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
