Unable to save Lumira Discovery Document

Hi,

I am using BO 4.2 SP4.One of my user is unable to save a Lumira Discovery Document .He is trying to create a Lumira Discovery document from Bi launchpad.

Can anyone please help me in knowing which security should i assign to the group so that all the users of that group will be able to save the "Lumira Discovery" document.

Please help.Thanks in advance.

NOTE: Any admin user is able to save the Lumira Discovery document.I checked the assigned security to the Admin group and the normal group and it looks same.
