Picking Tickets - Credit Hold (8.03)

Anyone find a could way to prevent Picking Tickets form Picking if the
Order is on Credit Hold.

I create a Crystal ODBC Shipping Schedule report that will because I
could link Customer to OrderHed and create a Formula that If
{Customer.CreditHold} = TRUE AND {OrderHed.CreditOverride} = FALSE
Then "CREDIT HOLD" which we are informing the Shipping Person to pull
the Picking Tickets that are on Credit Hold but we would rather not see
them print at all.

But I cannot get the Customer Table to link properly when adding it to
the Data Definition to get to the Customer.CreditHold field.
