Which data you want to display in F4... is it from a standard table field? or you want your own FIXED data to be displayed?

Return dynpro values 


The following code shows the syntax of the FM 'DYNP_VALUES_UPDATE'. 

 
*Internal table to store dy dynpro fields and values

DATA: dynpfields  LIKE dynpread OCCURS 5 WITH HEADER LINE.
DATA: l_stepl     LIKE  sy-stepl.


REFRESH dynpfields.
CLEAR   dynpfields.
dynpfields-fieldname  = 'SCREENFIELD1-COL1'. "Screen field name
dynpfields-fieldvalue = 10.                  "New value
dynpfields-stepl      = l_stepl.             "Step loop for table controls
APPEND dynpfields.

CALL FUNCTION 'DYNP_VALUES_UPDATE'
  EXPORTING
    dyname     = 'SAPLBDT_GMGR'   "Program name 
    dynumb     = '0270'           "Screen number
  TABLES
    dynpfields = dynpfields
  EXCEPTIONS
    OTHERS     = 0.

If you want to create ur own values from a table

<b>F4IF_INT_TABLE_VALUE_REQUEST</b> Display internal table as search help (documented in SAP)

Hope this helps.

Hi,

Hi make sure that the object that you use after SELECT-OPTIONS: obj for var1 is typed properly. Either type it to a table filed for which there is a search help assignment or type it to a dataelement whose domain has a value table. Else you can directly use MATCH CODE OBJECT with a search help if you what search help can be used.
