SAP Portal 7.3 missing components

Hi Guys,

We installed sap portal 7.3 with only EP CORE Usage types and we went live recently.

But we are tying to install missing .sca files, which are

EP APPLICATION EXTENSTIONS 7.31

KMC BASE COMPONENTS 7.31

KMC COLLOBARATION 7.31

KMC CONTENT MANAGEMENT 7.31

EPWEBPAGE COMPOSER 7.31

via SUM Tool, but we are getting errors :Component sap.com/EP-APPS-EXT is part of the following usage type EPC.

Please help me to understand how can we install these missing components, now SDM and JSPM both are deprecated in 7.3, and only way to install is using SUM Tool and it doenst work..

Please see the attached error screen shot from SUM tool.

Any answers are appreciated.

Thanks,

Vinay
