Hi

Description

I_SELECTION = 'X' => the user can select entries in the displayed

internal table.

Default

Entries selectable

Description

The structure SELFIELD contains the following information about the

current cursor position

o tabname : internal output table name

o tabindex : internal output table index

o fieldname: field name

o value : field contents

Multiple selection using checkboxes puts an 'X' in the

I_CHECKBOX_FIELDNAME field in the corresponding row in the internal

table.

E_EXIT

Description

Flag is set when the user leaves the popup with the 'Cancel' function.

I_SELECTION

If 'X' user can select a record, if space the Function Module only display the list, no selection possible.

E_EXIT

If 'X' user has canceled the selection (clicking back/cancel pushbutton)

E_SELFIELD

In case of single selection, this parameter returns information on cursor position of selected item : table, index, field name and value.

Hello Udaya Kumar,

ISELECTION_ is used for selecting the internal table contents displayed in ALV.

If I_SELECTION is not Checked, it only to display the internal table contents.

If I_SELECTION is Checked (X) Selection of internal table contents displayed is possible.

ESSELFIELD_ using this, the information about the field in which cursor position is will display the information like TABLE NAME, TABLE INDEXM, FIELDNAME and VALUE.

tabname : internal output table name

tabindex : internal output table index

fieldname: field name

value : field contents

Multiple selection using checkboxes puts an 'X' in the I_CHECKBOX_FIELDNAME field in the corresponding row in the internal table.

EEXIT_ is used to cancel by the user.

If it is checked 'X', the user leaves the popup with the cancel function.

Reward If Helpful.

Regards

Hai,

without those import and export paremeter also i can select values and i can display the selected values, then why i should use those variable, any one can say exact answer for that question

[RaymondGiuseppi]

Import parameter

This import parameter has a default value 'X', if you don't use it , it will take this value (look at definition of function module)

Export parameters

Those parameters are available, if you don't need them don't use them. They give you information that's all. You can also use the I_CHECKBOX_FIELDNAME parameter and then loop at the internal table after the call (Especially if multiple selection is required)

The choice of parameters to use depends on the definition of the function module AND of your needs, there is no definitive answer.
