hi friends ,

i want to display f4 help for a field in a popup. this i can do, but this popup comes based on values

i entered in other screen fields . but these values are not updated to screen values when i trigger f4.

hi,

From what i understood is the values which you choose from the F4 list is not geeting saved in the screen field.. If this is the issue please check if you have done the following..

after calling the FM 'F4IF_INT_TABLE_VALUE_REQUEST'.

IF sy-subrc EQ 0.
    IF NOT gt_matnr_returned[] IS INITIAL. <--------- Your internal table returned
      READ TABLE gt_matnr_returned INTO gs_matnr_returned INDEX 1.
      p_matnr = gs_matnr_returned-fieldval. <-------- Your screen field..
    ENDIF.
  ENDIF.

Let me know if your problem persists..

Hi Sudheer,

Just go thru this link.

Basing on one screen field value it populates the search help for other field when user presses F4.Just have a look.

It shows the usage of the above function module.

It will surely help u.

Hi,

Then use it in the AT selection screen.. First use the FM Module 'DYNP_VALUES_READ' to read the first field value and then use the internal table returned in the FM 'F4IF_INT_TABLE_VALUE_REQUEST'.. This will solve your problem...

Hi Sudheer,

Please use this function module DYNP_VALUES_READ.

Its for Reading screen field values before any user action has triggered.
