Spain
US

Create another Select List (single choice) custom field

Name: Approaches

Options:

Approach A
Approach B

Configuration

Add a Create issue post function to the workflow transition of your choice.

Issues to be created

Expression

Write an expression using this format with parsing mode in Number.

count(toStringList(%{issue.cfCountry})) * count(toStringList(%{issue.cfApproaches}))

Issue type

Choose Selected issue type.

Specific issue type

Choose Sub-task.

Parent issue

Choose Current issue.

Summary

Enter the following expression

"Country: " + nthElement(toStringList(%{issue.cfCountry}),ceil(^ / count(toStringList(%{issue.cfApproaches})))) + " / Zusatzinfo: " + nthElement(toStringList(%{issue.cfApproaches}),(modulus(^,count(toStringList(%{issue.cfApproaches}))) = 0 ? count(toStringList(%{issue.cfApproaches})) : modulus(^,count(toStringList(%{issue.cfApproaches}))))

with parsing mode set to Advanced text.

Country

Enter the following expression

nthElement(toStringList(%{issue.cfCountry}),ceil(^ / count(toStringList(%{issue.cfApproaches}))))

with parsing mode set to Advanced text.

Approaches

Enter the following expression

nthElement(toStringList(%{issue.cfApproaches}),(modulus(^,count(toStringList(%{issue.cfApproaches}))) = 0 ? count(toStringList(%{issue.cfApproaches})) : modulus(^,count(toStringList(%{issue.cfApproaches})))))

with parsing mode set to Advanced text.
