RE: Multiply Sales locations in BC
For P&L, dimension is a good option.
The Location should be there on the Sales Invoice. If not, it is probably hidden. Use Personalize to show it.
Not sure if I understand your GL question correctly.
Depending whether you use G/L, item, resource, fixed asset, or Item Charge, BC will use the posting group to post to the correct G/L accounts. It will be based on the posting group combination. Combination A will hit GL account 1000, combination B goes to 2000, etc.
