Random % Sample - How can I randomize the seed number to be different each time?

Question

I have utilized a random sampling workflow to generate random samples of data I have input. However, I noticed that I am locked into only using a specified set seed number in my workflow -- Therefore, if I were to rerun it on the same data again I would receive the same sample as the first run of the workflow.

Does anyone know of a way to insert a formula to randomize the "random seed" field for the deterministic output, so that I don't always end up with the same seed used if I rerun my workflow?

I'm a fan of creating a Random Field as rand() and then sitting on it.  Now I can choose to sample a number or percentage of records.

hi @AndrewLantz01

Random Sample Tool will be first choice. Do not forget to uncheck option "Deterministic Output" to unlock random seed.

If you cannot use it for some reason, try other method with reference to my WF that uses Rand() function of Formula tools. Rand() returns double value between 0 and 1, and return the different value everytime you run. The attached workflows utilize its nature to get random sampling.

Maybe we can use Numeric up Down tool?
