Issue during creation of control cycle

Dear Gurus,

During creation of control cycle (LPK1), the fields for source information is not appearing in my system.

I compared control cycle in a different ECC system where source information is appearing.

How can make the screen appear in my ECC system.

Please find the screenshot.

Any pointers will be highly appreciated.
