There are two types of “hold codes”.
Processors

Processor hold codes relate to the actual Hold Code field in Invoice Entry and the associated Advanced Bridge setting: AP Hold Code
If a value exists in the Hold Code field and in Accounting System, it will display in the Posted on Hold groups. That is the only way to for a figure to display there.
Reviewer holds are done in the Approve Invoices screen, and by clicking the Place On Hold icon in the ribbon toolbar:
This relates to the Export “On Hold” Invoices Advanced Bridge setting.
If the setting is set to True, the invoice will export. If the setting is set to False, the invoice will not be exported while it is on hold.
