I would like to add a field in a BAQ containing the binary data of the “Credit Hold” flag that appears at the top of the summary page in the Sales Order Tracker module.
When I check the Customization Tool, the EpiBinding for this flag is "OrderHed.CustOnCreditHold", but I don’t see this field in the OrderHed table.
So, combining what Todd and Mark said, you’ll want to make a calculated field with Customer.CreditHold & ~OrderHed.CreditOverride (credit hold AND NOT credit override) or equivalent logic. (I actually have exactly this on a dashboard, myself.)
