Getting duplicate values in matrix visual

For your reference.

Step 0: I use these DATA.

Table 1:

Date Product ref Quantity rqty
10/15/2023 Rack SO5658 54 30
10/03/2023 Nut SO3214 36 64
10/03/2023 Screw SO3214 20 60
10/03/2023 Sheet SO3214 50 250
09/29/2023 Sheet INV 50 300
09/29/2023 tray SO5789 41 44
09/27/2023 Rack SO3652 65 84
09/26/2023 Nut INV 100 100
09/22/2023 Sheet SO3476 36 250
09/22/2023 tray SO3476 30 85

Table 2:

Date Ref Product Quantity Lot
10/13/2023 SI2502 Tray 26 a1
10/03/2023 SO3214 Nut 36 d2
10/03/2023 SO3214 Screw 20 s6
10/03/2023 SO3214 Sheet 50 s5
10/03/2023 SI2489 Tray 100 a1
09/29/2023 SI6535 Sheet 50 s5
09/29/2023 SO5789 tray 41 a1
09/22/2023 SO3476 Sheet 36 s5
09/22/2023 SO3476 tray 30 a1
09/27/2023 SO3652 Rack 65 r4

Step 1: I add a column to both tables.

    Key_ID = [Date]&"_"&[ref]&"_"&[Product] 

Step 2: I add a relationship.

Step 3: I make a matrix.
