Display data in screen field F4 module pool- pasing values frm internal tbl

[Former Member]

Hi,

I have an internal table with some values.

I have to display data in a screen field of Module pool.

In this regards, I am passing the values from the internal table to the function module "vrm_set_values" in order to display the data.

but when i am doing so, the data is not populated in the screen field when pressed F4 for the field.

While debugging, I could find the cursor is not going to the function module only....

Kindly help me in this regards !

thanks

HI,

Have you added the logic in the PAI for the event

PROCESS ON VALUE-REQUEST.
Field : field_name module source_code.  " Specify the field name and source_code is the module in which you will write the F4 logic.

This event is triggered while pressing F4 on the field .

Hello Shankar,

I have to display data in a screen field of Module pool. In this regards, I am passing the values from the internal table to the function module "vrm_set_values" in order to display the data.

First of all VRM_SET_VALUES is not released, i will avoid it unless absolutely reqd.

You can mark the module pool field's "Dropdown" attribute as either "Listbox" or "Listbox with key". In the PAI call the "F4IF_INT_TABLE_VALUE_REQUEST" & pass the internal table values to it.

Sample code can be found in the forum.

BR,

Suhas

PS: As mentiond you've to call VRM_SET_VALUES in the PBO module & not in PAI.

Hi,

All.

As suggested by all, i have used the VRM_SET_VALUES in PBO and getting the values in the required field.

I have one more issue over here, when i am selecting the value in the field the value has to get stored at some location through which i display the concerned values in the next field,

But i am unable to capture the value of the field, due to which the value in the next field is not being displayed.

Can any one help me - as in how i can store the value which has been selected intially.

Thanks in advance.

Hi,

Either you do as ramchander said or you can do the search assigned to the field in Screen painter attributes by creating a custom search help. and write the code the Search help exit (your ITAB data) ..

Thanks,

Bhargav.
