I don't think you can answer it. Which field types did you use for Sub RM Cons; Sub RM Order Q'ty; Main RM Cons; Main RM Order Q'ty? Are they tables that are related or are they not otherwise related? Do you use HSQLDB, Firebird or others?

And you can upload a sample of your DB here. To upload, edit your question.

Here you can read the base documentation.

Hello,

Just a note, don't see any reason for decimal positions in quantity fields.

Here is the Query SQL statement needed:

SELECT "Main RM Items",
       CAST(("Main RM Cons"*"Main RM Order Qty") +("Sub RM Cons"*"Sub RM Order Qty") AS NUMERIC(10,3)) "Total"
FROM (SELECT *
      FROM "Table1"
        JOIN (SELECT * FROM "Table2") ON "Main RM Items" = "Sub RM Item")

Here is what results (using the data in your question):
