=====Past Due and Credit Limit Blocks and Authorizations======
Depending on your company settings in CATS, you can prevent the creation of DOs and/or invoices based on counterparties (usually customers) who are over the credit limit or have past due invoices. 
Authorizations allow you to bypass these blocks, either temporarily or indefinitely. 

Use the **Authorization Scan** to create credit limit and past due exceptions for accounts. From the main menu, go to **Accounting > Accts:Names/Addr > Authorizations**.

====Creating and Modifying Authorizations====
A list of exceptions will show on this scan. Add a new exception or edit one already created.

Exceptions can be per counterparty, per type, or even per contract, to allow a single contract to be authorized.

===Adding an Authorization====
Choose **Add** from the top menu. Select authorization type (**Past Due** or **Credit Limit Exception**), then press **Continue**.\\ 
[{{:cats:procedures:accounting:authoscan_select.png?400|Add an authorization and select the type.}}]

Enter the account and (optional) contract number. Press **Apply**.\\ 
[{{:cats:procedures:accounting:authoscan_add.png?400|Enter the account and contract number.}}]

Enter all of the information for the exception. Enter a start and end date or check box **Does not expire**, if it doesn't expire. 
Add notes or limits and press **Apply** when done.\\

The exception will be added to the scan. Choose **Edit** to revise exception, **Filter** to sort scan list and **HTML** to print scan list. **Exit** will bring you back to the home screen.
