Table control

Former Member — Thu, 29 Sep 2005 20:17:09 GMT

Hi All,

I have defined a table control using wizard. Table control is based on a ABAP internal table (G_DELIVERY_DATA_ITAB

) and I have defined a explicit work area (G_DELIVERY_DATA_WA) for the internal table. I have data populated in the internal table and in the PBO I am using the following statement to move the data to the screen.

LOOP AT G_DELIVERY_DATA_ITAB

INTO G_DELIVERY_DATA_WA

WITH CONTROL DELIVERY_TAB

CURSOR DELIVERY_TAB-CURRENT_LINE.

ENDLOOP.

I can see that G_DELIVERY_DATA_WA gets the data from the internal table in the above loop ( and my screen fields are defined as G_DELIVERY_DATA_WA-VBELN, G_DELIVERY_DATA_WA-POSNR etc..) but I don't see them on the screen.

Please let me know what could be causing this problem?

Thanks,

Have you set DELIVERY_TAB-CURRENT_LINE?

Do you need to explicitly set it? I do see the current line getting incremented along with the internal table index in that loop.

you can use following psuedo code

i think u cant define screen fields with WA rather define them as G_DELIVERY_DATA_ITAB-fieldname.

LOOP AT G_DELIVERY_DATA_ITAB WITH CONTROL TCTRCL.

MODULE DISPLAY.

ENDLOOP.

MODULE DISPLAY OUTPUT.

READ TABLE G_DELIVERY_DATA_ITAB INDEX TCTRCL-CURRENT_LINE

TRANSPORTING NO FIELDS .

ENDMODULE.

Hi Chandrika,

The code you have written should work fine. I would suggest you double-check your screen fields, data declarations etc.

I changed the screen fields to point to G_DELIVERY_DATA_ITAB-fieldname and tried the below code.

Still doesn't work. I can see the internal table header line has all the data in module DISPLAY, but the screen shows up blank after this PBO code.

LOOP AT G_DELIVERY_DATA_ITAB WITH CONTROL TCTRCL.

MODULE DISPLAY.

ENDLOOP.

MODULE DISPLAY OUTPUT.

READ TABLE G_DELIVERY_DATA_ITAB INDEX TCTRCL-CURRENT_LINE

TRANSPORTING NO FIELDS .

ENDMODULE.

If you have define your screen fields as G_DELIVERY_DATA_WA, in PBO module you should write

READ TABLE G_DELIVERY_DATA_ITAB INTO G_DELIVERY_DATA_WA

INDEX TCTRCL-CURRENT_LINE.

IF SY-SUBRC <> 0. CLEAR G_DELIVERY_DATA_WA. ENDIF.

instead of

READ TABLE G_DELIVERY_DATA_ITAB INDEX TCTRCL-CURRENT_LINE

TRANSPORTING NO FIELDS .

If you have define your screen fields as G_DELIVERY_DATA_ITAB, it's useless the statament

READ TABLE G_DELIVERY_DATA_ITAB INDEX TCTRCL-CURRENT_LINE

TRANSPORTING NO FIELDS

why are u using 'transporting no fields' to your read statement?

transporting no fields will not place the required contents in the workarea and hence in the screen fields which u defined same as the work area.

Thanks all for your helpful answers. I have given points to all of you.

I did solve the problem. All I did is delete the table control from the screen and add it back using the wizard and it works now. I don't know what was causing the problem since the table control definition and PBO logic is the same as before.
