Hi
one way:
- use a helper column
- enter the following formula (assumption: col. A stores
your part-number)
=IF(AND(LEFT(A1,1)="R",ISNUMBER(--MID(A1,2,1))),"X","")

and filter all entries with an 'X' in this helper column

I have part numbers that start with RV RW RR... However,
I only want parts that have an R and followed by a number..
R123456 R444444 I don't want any part that has a letter
after the R...
Thanks,
DJ
