Users run a BEX report, key in a month in the variable screen and execute and using this month we need to fetch list of
sales orders from a DSO and then pass them to Sales orders variable. Until this I can
do it using i_step = 2 using month as ref variable. After this, can we show the selection
screen again with list of sales orders fetched from DSO in the sales orders variable? Are we supposed to use i_step = 3?
