HI,
I'm having a senior moment.

I'm wanting to get text after the first underscore.
My data look s like this:
z_WWWWW_PR
zzz_AAAA_pk

What I'm looking for is:
WWWWW_PR
AAA_pk
I've search for a answer and found something close to what I want but it remove both underscores.
Any help appreciated.

Thanks
