About selection-screen's question?

[Former Member]

Dear gurus:

I have declare a screen like below:

SELECTION-SCREEN BEGIN OF BLOCK blk_d WITH FRAME TITLE text-004.

PARAMETERS: p_matnr TYPE resb-matnr. "Material

PARAMETERS: p_bdmng LIKE resb-bdmng. "Request Qty

PARAMETERS: p_meins LIKE resb-meins.

SELECTION-SCREEN END OF BLOCK blk_d.

How to achieve such an effect：

after i input a materical code to p_matnr, display the corresponding unit in p_meins.

Actually, when the user input the qty, them want know the unit of currently material. So i want show the unit in parameter(p_meins) after them input the p_matnr,but before them input the qty.

Write the Code in AT SELECTION SCREEN OUTPUT.

When user enter the value in p_matnr and press enter the other screen will take corresponding data.

Only thing to handle here is an event.Because unless an event is triggered thos field will not get filled, if user is using F4 then it will trigger. But if he is entering manually then need to press enter.

Hello Shao,

use the following logic....

at selection-screen output on p_matnr.

select single matnr meins from resb where matnr in p_matnr.

move resb-meins to p_meins.
modify screen.

Reward If Helpful.

Hi shao,

1. User has to press ENTER,

just after entering / selecting via F4,

the material number.

2. This is one way.

3. Just copy paste.

4.

REPORT ABC.

SELECTION-SCREEN BEGIN OF BLOCK BLK_D WITH FRAME TITLE TEXT-004.

PARAMETERS: P_MATNR TYPE RESB-MATNR. "Material

PARAMETERS: P_BDMNG LIKE RESB-BDMNG. "Request Qty

PARAMETERS: P_MEINS LIKE RESB-MEINS.

SELECTION-SCREEN END OF BLOCK BLK_D.

<b>*----

---

AT SELECTION-SCREEN OUTPUT.

SELECT SINGLE MEINS

INTO P_MEINS

FROM MARA

WHERE MATNR = P_MATNR.</b>
