Populating the 2nd dropdown based on value selected on 1st dropdown

Question

Hi,
I know that there is a similar post about this in the forum but it doesn't actually show how an event for the dropdown is created. I believe this would be a script that is done within the form (transaction SFP) itself, but could I please have an example please?
I did try to take a look at the standard ISR_FORM_SPTD form but there doesn't seem to be any scripts in this form.
Thanks and regards,
Adeline.

Hi,
Am not so sure, how were unable to locate this script. Click on the dropdown and check in the Script editor. You will get the same script. Anyways, here is the script.
<i>// If the display value is used in the data DOM,
// re-assign the corresponding data value
if (this.rawValue != "" ) {
     if (this.boundItem(this.rawValue) != "") {
          this.rawValue = this.boundItem(this.rawValue);
// START OF CODE - TO RUN AFTER SELECTION HAS BEEN MADE
xfa.record.CONTROL_PARAM.ISR_EVENT.value = "CHECK";
app.eval("event.target.SAPSubmit(false);");
// END OF CODE - TO RUN AFTER SELECTION HAS BEEN MADE

// If this object exists, then we are not being rendered by the XML Form Agent
if ((Exists(xfa.host.appType)) and ($.bind.ref <> "")) then
     // Note the rawValue and try to set the selection if it is present
     // As soon as you add items the rawValue will be lost
     var CurrValue = ""
     //  Check for a null - an empty XML node will return a null
     if ($.rawValue <> null) then
          CurrValue = $.rawValue
     endif
     var Found = 0
     // the data binding may contain "$data.<root data name>" instead of $record
     var DataBinding = replace($.bind.ref,Concat("$data.",xfa.record.name),"$record")
     DataBinding = replace(DataBinding,"[*]")
     for i=0 upto xfa.record.enum_list.nodes.length - 1 step 1 do
          // Find the match.  The binding value may contain "[*]"
          // so remove them first
          var ListBinding = replace(xfa.record.enum_list.nodes.item(i).binding.value,"[*]")
          if (DataBinding == ListBinding) then
               // the first two items are the name and binding attributes, then the list starts
               if (xfa.host.version < 7) then  // add a dummy item to work around a bug in A6
                    $.addItem("a","-1")
               endif
               $.clearItems()
               for j=2 upto xfa.record.enum_list.nodes.item(i).nodes.length - 1 step 2 do
                    // The order is assumed to be display and then data
                    // if the value is null, then add the empty string
                    if (xfa.record.enum_list.nodes.item(i).nodes.item(j+1).value == null) then
                         $.addItem(xfa.record.enum_list.nodes.item(i).nodes.item(j).value,"")
                    else
                         $.addItem(xfa.record.enum_list.nodes.item(i).nodes.item(j).value,xfa.record.enum_list.nodes.item(i).nodes.item(j+1).value)
                    endif
                    if (xfa.record.enum_list.nodes.item(i).nodes.item(j+1).value == CurrValue) then

                    if (Found) then
                         $.rawValue = CurrValue
                    else
                         // otherwise: set the selection to the first item
                         $.rawValue = xfa.record.enum_list.nodes.item(i).nodes.item(3).value
                    endif
               endif
               // START OF CODE - TO RUN AFTER LIST HAS BEEN FILLED
               // END OF CODE - TO RUN AFTER LIST HAS BEEN FILLED
               break
          endif
     endfor
endif
//     END OF XFO CODE - DO NOT REMOVE OR MODIFY</i>
This should solve your problem.
