What are the difference between these two SWO1 methods ?

Can anybody tell me what is the difference b/w methods in SWO1 with a green indicator and with green indicator missing . An screenshot is attached below . There are two methods in the highlighted box .One has a green indicator and the other one does not have so .What is the difference between these two .

And one thing that i have noticed is that the ones with grren indicator will be shown in BAPI explorer (I mean the Tcode BAPI)
