Hi Lavanya,

The problem is when i give the function code and click it goes PAI and PBO but i can get the values from the list box.

Hi,

The selected value from the list box will be updated in the internal table which is attached to the table control. Just check the internal table contents for that row. The selected value should be there.

hi,

PROCESS AFTER INPUT.

MODULE user_command_0100.

loop at it_time.

module get_data.

endloop.

PROCESS ON VALUE-REQUEST.

FIELD X_TIME-CUSTOMER MODULE CUSTOMER_details.

here my X_TIME-CUSTOMER is the table control field name

it_time is my internal table. the problem is when i select values in

X_TIME-CUSTOMER listbox and try to retrive in PAI the value is null .

[sivasatyaprasad_yerra]

Hi,

Are you updating the internal table based on the value selected by the user in MODULE CUSTOMER_details. If you don't update the internal table, values will be lost. So, just check this and attach the code of MODULE CUSTOMER_details if it doesn't solve the problem.

HI Siva,

I am not updating the internal table once value is selected from the list box the problem is i am not able to retrive the values from the screen field X_TIME-CUSTOMER

I have pasted the code for the POV...please help

module CUSTOMER_details input.

data : v_cus_count TYPE i,

v_pspnr TYPE i,

v_project(8).

*-----Check already listbox has data.

if l_clist is INITIAL.

l_cname = 'X_TIME-CUSTOMER'.

SELECT cust_no FROM zassignment

into (zassignment-cust_no)

where EMPLOYEE_ID = LFA1-LIFNR

ORDER BY cust_no.

+v_cus_count = v_cus_count + 1.+

l_Cvalue-key = v_cus_count.

l_Cvalue-text = zassignment-cust_no.

APPEND l_Cvalue to l_clist.

ENDSELECT.

CLEAR v_cus_count.

*-----Upload the data to the list box.

CALL FUNCTION 'VRM_SET_VALUES'

EXPORTING

id = l_cname

values = l_clist.

endif.

endmodule. " CUSTOMER_details INPUT

[sivasatyaprasad_yerra]

Hi,

If i'm not wrong:

l_clist contains the values to be displayed in the list box. So, if the list box contains the values then your code will not have any effect because entire code is in if block. Please check whether this is correct or not?

Check all these thing by debugging the POV module.

The structure you have used is X_TIME to display the internal table. So, when you select any value this structure will be updated and this value you have to modify in the internal table it_time

with the current line no of the internal table.

I don't have code snippet to explain this behaviour.

Siva.

Hi Siva,

The problem is the system is not passing the values for the structure XTIME-Customer alone but i have a other field XTIME-PROJECT which is a ordinary text box in my table control where i am able to to read in PAI loop and Endloop.

Is that any steps to be followed while changing textbox to list box .If so please explain?

Regards,

Karthik

[sivasatyaprasad_yerra]

Hi,

I've tried this. I was able to read the selected list box value. When i update the internal table with the new value, UI displays selected value. Just modify the internal table in the PAI loop..endloop for the current line of table control.

NOTE: List box values are coming from data element.

Regards,

Siva.

Hi Siva,

Can you please paste the code ...so that i can get an clear idea

Karthik.

[sivasatyaprasad_yerra]

Hi,

PROCESS AFTER INPUT.

MODULE USER_COMMAND_1000.

loop at lt_table_temp.

module table_1000_input.

endloop.

-

---

MODULE TABLE_1000_INPUT INPUT.

wa_table_temp = zdemo_ts_sub_device_dmswcv-operator.

read table lt_table_temp transporting no fields index table_ctrl-current_line.

if sy-subrc = 0.

modify lt_table_temp from wa_table_temp index table_ctrl-current_line.

else.

append wa_table_temp to lt_table_temp .

endif.

ENDMODULE. " TABLE_1000_INPUT INPUT

zdemo_ts_sub_device_dmswcv is the structure which i'm using.

lt_table_temp is the internal table which is used for table control.

table_ctrl is the Table control name

I don't have POV module.

Reward points if it is useful

Hi Siva,

Thanks for your extended help.But still i have a clarrification,which is zdemo_ts_sub_device_dmswcv-operator did you assign this field as get from program or get from Dictionary .Because in my case i got it from Program.If the other case how to create a zstructure for my userdefined table..

Regards,

Karthik.

[sivasatyaprasad_yerra]

Hi,

I've used that field by "Get from Dictionary" option. You can create structure for your table as follows:

Create a structure with some name.

enter the field values as

component = .include

Type category = Type

component type = * your table name*.

You can use this strcuture in your screen.

Reward points if useful.

Hi Ganesh,

Place a Textbox in the table control and change the DROPDOWN option as Listbox.

[Former Member]

Thank all.....Problem solved it was the function module in the POV that was troubling me... instead of VRM_SET_VALUES i now used F4IF_INT_TABLE_VALUE_REQUEST that was working fine...

Thanks all specially SIVA....you helped me lot in fixing it.
