ranges date type... how it works
Here is my question:
How does ranges types work.
I came across this code:
ranges: hrs for t512t-lgart
ls_range LIKE t512t-lgart,
*Fill constant values in range
ls_range-sign = 'I'.
ls_range-option = 'EQ'.
*Load range tables with preliminary values
move-corresponding ls_range to hrs.
I dont got this..Can you explain how sign and option works..what is the purpose behind it
