Create a custom number field in JIRA data center

Tony Nasr

Hello,

I need to create a custom field of type Number using the JIRA Java API with the following requirements:

• The field should accept only numeric values with configurable maximum and minimum fractional digits.
• It should also enforce a maximum and minimum numeric value.
• These constraints (min/max values and fractional digits) should be configurable through the field's configuration.
• The field should be visible at the "Estimation Statistic" in the Jira boards.
• The field should NOT use Jira-core

Could you please guide me on how to implement this?

Best regards,
Tony

Hi @Tony Nasr 

welcome to the Community and thank you for your question.

The short answer here is: that is not possible by default. 
To achieve this, you will need to have a third party app like Jira Misc Custom Fields or you could also use a default number field and create a custom validator using apps like ScriptRunner or Jira Misc Workflow Extension. 
Both of these solutions aren’t quite straightforward and will require some Groovy Scripting and RegEx Knowledge.

hopefully it at least points you into the right direction
