i am able to generate the sequence number based on single catergories as in picture below.

with formula : G2 = IF(B2<>B1,G1+1,G1)

this will continue sequence the box_sn, but i want machine B box_sn restart the sequence.

Answer

Based on your edit, an Excel solution would be (entered in column F):

```
=IF(A2<>A1,1,IF(B2=B1,F1,F1+1))
```
