explain the HIDE technique
in report programing and its use
<b>The HIDE Technique</b>
You use the HIDE technique while creating a list level to store line-specific information for later use.
This statement stores the contents of variable <f> in relation to the current output line (system field SY-LINNO) internally in the so-called HIDE area. The variable <f> need not necessarily appear on the current line.
As soon as the user selects a line for which you stored HIDE fields, the system fills the variables in the program with the values stored.
