How to Merge backend role and work as click in sap portal?

Hi Experts,

I have uploaded two backend ECC role in portal Say "A" and
"B". A contains Tcode A1,A2 and B contains tcode B1,B2. Based on this
I have below questions:

1. As the portal setup I can find the tcode description in portal but when I
click them its not evoking the transaction instead I have to input them just
like GUI. As you can see in below Image Role(Approve/Create purchase order)
have 4 tcode assigned and it is visible through tcode description but when I
click them it still shows user menu instead running the tcode.

How to setup so by clicking on tcode description it will run the tcode?

2. I want to combine Role A and Bunder one tab says ECC how to make it happen?

Appreciate your quick response on this.

Thanks,
