HIDE

The HIDE statement is one of the fundamental statements for interactive reporting. You use the HIDE technique when creating a basic list. It defines the information that can be passed to subsequent detail lists.

GET CURSOR

Use the statements GET CURSOR FIELD und 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.

A Sample Hide & Get Cursor in Interactive Programming

Hide & Get Cursor is used in interactive programming ( in the event AT LINE-selection).

Using Hide in Loop..Endloop, you can get the field name At Line-Select

Event While Double Clicking That Line.

Hi

Hide

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.

GetCursor

If the hidden information is not sufficient to uniquely identify the selected line, the command GET CURSOR is used. The GET CURSOR command returns the name of the field at the cursor position in a field specified after the addition field, and the value of the selected field in a field specified after value.

Hi Avi,

HIDE wa-field1 wa-field2. :

This statement gives the Values of the Fields for the selected line.

It will not give the Attributes like Name of the field.

GET Cursor Field v_name Value v_value.

This statement gives the Attributes of the FIELD on which the cursor is positioned

It will give the attributes like Name , Value , Length of the field.

We can als use HIDE technique while creating LIST level to store line -specific information for later use.

syntax: HIDE <variable>.

this statement place the contents of the variable <variable> for the current output line(SY-LINNO) into the HIDE area.

you can think of the HIDE area as a table, in which the system stores the field name, field contents and line number in which field exisisting. as soon as they are needed the system reads the values from the table(HIDE) using READ LINE statement.

Keep in mind while working with HIDE.

1) Allways keep HIDE <variable> statement after WRITE statement for more readable format.

2) All way keep HIDE <variable> statement inside the LOOP statement, because syatem stores all the hide variable in system genarated table space, we can process table data throug it's work area only.

Reward if helpful.
