In fact I backup the database containing all the transactions.

I then edited the resulting sql file and removed the non desired Insert statements.
I then restore the database.

It seems to work well.

Thanks,

I suppose it would entail:
Start a transaction
If a complete reset is required
  log and set opening document numbers

For records between start date and end date
  backup and delete debtor transactions, details and tax
  backup and delete supplier transactions, invoice items and invoice tax
  backup and delete POs, details and purchase data
  backup and delete WOs and associated data
  backup and delete Goods Received
  backup and delete stock levels
  backup and delete stock movements
  backup and delete supplier allocations
  backup and delete bank, GL and budget transactions

commit the transaction

Non-trivial - particularly the design and testing phases to make sure that no aspect of the system was compromised.

Do I really have to start over ? creating users and others structure or is there somthing I can do to make it simple ?

Thanks

Therefore I will start a new company  and use a pre-defined chart (I notice a french canadian one) ?

By the way, I'm testing FrontAccounting for the accounting of our association, and I have to tell you that it is a great product, really.

Thanks,

I then made many changes in the parameters, groups, names, etc.

Now I would like to keep the structural changes, and remove all transactions in order to do real work.

Is it possible, or do I have to start "fresh" ?

Thanks
