In PDI, I am trying to compare data from a query(STG_FULFILLMENT_QTY_AGG) with data in Json array being sourced from a column json in Sales Queues table input. When the order_number and extid is same we compare the count(fullfilments.line_items) and quantity(which is the sum of fullfilments.line_items.quantity) . If the order_number and ext_if combination match along with count and sum above, we leave the json struct as it is. If not, we remove the refund. the code works fine in Visual Studio. I am new to pentaho and I think the code needs to be changed as only core js works with this tool.
In the Orders file are sample json structure, for example Order_number (66 in this case) need to calculate and compare the count of line items(6 in this case) along with the Quantity of items(7 in this case), if it doesn't match need to remove Object Refund along with its elements, else No Changes.
