Hi,
we need an auto-increment custom field.
Automatically calculated in transitions (Create)
Each issue should have unique custom field value.
Example format : ITPRJYEAR-001
In the 2020
ITPRJ2020-001
ITPRJ2020-002
.....
In the 2021
ITPRJ2021-001
ITPRJ2021-002
"ITPRJ": Fixed
YEAR: Years of the current that time (when Issue created)
001: First number each year must be auto incremental
If the issue deleted, it doesn't matter unless the queue is broken
How can i solve this problem using JIRA Workflow Toolbox (Decadis) or Scriptrunner
