This sections gathers all know limitations of External Data for Jira Fields
Field Options Sync
List Typehas limitation of 7000 values, but keep in mind, that around 2.000 entries the dropdown performance in the issue view starts to decrease drastically. It also depends on the machine you are testing it on, so make sure your userbase can use it properly.
Dictionary Typehas limitation of 5000 key value pairs
Cascading List Typehas a limitation of 1000 parent options
Cascading Dictionary Typehas a limitation of 1000 parents & 1000 child elements, but not more than 10.000 elements in summary.
The maximum number of fields for
Cascading List Typecombined is 100.
Field Options Sync can only sync to custom fields of Company-managed projects.
Due to memory and parsing load on our infrastructure a data source cannot load more than
15MB of data per request. When this limit is reached a request will fail to load properly. If you have a use case where more data is needed, please get in touch with us.
You can create a maximum of 70 different data sources. You can work around this limitation by using variables which makes a data source more versatile.
Email User Context
Accessing the email address of a user can work in some cases depending on their privacy settings, but will be empty in most cases. Due to the GDPR compliance you should use the
accountId of a user instead, which is a reliable identifier of a user. In case you want to map an email address from your data source to an accountId we offer a workaround in that case, but not the other way around.
JSM Request Screen
While in the create request screen only
user values can be accessed and used for dependancies. Other issue values can only be used after the ticket is created.
Due to Jira API restrictions each asset field has a limit of 10.000 asset.
As a workaround you can create multiple asset fields and combine them back to one set by configuring the context filter that you find in the custom field configuration section.
The total limit for an instance is 100.000 assets. Other apps can also consume asset space. So take this scaling limitation into account when creating your use case.
Field Number Limit
You can create a maximum of 170 different field configurations. The combined maximum of
Dictionary Type and
Cascading List Type is 100 due to app property limits.
