wa_cro_it-zenquiry = w_enquiry.

wa_cro_it-zlineno = sy-stepl.

wa_cro_it-zpartno = zcro_item-zpartno.

wa_cro_it-zdesc = zcro_item-zdesc.

wa_cro_it-zcustmatno = zcro_item-zcustmatno.

wa_cro_it-zmake = zcro_item-zmake.

wa_cro_it-zoem = zcro_item-zoem.

DESCRIBE TABLE it_cro_item LINES line.
  line = line + 25.
  tctrl-lines = line.

With this code you reserve 25 more lines for table control than entries in table IT_CRO_ITEM. This means that these 25 remaining rows will be empty.

As for the scrolling in PAI it will be automatically provided for manual scroll, but if you would like to use PAGE DOWN, UP buttons simply set tab_control-top_line to desired line. This way you can scroll either by one or couple rows, or by entire page.

Hi,

If you want to dynamically increase the number of lines in the table control, the you can use the code that you have written. Your code will increase the number of lines in the table control to an additional 25 lines.

Regarding the problem with your scroll bar, whenever you scroll down or scroll up the table control, the PAI is triggered. So, debug whenever you scroll down and check where the table control data vanishes. Once your PAI is triggered after scrolling down, the PBO is triggered for displaying the table control back where I am sure you wouldnt have populated data in the table control. So, try populating data from the internal table or work area onto the table control fields in the PBO as well inside a module within the LOOP...ENDLOOP.

Hello,

check if you are moving every line from table control to internal table as it should happen in PAI.

If you have not handled then after you scroll the PAI is triggering and again loading empty internal table.

Thanks,
