Each Company gets a credit limit. When the A/R (the 'accounts receivable', or what has already been charged to a Company) exceeds that limit, then you get'

Direct Bill credit limit exceeded

...when posting a BD:<company>.

You have a few choices at this point:

• Increase the credit limit available to the Company (this is set and managed in the Setup area and requires 'setup' privilege to access).
• Pay down the A/R (ie, get monies from the Company to pay down the 'accounts receivable' which increases the credit limit)
• take payment in some other manner for the booking.

The Direct Bill credit limit exceeded is a warning that is intended to make sure that you don't continue to give credit to Companies that are not paying their bills.
