Create a Salesforce Formula Field (Text) to reference the Account Address (we have a similar use case on the following documentation https://apps-docsappfire.servicerocket.com/salesforce-jira/mapping-account-name-to-a-jira-custom-fieldatlassian.net/wiki/spaces/CSFJIRA/pages/470758418/Mapping+Account+Name+to+a+Jira+Custom+Field?src=search )
In the syntax, referencing the Account Address throws an error due to incompatibility
Therefore a workaround using custom syntax like this article can be used (We used “, “ instead)
Code Block Account.BillingStreet + ", " + Account.BillingCity + ", " + Account.BillingState + ", " + Account.BillingPostalCode + ", " + Account.BillingCountry
Map the new formula field to your Jira custom field.
The field value should be synced accordingly.
