I had to spend some time to figure out this portion actually worked. I figured out how to make a validation, but no matter what I did, I couldn’t get it to execute. Well, turns out, you need to go to an additional transaction to turn this stuff on.
WTY_VSR_ACTIVE – Activate validation and substitutions
Once you know it, it’s pretty straightforward.

Company Code: enter in the company code this should be activated in. Note, you will need an entry for each company code.
Area: WY
Timepoint: this will be particular area within the validation and substitutions areas. 1 – 21.
Bool Class: this will be determined by entering in the Area and Timepoint.
Validation: enter in the validation name.
Valid From: valid from date
Valid to: valid to date
Sequence: sequence of the rules
Active: active or inactive.
it’s really that simple.
