How to access screen elements from another subscreen.

[Former Member]

Hi All,

Following is my requirement

I have a tabstrip in which I have a subscreen. Now after working on the subscreen the control moves to another subscreen which contains a table control. Upon a certain condition I need to enable a screen field on the previous subscreen.

Statndard transaction FB70 is used where the GL account(in the table control) is enetered and the Doc currency ( on the first subscreen on the tabstrip) field needs to be enabled after a warning message.

Any suggestions are welcome.

Thanks and Regards,

Hello,

Check if you are able to use this FM 'DYNP_VALUES_READ' in your requirment.

DATA it_dynfield TYPE STANDARD TABLE OF dynpread WITH HEADER LINE.

  CALL FUNCTION 'DYNP_VALUES_READ'
    EXPORTING
      dyname             = sy-repid
      dynumb             = sy-dynnr
*      translate_to_upper = 'X'
      request            = 'A'
    TABLES
      dynpfields         = it_dynfield.

Hope it helps.

Hi,

You need to write logic in PBO of the subscreen

DATA : wa LIKE LINE OF tab_tkreq-cols .

LOOP AT<table Control>-cols INTO wa .
   if wa-screen-name CS <field name>.
        wa-input = 1 .
        wa-active = 0 .
  endif.
MODIFY tab_tkreq-cols FROM wa .
ENDLOOP.
