How to remove the Workplan tab?

  Hi Everyone,

 

I am not too familiar with the HTML responsibilities and need to remove the Workplan tab from the Project Manager responsibility (a variant of the Project Super User responsibility). Tried removing it from the sub-menu ‘Project Workbench Tab Structure’. But, apparently, that has not done it.

 

Can someone suggest how I can remove the Workplan tab?

 

Thanks
