Hi everyone, 

Anyone know the params required for 

application.RunOperation(PosisOperations.ExpenseAccounts,obejctParms) 

application.RunOperation(PosisOperations.IncomeAccounts,obejctParms) 

 I need to create some Expense or Income accounts using code.

Is this kind of parametrization documented anywhere?

Thanks in advance

Thanks in advance
