Querying multi row variable set array

[LikeARabbit]

My use case is that I need to route approvals of a requested item based on variables within a multi row variable set (MRVS).

So far I have it working without issue by using the "startsWith" function on records that have a single MRVS row, using the code below.

answer = ifScript();

   function ifScript() {

    var mrvs;
    var itemID = current.sys_id;
    var ritmGR = new GlideRecord('sc_req_item');
    if (ritmGR.get(itemID)) {
        mrvs = ritmGR.variables.po_line_items;
    }

    var rowCount = mrvs.getRowCount();
    for (var i = 0; i < rowCount; i++) {
      var row = mrvs.getRow(i);
      var category = row.po_line_item_category;
   
   // Determine if category begins with 150
      var result = category.startsWith("150");
      gs.print(result);

      if (result == true) {
         return 'yes';
      }
      return 'no';
   }
 }

However, this doesn't work with multiple lines/rows in the MRVS. Instead it appears to query the first row and stop. 

Is there a way to instead query the entire MRVS array for a string, so that it returns TRUE if the string is found on any row and FALSE if the string is not found any any row?

I created an Article on MRVS. Please see attached if that helps you.

If it does, please mark my answer accordingly.

Thanks.
