What is the difference between <b>Get Cursor</b> & <b>Hide</b> use in the interactive reports?

Please send me the answer. Thanks.

hi,

<b>GET CURSOR</b>

<b>Use the statements GET CURSOR FIELD and GET CURSOR LINE to pass the output field or output line on which the cursor was positioned during the interactive event to the ABAP program</b>

After user interaction with the screen, you may need to know the position of the cursor when the action occurred. This is particularly important if the user chooses the Choose function (F2 or mouse double-click).

To find out the cursor position, use the following statement:

GET CURSOR FIELD <f> [OFFSET <off>]

[LINE <lin>]

[VALUE <val>]

[LENGTH <len>].

<b>HIDE</b>

<b>You use the HIDE technique while creating a list level to store line-specific information for later use</b>. To do so, use the HIDE statement as follows:

<b>HIDE <f>.</b>

This statement places the contents of the variable <f> for the current output line (system field SY-LINNO) into the HIDE area. The variable <f> must not necessarily appear on the current line.

To make your program more readable, always place the HIDE statement directly after the output statement for the variable <f> or after the last output statement for the current line.

GET CURSOR statement transfers the name of the screen element on which the cursor is positioned during a user action into the variable <f>.

GET CURSOR FIELD <f> [OFFSET <off>] [LINE <lin>] [VALUE <val>] LENGTH <len>].

To prevent the user from selecting invalid lines, ABAP/4 offers several possibilities. At the end of the processing block END-OF-SELECTION, delete the contents of one or more fields you previously stored for valid lines using the HIDE statement. At the event AT LINE-SELECTION, check whether the work area is initial or whether the HIDE statement stored field contents there. After processing the secondary list, clear the work area again. This prevents the user from trying to create further secondary lists from the secondary list displayed.

See the example programs :

Hello Chandan,

Explain in simple terms :

Hide : it hides the complete line ,when you double click on line ( anywhere in the line ) ,it will trigger and shows secondary list.

some times Customer requirement is he want to have on field ( not like complete line),then we go for cursor field ( it hides only certain fields - here we use hot spot on that field)

Hope you got it.

Thanks

Seshu
