Table Control

Former Member — Mon, 06 Aug 2007 10:16:39 GMT

Hi,

I have a table control in a screen with three input enable fields. And also a button "Post". I want, if user press the button without entering any record in table control, then there will be a error message.I am able to display the error message but the table control is becoming disable. I want after pressing enter again table control will be again input enable.

How could I solve this.

Regards,

Saroj.

Clear the variable holding the OK Code of the clicked button before showing the error message.

Please mark points if the solution was useful.

Hi,

Make sure you are rasing the error message from a PAI module which is executed on these three fields like this.

in the flowlogic

LOOP AT itab.

CHAIN.

FILED1.

FIELD2.

FIELD3.

MODULE check_input ON CHAIN-INPUT.

ENDCHAIN.

ENDLOOP.

Raise your error messagr from the PAI module check_input.

hi ,

Have you looped at the table control global internal table in the PBO of the screen flow logic ? Please check there . I think that is the area where the bug lies .

Hi,

If user does not enter any record in table control, then itab will be blank and then control never goes to the line module check_input.

please reply.

Thanks,

I have looped at at the table control global internal table but If user does not enter any record in table control, then internal table will be blank and control will jump to the endloop statement.

please reply.

I am not sure where you are facing problem ..

May be here you can refer to these 2 sample programs and get some idea from there about programming using table control .

To get an overview about table control check these programs in SE38

DEMO_DYNPRO_TABLE_CONTROL_1

DEMO_DYNPRO_TABLE_CONTROL_2

Even in Txn SAPDOCU you can get few more programs for table controls .

Else post your code here so that we can help you out .

Hi,

PROCESS BEFORE OUTPUT.

MODULE status_0100.

LOOP AT t_itab2 WITH CONTROL tbc1 CURSOR tbc1-current_line..

MODULE fill_table_control.

ENDLOOP.

PROCESS AFTER INPUT.

LOOP AT t_itab2.

CHAIN.

FIELD eban-matnr.

MODULE check_data4 ON chain-request.

ENDCHAIN.

ENDLOOP.

MODULE user_command_0100.

MODULE back_0100 AT EXIT-COMMAND.

PROCESS ON VALUE-REQUEST.

FIELD t_itab1-battery MODULE f4_battery.

This is my code. My table control fields are input enable.If user does not enter any value in table control then it should give an error message. But the problem is control is entering into the loop because t_itab2 is blank.And it also not executing the MODULE check_data4 ON chain-request.

Thanks,

Saroj.

if u want to check when No values are there...then u should not give inside the loop.

PAI...

Chain.

field l_field1.

Module validate_fields.

endchain.

In this module check

if values are not there ie initial....then give error message.

Then have ur rest of the codes..

LOOP AT t_itab2.

CHAIN.

FIELD eban-matnr.

MODULE check_data4 ON chain-request.

ENDCHAIN.

ENDLOOP.

MODULE user_command_0100.

MODULE back_0100 AT EXIT-COMMAND.

PROCESS ON VALUE-REQUEST.

FIELD t_itab1-battery MODULE f4_battery.

In PAI,

Check whether the t_itab2 is initial i.e. the global table is initial or not , if it is not initial then loop it and write the rest of the logic and if it is initial then give the error message .

Revert if further assistance needed .

If I will give the error at checking the internal table then all the input enable fields will be disable. Then user can not do anything.

you can not use field statement outside the loop incase of table control.

Hi,

Try this way,

In <b>MODULE user_command_0100.</b> or

<b>MODULE back_0100 AT EXIT-COMMAND.</b>

IF "POST" was pressed...


IF <table name[]> IS INITIAL.
  MESSAGE ID id TYPE mtype NUMBER n.
*  EXIT. If necessary
ENDIF.
