Import the attached function.
Save the below contents in notepad and save as f_update_dw.srf
Import it into ur pbl.

From ur code call the function as

global type f_update_dw from function_object
end type
forward prototypes
global subroutine f_update_dw (datawindow arg_dw)
end prototypes
global subroutine f_update_dw (datawindow arg_dw);Long ll_ColCount,ll_ColNo, i
String ls_ColType, ls_ColName
For i = 1 to arg_Dw.RowCount()
	ll_ColCount = Long(arg_dw.Describe("Datawindow.Column.Count"))
	For ll_ColNo = 1 To ll_ColCount
		ls_ColType = arg_dw.Describe("#"+String(ll_ColNo)+".ColType")
		ls_ColName = arg_dw.Describe("#"+String(ll_ColNo)+".Name")
		Choose Case Upper(Mid(ls_Coltype,1,4))
			Case "CHAR"
				arg_dw.SetItem ( i, ls_ColName, '' )
			Case "DECI"	
				arg_dw.SetItem ( i, ls_ColName, 0 )
		End Choose	
end subroutine

Open in new window

If you are not creating your datawindow dynamically then it would be better if you give Initial Value while designing the datawindow. Hence for any new row in datawindow will have the default value.

open datawindow > from menu.. view > column specifications > set 'Initial Value'
