Because multiple calls to get the value of a SIL Script Custom Field for a certain issue are inevitable, we implemented an option to generate the value only once per HTTP request. This improves performance, but might have certain side effects. For example, if the value is generated before certain other values that it depends on are modified, the result might not reflect latest updates. - Custom Field
Here you select the necessary custom field of the Data Table Information type, see example below.
- Thread Local Caching
