Background of the financial fields

[Guido1982]

Since I'm working on a module that will introduce a new inventorydetails block and will also implement the now 'standard' financial fields that live on the stock inventory modules. I will use the master-detail businessmap definition as described in the wiki, but to be able to do so I would like to know the purpose, unit (%, currency or just no.) and exact formula for each of the following fields:

• pl_gross_total
• pl_dto_line
• pl_dto_global
• pl_dto_total
• pl_net_total
• pl_sh_total
• pl_sh_tax
• pl_adjustment
• pl_grand_total
• sum_nettotal
  

I will later specify this in a readme that we could also feed back into the wiki
