For example:
I have an external table that has regions for column headings (North, South, East, West) and part numbers for row headings (Part#001, Part#002, Part#003, Part #004,...). A part number in a specific region has a cost as shown in the in the image.
Also, I have another table with the attributes Region and Part Number in FME.
I want to make a new attribute that searches the external table based on the two attributes in my FME table: region and part number and returns the cost. How can I do this?
