Can I Modify my Project key?

[Ceejie Cecilia]

initially, Issue key are set to IT + sequencing number. I want to set my Issue key to 
IT(Primary key) + (today's date) + sequencing number.

@Ceejie Cecilia here is another option that can help you:
Set automation rule - edit issue and add smart values {{issue.key}}-{{issue.created.shortDate}}
you will get KEY-000-9/5/23

Some info about representation of time and date values: Jira smart values - date and time | Cloud automation Cloud | Atlassian Support

Hi @Akbar Gulaliyev , Can you recommend what field to use?
My apologies, I'm quite new in this field.

[Akbar Gulaliyev]

@Ceejie Cecilia select the field where you want to store the issuekey+createddate (you can create just new text custom field for this).

Hi @Ceejie Cecilia 

My first question would be why does your manager want this, the date the issue is created is already stored in Jira.

What would be the benefit to show this in the issue key, if it in any case would be possible, as this is not usable in JQL.

There is no way to change the issue key as it's also used as primary key in the database where all Jira information is stored

Hi @Marc Koppelaar - Devoteam , 

I already explained it but i guess that's really our management wants. If there's no way then I'll explain it to them that it is a limitation of this system. 
BTW, Thank you for this information.

Hi @Ceejie Cecilia ,

Project Key or Issue Key?

Project Key

To change your company-managed project's key, you’ll need to contact a Jira administrator.

Only project admins can change project keys in team-managed projects.

Issue Key

You cannot manually maintain Issue Key.

Hi @Ollie Guan , I've edited my query. 
It is issue key. If there's no way I can modify the issue key (Primary + Date Today + Sequencing) I'll just inform my manager. BTW. Thank you for helping ! <3

Hi @Ceejie Cecilia !

Unfortunately, you cannot change key that's generated automatically, but you can create a field where you can combine issue key and created date.

[Ceejie Cecilia]

Hi @Akbar Gulaliyev , Can you teach me how? I'm currently implementing JIRA Service Desk in our company and the management would like to see the combination of issue key and created date.

@Ceejie Cecilia I don't have some ready script, but you can use these discussions for reference: https://community.atlassian.com/t5/Jira-Software-questions/how-to-get-issue-key-copied-to-custom-field/qaq-p/1415912 

UPD: Sorry, noticed that you have Cloud instance, so take it into account too.
