Hi,

what is the use of AT LINE-SELECTION

where we use this what is the use of GET CURSOR FIELD.

Hello,

AT LINE SELECTION is basically used when you are displaying in the Interactive reports. This is used once the BASIC list is generated.

GET CURSOR FIELD is used to capture the cursor field in the output list and it is stored in the Field value " FVAL ".

Sample Program :

Just copy n paste this program and execute, you will come to know

REPORT z_find_userexit NO STANDARD PAGE HEADING.

hi

<b>AT LINE-SELECTION.</b>

When the user triggers the function code PICK, AT LINE-SELECTION is always triggered if the cursor is positioned on a list line. The function code PICK is, by default, always linked with function key F2 and hence with the mouse double-click. Consequently, if you have a simple program that does not react to any further user actions, you only need to write this event block.

AT LINE-SELECTION.

<statements>.

As described in the section Dialog Status for Lists, the function code PICK is always added to the standard list status when you have an AT LINE-SELECTION event in your program.

If you assign PICK to other function keys or menu entries, AT LINE-SELECTION is also triggered when the user chooses then. You should avoid this for the sake of the semantics.

Conversely, if you have a more extensive program that does not react to line selection, you should not use the function code PICK. Instead you should assign a different function code to F2 , to ensure that as many events as possible trigger the AT USER-COMMAND event.

<b>GET CURSOR FIELD field</b>

[OFFSET offset]

[LINE line]

[VALUE value]

[LENGTH length]

[AREA area].

You use this command to return the name of the field on which the cursor currently stands. The additions also give information about the cursor’s offset within the field, the number of any step loop line or absolute list line present, the current value, the field’s output length or the name of a control, if present. You can use this command both in dialog processing and in interactive reporting.

go to this link, it will be helpful.

Hi,

<b>AT LINE-SELECTION</b> : This Event triggers when we double click a line on the list, when the event is triggered a new sublist is going to be generated. Under this event what ever the statements that are been return will be displayed on newly generated sublist.

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>].

Hi Kalyani,

In the report, if the user double clicks on a word or clicks on a hot spot, and you want to perform some operation based this input. in this case you go for AT line selection event.

get cursor field will return the field name and the value which the user has clicked.

see the sample program below

-

---

report ztest.

data: f(20) type c,

v(20) type c.

&----

---

*& START-OF-SELECTION *

&----

start-of-selection.

write: /, at 50 'Yahoo' hotspot on.

skip.

write: /, at 50 'Google' hotspot on.

skip.

write: /, at 50 'Yahoomail' hotspot on.

&----

---

*& AT LINE-SELECTION *

&----

---

at line-selection.

get cursor field f value v.

case v.

when 'Yahoo'.

write: 'You have pressed Yahoo'.

when 'Google'.

write: 'You have pressed google'.

when 'Yahoomail'.

write: 'You have pressed Yahoo Mail'.

endcase.

Hi,

AT LINE-SELECTION is generally used when u go for interactive report and u want to insert detailed list within the basic list.

GET CURSOR FIELD is used to get the position of cursor at a particular point in the program.

For any further help u can get the syntax and more detailed description on help,sap.com

Pls reward points if useful.

at line selection is used in interactive reports to move from one list to another.

get cursor field returns the name of the field upon which the cursor is placed.

Hi,

GET CURSOR FIELD and GET CURSOR LINE commnad is used to to pass the output field or output line on which the cursor was positioned during the interactive event to the processing block.

Syntax

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

[VALUE <val>] [LENGTH <len>].

AT LINE-SELECTION

Moment at which the user selects a line by double-clicking on it or by positioning the cursor on it and pressing F2.

Thanks,
