: 16px;}

We are adding the display:none css class to hide the Undo icon. In the standaloner.css, the undoIcon appear twice. So you will have to repeat this step a second time.

4. Do the same for the .redoIcon, replace the following code:

.redoIcon {background-image: url(../images/toolbar/action_redo.gif); width: 16px; height: 16px;}

with:

.redoIcon {display:none;background-image: url(../images/toolbar/action_redo.gif); width: 16px; height: 16px;}

5. Save the standaloner.css file.
6. You don’t need to restart TM1 Web, just open TM1 Web from any browser, make sure browser cache is cleared. Now you should see that the icons disappeared:

In the TM1 Web version of Planning Analytics, you can find the Undo and Redo icon just after the paste icon:

To remove these icons, follow these steps:

1. Go to the following directory {tm1 directory}webappstm1webscriptstm1webthemesflat

2. Open the file flat.css as adminsitator

3. Look for .tm1webUndoIcon and replace the following code

.tm1webUndoIcon {background-image: url("share/toolbar/images/menu_undo.svg");}

with

.tm1webUndoIcon {display:none;background-image: url("share/toolbar/images/menu_undo.svg");}

4. Do the same for the .tm1webRedoIcon, replace the following code:

.tm1webRedoIcon {background-image: url("share/toolbar/images/menu_redo.svg");}

with

.tm1webRedoIcon {display:none;background-image: url("share/toolbar/images/menu_redo.svg");}

5. Save the standaloner.css file
6. You don’t need to restart TM1 Web, just open TM1 Web from any browser, make sure browser cache is cleared. Now you should see that the icons disappeared:

Navigate to new TM1 Web’s (or PASS’s) installation directory: ..Program Filesibmcognostm1webwebappstm1webscriptstm1webthemescarbon

1. Take a back-up of existing carbon.css file;

2. Edit the carbon.css as an administrator (you may use notepad++);

3. Conduct the find/replace changes:

Change # 1:

1. Find: .tm1webUndoIcon {background-image: url(“share/toolbar/images/tbar-undo.svg”);}

2. Replace with: .tm1webUndoIcon {display:none;background-image: url(“share/toolbar/images/tbar-undo.svg”);}

Change # 2:

1. Find: .tm1webRedoIcon {background-image: url(“share/toolbar/images/tbar-redo.svg”);}

2. Replace with: .tm1webRedoIcon {display:none;background-image: url(“share/toolbar/images/tbar-redo.svg”);}

1. Save the file;

2. Launch a new browser session for TM1 Web (ensure your browser cache is cleared), or you may launch chrome in Incognito mode to validate.

3. You should no longer see the two undo and redo icons.
