Field help (GDAACC) 

This field can accommodate accounts of "normal" or "collective" type.
When a "collective" account is used, the BP field of the structure is then accessible but not mandatory:
-if the structure is called from the journal entry, a parameter entry window is used to enter the BP code. This code is then used on the auxiliarized lines generated by the structure, unless they already had a BP.
- if the structure is called from the PB invoicing, the BP on the invoice is then used on the auxiliarized lines generated by the structure, unless they already had a BP.

When an account structure is used in BP invoice entry, the accounts parameterized as "VAT account" or "VAT/EU account" will be ignored and the journal line will not be created.
