Active version needed for layout set

Dear Experts,

I am going to create a certificate profile but in the process system is giving me this message while I click on the tabs (materials, characteristics) and also before release the profile.

An active version of layout set ZQM_MCIL_CHEMICA is not yet available

Message no. QC034

Diagnosis

An active version of layout set ZQM_MCIL_CHEMICA is not available in the system.

Procedure

Check your input.  It could be for one of the following reasons:

• The layout set does not exist and must first be created.
• The layout set is new but not active. Activate the layout set.

Now I want to know how could I active It.

Thanks.
