View source for CSupplierTransaction

A Supplier Transaction is the Equivalent of a Standard transaction done in Evolution | Accounts Payable | Transactions | Standard. Supplier transactions affect the General Ledger and the Creditors Ledger and are typically used to post payments to suppliers since invoices done here do not affect Inventory or store as a source document.

The only required values are Account, Reference and TransactionCode. Notice how the Account property is set to an instance of the Customer class. The transaction code defines whether the transaction is a debit or credit (hence the Amount is always positive) and also determines which accounts to post to in the general ledger. There are a number of default transaction codes configured in a new Evolution database (such as IN and CN), but the list is often extended, so it would be wise to make transaction codes configurable in your application. Finally, the Post method is called. This processes the transaction to the account immediately and adjusts the account balance accordingly. Other interesting fields are the transaction date (defaults to current date), description (defaults to transaction code description) and order number (empty by default).

'''The following is a example of a Supplier Transaction using the IN Transaction Type'''

<syntaxhighlight lang="csharp">
// Declare Supplier Transaction Class
SupplierTransaction SuppTran = new SupplierTransaction();
//Instance of Supplier class
SuppTran.Supplier = new Supplier("Supplier1"); 
SuppTran.TransactionCode = new TransactionCode(Module.AP, "IN");
SuppTran.TaxRate = new TaxRate("1");
SuppTran.Amount = 100;
SuppTran.Reference = "AP_Ref1";
SuppTran.Description = "StringDescription";
//Post Method to Commit Transaction
SuppTran.Post();
