Change data in existing "Choose from list" matrix

Question

Hi,
  in UI GUI->order form . When add a new order, hit "TAB" to select BP from existing list. I want to use my own sql to populate the BP list (currently the GUI defaults to return all customers).
Is there a way? I mean if I just want to change data in the matrix and let B1 continue to make the "Choose from list" form (form "10001") with my own new customer list.  Set BubbleEvent = true will just re-read all cards after I query my result.
  any help is appriciated!

Hello,
I came across the same issue with the Items Choose from List on the Sales Order screen. It is possible to load your own Choose from List form and populate the matrix using recordset objects and userdatasources. The same logic could be applied to the BP Choose from List form. The following code displays the user form and matrix items - separate code is needed to handle the selection process on this form. There maybe a faster way of acheiving this using UDTs etc but it seems to work ok.
'When user presses Tab key in Item No. column.
If pVal.EventType = et_KEY_DOWN Then
If pVal.ItemUID = "38" And pVal.ColUID = "1" And _
pVal.Before_Action = True And pVal.CharPressed = vbKeyTab Then
'Load new Choose from List form.
'This is actually an exported and edited version of the SBO form.
LoadFromXML sIIS_ITEMLIST_XML
'Populate matrix with items returned from SQL query.
'Use recordset, arrays, userdatasources.
Set oRecordSet = oCmp.GetBusinessObject(BoRecordset)
sSql = "Select OITM.ItemCode, OITM.ItemName, OITM.OnHand FROM OITM " & _
    "Where Upper(Left(OITM.ItemCode,2)) = 'B1'"
oRecordSet.DoQuery sSql
nRows = oRecordSet.RecordCount
If nRows <> 0 Then
'Array declarations.
Dim ItemCode(), ItemName(), OnHand()
ReDim ItemCode(nRows - 1)
ReDim ItemName(nRows - 1)
ReDim OnHand(nRows - 1)
'Add userdatasources to form.
oForm.DataSources.UserDataSources.Add "ItemCode", dt_LONG_TEXT, 20
oForm.DataSources.UserDataSources.Add "ItemName", dt_LONG_TEXT, 100
oForm.DataSources.UserDataSources.Add "OnHand", dt_LONG_NUMBER
i = 0
'Populate arrays from recordset.
Do While oRecordSet.EOF <> True
    ItemCode(i) = oRecordSet.Fields.Item(0).Value
    ItemName(i) = oRecordSet.Fields.Item(1).Value
    OnHand(i) = oRecordSet.Fields.Item(2).Value
    oRecordSet.MoveNext
    i = i + 1
Loop
'Bind data fields to form items.
Set oMatrix = oForm.Items.Item("7").Specific
Set oColumn = oMatrix.Columns.Item("ItemCode")
oColumn.DataBind.SetBound True, "", "ItemCode"
Set oMatrix = oForm.Items.Item("7").Specific
Set oColumn = oMatrix.Columns.Item("ItemName")
oColumn.DataBind.SetBound True, "", "ItemName"
Set oMatrix = oForm.Items.Item("7").Specific
Set oColumn = oMatrix.Columns.Item("OnHand")
oColumn.DataBind.SetBound True, "", "OnHand"
'Get data from datasources.
Dim oUItemCode As SAPbouiCOM.UserDataSource
Dim oUItemName As SAPbouiCOM.UserDataSource
Dim oUOnHand As SAPbouiCOM.UserDataSource
Set oUItemCode = oForm.DataSources.UserDataSources.Item("ItemCode")
Set oUItemName = oForm.DataSources.UserDataSources.Item("ItemName")
Set oUOnHand = oForm.DataSources.UserDataSources.Item("OnHand")
oMatrix.Clear
'For each returned record in recordset then
'add row to matrix and populate it from
'userdatasource.
For i = 1 To nRows
    oMatrix.AddRow
    oUItemCode.Value = ItemCode(i - 1)
    oUItemName.Value = ItemName(i - 1)
    oUOnHand.Value = OnHand(i - 1)
    oMatrix.SetLineData
Next i
End If
'Show form. This also sets focus to edittext field.
oForm.Visible = True
'Don't display standard SBO item list form.
BubbleEvent = False
End If
End If
