2 . How do you validate the selection criteria of a report? And how do you display initial values in a selection screen?
3 Name a few system global variables you can use in ABAP programs?
4 What are interface/conversion programs in SAP?
5 What are the techniques involved in using SAP supplied programs? Do you prefer to write your own programs to load master data? Why?

1) ranges are similar to select-option they are mainly used to generate internal table of similar to select-option
eg: data itab type ranges of matnr.
2) u validate selection criteria in at-selection-screen event
u can initialize variables using default option or in initialization event ; in initialization event values assigned are dynamic.
3) sy-datum , sy-timlo, etc
look at table syst for system variables
5) normally SAP provided program should be used for loading the data.
Own program used only when u have customization is involved
Transaction EMIGALL is used for the Imgration of data
