hi lavanya,

did u write the "call subscreen.......sub............" statement PAI side also..

while performing insert you have to call the subscreen at the PAI side with the above statement

This statement should be in mainscreen ie screen number 100 only.

Regards,

this values are stored in a internal table...U can use the internal table and insert the values into the database.

Hi,

Check this,

TABLE CONTROL are the screen elements used to display tabular data they can be called as screen tables( like STEP LOOP).To use table control we have to create it on the screen using SCREEN PAINTER(SE51) and declare a control variable of TYPE TABLEVIEW using CONTROLS statement in the ABAP program. We have to use LOOP .. ENDLOOP statement in both PBO and PAI with or without AT int_table parameter. IF AT int_table parameter is not used than we have to place a MODULE call between the LOOP...ENDLOOP statement to fill the screen table rows from the ABAP program in PBO and program our own scrolling functions using OK_CODE field.

Having a parallel loop(at screen table rows & int table rows) by using parameter

AT int_table makes the ABAP code simple. A special structure of type XTAB_CONTROL is used to set/get various attributes of table control at runtime like CURRENT_LINE ,TOP_LINE.

ABAP declaration

CONTROLS: tab_con TYPE TABLEVIEW USING SCREEN nnnn

Here tab_con is the same name we used in screen for the table control. This ABAP statement will declare a control variable that will be used to access the table control , and set it's various attributes like number of fixed columns(tab_con-FIXED_COLS) ,total number of records it will display(tab_con-LINES).It is of type CXTAB_CONTROL and is a deep structure(structure containing structures).

REFRESH CONTROL tab_con FROM SCREEN nnnn

This ABAP statement will initialize the table control on the screen nnnn to its initial values.

PBO processing

In PBO we have to use the screen LOOP ...ENDLOOP statement , with or without

intenal table.

LOOP WITH CONTROL tab_con.

MODULE fill_tab_con.

ENDLOOP.

Here a module should be called between the loop endloop statement to transfer data from th ABAP program to the screen table through a structure.This module should use the CURRENT_LINE attribute of the table control variable to get the current screen table record index to read the data from the internal table into a work area.

e.g.

READ TABLE int_table INDEX tab_con-CURRENT_LINE

The record read will be placed in the header line of the internal table and will be available to the similarly named screen fields or if these are different it can be written explicitly. e.g.

screen_field_name = int_table-field_name

...

.

LOOP AT int_table INTO workarea WITH CONTROL tab_con CURSOR i FROM

n1 TO n2.

ENDLOOP.

Here the module call is not required to fill the screen table.The CURSOR parameter is a integer of type I indicating which absolute internal table line should be the first to display on the table control .FROM n1 TO n2 can be used to restrict the starting line and ending line number of the internal table , they are of type SY-TABIX.

In both cases before the LOOP statement a module should be called which is generally for setting of status ,in which we should fill the LINES attribute (tab_con-LINES ) of the control with the total number of internal table records,doing this ensures correct and automatic scrolling. The ABAP statement DESCRIBE TABLE int_table LINES lines can be used to get the total lines in an int table.

PAI Processing

We have to use LOOP ... ENDLOOP in PAI so that data can transfer fro table control to ABAP program. If we want to write changes to the data we should call a module between the LOOP ... ENDLOOP. The MODULE call to process user commands (SY-UCOM) should be called after the ENDLOOP statement.

e.g.

PROCESS AFTER INPUT

MODULE mod AT EXIT-COMMAND.

LOOP AT itab_table or LOOP "depending on whether we are using AT int_table

MODULE modify_int_table.

ENDLOOP.

MODULE user_command.

In the MODULE call modify_int_table we can use

MODIFY int_table FROM workarea INDEX tab_con-CURRENT_LINE

or we can use

int_table-field_name = screen_field_name.

Hope this helps.

Feel free to revert back.
