Using Allen Browne's ConcatRelated function is not returning correctly.
Example:
OrderNumber Product Types
00054001021 ROUND
00054001021 WHITE
00054001121 CONCAVE
00054001121 SCORED
00054001121 WHITE
00054001221 CAPSULE
00054001221 SCORED
00054001221 WHITE
Using this:
SELECT DISTINCT YourTable2.OrderNumber, ConcatRelated("[Product Types]","YourTable2","[OrderNumber]="& "[OrderNumber]","[Product Types]",",") AS All_Product_Types
FROM YourTable2;
Is returning all of the ProductTypes for each Order Number:
OrderNumber All_Product_Types
00054001021 CAPSULE,CONCAVE,ROUND,SCORED,SCORED,WHITE,WHITE,WHITE
00054001121 CAPSULE,CONCAVE,ROUND,SCORED,SCORED,WHITE,WHITE,WHITE
00054001221 CAPSULE,CONCAVE,ROUND,SCORED,SCORED,WHITE,WHITE,WHITE
It should be:
OrderNumber All_Product_Types
00054001021 ROUND, WHITE
00054001121 CONCAVE, SCORED, WHITE
00054001221 CAPSULE, SCORED, WHITE
What am I doing wrong?

I actually solved this myself. I needed more quotation marks (") since my Order Number field is text. In case someone else has the same issue, the query should look like this:
SELECT DISTINCT YourTable2.OrderNumber, ConcatRelated("[Product Types]","YourTable2","[OrderNumber]="""& [OrderNumber] & """","[Product Types]",",") AS All_Product_Types
FROM YourTable2;
