COnfigured using tx code SMSY - Product System is SAP ERP and product version is SAP ERP 2004.

Created logical components and assigned to <SID> of R/3 4.7 Development system.

Then created solution and configured solution landscape . Logical component was assigned to solution landscape.

Then clicked on "Create new Optimizer transaction"

Then select product version : ERP 2004

Then select Product system and selected <SID>.

But only "maintenance" button was displayed.

However "Upgrade with enhancement package" button is not showing.

Please help us the solution.
