Downloading Afaria Custom Client

Hi Team,

As per highlighted in the attached screen shot for registering Afaria custom client at the Frontline website, for Afaria SP4 there are 2 options to choose from

1. Afaria Enterprise App with SAP Portal (all systems including SP4)
2. Afaria Enterprise App (all systems including SP4)

I'll appreciate if somebody can advice the difference between the Afaria client downloaded using the 2 options.

Thanks, Vivek
