Field help (CPDEB) 

This field is used to limit the balances displayed to those where the account corresponds to the filter for the general balances, and to the BPs for the auxiliary balances.

The filter specifies the first BP or the first account from which the balance is to be inquired. It can be entered on a specific BP or a general account (or account template using the wildcards * or ?).

The ? and * characters can be used to replace respectively any character or a group of characters. For instance: 4* to only display class 4.

In the absence of the ? or * characters, the filter specifies the display start account or BP.
For instance: 4 to display the classes >= 4.
