Can we store null value for either Process variables or Task variables?

Hi @aravindhrs,

Yes, that is possible. Do you have a specific question?

  1. Is processInstanceIds are unique across multiple tenants and multiple process definitions?

  2. Why businesskeys are not unique from the version 7.x?

Hi @aravindhrs,

Yes, instance ids are globally unique. Business keys are no longer enforced to be unique due to popular demand. It is a common use case to link multiple process instances by the same business key. You can add a database constraint if you want to ensure uniqueness in your setup.

Cheers,
Thorben
