Archive Button Label

Hi Experts!

I need to change the label of the Archive Button (of the approval process). The reason for this is that this command cannot be removed and i need the users not to use it.

Reading some documents, i've found that i should change the value of the label xbut_Archive in the file UIConsts.properties in the file

\WEB-INF\portal\portalapps\com.sap.km.cm.ui.flex\lib\km.shared.ui.flex.uicommand_api.jar

I did it, but it didn't work.

Please, this is very urgent. I will reward points!!!

Thanks in advance,

Fede
