How many kind of macros exist to add an PostFunction?

[rafael_lopes]

Hi everyone,

I try to create a new postfunction to update a field with a date (p.ex. 14/02/2020). I try to use %%CURRENT_DATE%%, but the jira app didn't recognize it. Have 2 questions:

1) How I can realize the previous request?
2) Which kind of macros we can use?

Thanks.
