Features used to implement the example

• Project Properties
• Read a project property
• Mathematical and date-time expression calculator
• Update issue fields
• Set or create project property

Example: Using project properties to calculate custom sequence numbers

In this example, a custom identifier "Approval Code" is added to issues by using a project property and different custom fields.

The code that will be created is a combination of a specific number (sequence number), the fiscal year (custom field) and abbreviation of a department and will look like this:

003/2018-2019/DEV

Configuration items needed are:

• Project property "sequenceNumber"
• Custom Text Field "Department"
• Custom Text Field "Fiscal Year"
• Custom Text Field "Approval Code"

Setting the project property

Setting a project property can be done via the project settings → Details.

A valid expression is: {sequenceNumber=0}

Adding multiple post functions

When executing the transition, the current value of "sequenceNumber" is stored in an ephemeral field with the Read a project property post function.

Name of project property is: sequenceNumber

Incrementing the "sequenceNumber" by one is done with a Mathematical and date-time expression calculator post function.

Formula is: {00058} + 1

Note that:

• {00058} is the field code for Ephermeral Number 1

Formatting the "sequenceNumber" is done with a Set a field as a function of other fields post function: This ensures that the sequence number is always a 3 digit number, e.g. "3" is formatted to "003" and "10" to "010".

Setting rules are:

[length(%{00058}) = 1]00%{00058}
[length(%{00058}) = 2]0%{00058}
[true]%{00058}

Note that:

• %{00058} is the field code for Ephemeral number 1

Finally, the "Approval Code" is composed with an Update issue fields post function.

Text to be parsed (in advanced mode) is: %{00061} + "/" + %{10420} + "/" + toUpperCase(substring(%{10421}, 0, 3))

Note that:

• %{00061} is the field code for Ephermeral string 1

• %{10420} is the field code for custom text field "Fiscal Year" (this field code might differ on your instance)
• %{10421} is the field code for custom text field "Department" (this field code might differ on your instance)

In order to keep the "sequenceNumber" in sync, a final Set or create project property post function is added.

Once configured, the transition will look like this:
