Hi partner,
Sure, we will use workflow to achieve it.
First, Account entity also needs a field of the same type as the Debit field.
Go to Advanced Settings > Processes, new a worflow of Invoice entity.
Select Scope to Organization, check Record is created and Record fields change, select Debit field.
Add a step - Update record. Select Update: Customer (Account). Set Properties, select the dynamic values of Debit field to the Account field.
Activate the workflow.
In this way, when we create an invoice or update the Debit field of the invoice, Account field will be updated to the Debit field value of the invoice.
