To display the total amount of all the open opportunities related to the account on the Account page layout while using Advanced Currency Management, the consultant should use a record-triggered flow to set the value on the account. Advanced Currency Management complicates the use of standard roll-up summary fields due to multiple currency rates. A record-triggered flow can be configured to calculate the total amount of open opportunities and update a custom field on the Account record accordingly, ensuring the displayed amount is accurate and up-to-date.
