Cash VAT Management/Technical Documentation

Contents

Introduction

The Cash VAT management development is split in Core and an external module called Cash VAT Management, that can be installed from the Central Repository.

All the business logic is directly implemented in Core, and the external module only contains the User Interface artifacts (Tabs and Fields). This is an easy way to hide this functionality for the clients that won't use it.

Modify Triggers

C_Tax_TRG

C_InvoiceLine_TRG

Modify PL/SQL functions

C_Order_Post

C_Invoice_Post

C_GetTax

In case of an exception, the callout will call a new pl/sql function (c_gettax_override_cashvat), which will be based on the c_gettax, but that will override the organization/business partner cash VAT configuration. Otherwise the behaviour will be the same. This way we ensure we don't break the API in any manner.

New PL/SQL functions

C_GetTax_Override_CashVAT

Java

Modify Callouts

SE_Invoice_BPartner

SE_Order_BPartner


SL_Invoice_Product

SL_Order_Product

Accounting engine

The usage of the Cash VAT transitory accounts forces us to modify the accounting engine:

Modify DocInvoice

Modify DocFINPayment

DocFINFinAccTransaction

DocFINReconciliation

Open Topics

How and when to create the Invoice Cash VAT documents?

VMA: we have different possibilities to automatically create the document:

VMA: We need also to decide when the document should be created (and this will give us the way to implement it). For example, shall we create the document when the payment is created or posted, or when the transaction is created or posted, or when the reconciliation is created or posted? Alternatively, should we create a configuration in the Payment Method to configure this behaviour?


ANSWER: The C_Invoice_Tax_CashVAT records will be created when processing the payment. However the accounting entries that represents the movement of the cash VAT amounts from the transitory accounts to the final ones will be executed when the payment/transaction/reconciliation is posted

Is it necessary to modify the Orders Accounting?

ANSWER: No, it is not necessary

Is it necessary to modify the Payment, Transaction or Reconciliation accounting?

VMA: I don't think it's necessary since these documents don't take taxes into account

ANSWER: It's necessary to move the cash VAT amounts from the transitory accounts to the final ones in the same moment where the payment, transaction or reconciliation have been posted
