 (function() {

    var grid = apex.region("myGrid").widget().interactiveGrid("getViews", "grid"),

        model = grid.model,

        rowNum = 0,

        p16CatId = $v("P16_CAT_ID"); // Get the value of P16_CAT_ID

    model.forEach(function(record, index) {

        rowNum++;

        var rowNumStr = rowNum.toString().padStart(5, '0'); // Ensure rowNum is 5 digits with leading zeros

        var pls = p16CatId + rowNumStr; // Concatenate P16_CAT_ID and the formatted rowNum

        model.setValue(record, "ICODE", pls);
