เทมเพลตข้อมูล Order to Cash สำหรับการวางบิลและออกใบแจ้งหนี้

The following configuration outlines the data entities and field mappings required for the export project within the Dynamics 365 Data Management Framework. A post-processing script or tool is required to union these outputs into a single event log.

**1. Activity: Sales Order Fulfilled**
*   **Entity Name:** `Sales packing slip headers`
*   **Mapping:**
    *   `InvoiceNumber`: Use `SalesOrderNumber` as a key to later join to the invoice data and find the corresponding `InvoiceNumber`.
    *   `ActivityName`: 'Sales Order Fulfilled' (Hardcoded Value)
    *   `EventTime`: `DeliveryDate`
    *   `UserResponsible`: `CreatedBy`

**2. Activity: Invoice Generated**
*   **Entity Name:** `Sales invoice headers V2`
*   **Filter:** `InvoiceType` is not 'CreditNote'.
*   **Mapping:**
    *   `InvoiceNumber`: `InvoiceNumber`
    *   `ActivityName`: 'Invoice Generated' (Hardcoded Value)
    *   `EventTime`: `InvoiceDate` and `CreatedTime`
    *   `InvoiceAmount`: `TotalInvoiceAmount`
    *   `CustomerName`: `InvoiceCustomerName`
    *   `UserResponsible`: `CreatedBy`
    *   `PaymentDueDate`: `DueDate`
    *   `InvoiceStatus`: `DocumentState`

**3. Activities: Invoice Submitted for Approval & Invoice Approved**
*   **Entity Name:** `Workflow tracking status table`
*   **Filter:** `ContextTableName` is 'CustInvoiceJour'.
*   **Mapping:**
    *   `InvoiceNumber`: Join `ContextRecId` to `RecId` from `Sales invoice headers V2` to get the `InvoiceNumber`.
    *   `ActivityName`: Use a conditional rule, if `TrackingStatus` is 'Submitted', set to 'Invoice Submitted for Approval'; if 'Approved', set to 'Invoice Approved'.
    *   `EventTime`: `CreatedDateTime`
    *   `UserResponsible`: `User`

**4. Activity: Invoice Sent to Customer**
*   **Note:** This is an inferred event. The posting date is used as a proxy.
*   **Entity Name:** `Sales invoice headers V2`
*   **Mapping:**
    *   `InvoiceNumber`: `InvoiceNumber`
    *   `ActivityName`: 'Invoice Sent to Customer' (Hardcoded Value)
    *   `EventTime`: `PostedDateTime` (or equivalent posting timestamp)

**5. Activity: Payment Due Date Reached**
*   **Note:** This is a calculated event generated during post-processing.
*   **Source Entity:** `Sales invoice headers V2`
*   **Logic:** For each invoice where the `DueDate` has passed and the invoice is not fully settled.
*   **Mapping:**
    *   `InvoiceNumber`: `InvoiceNumber`
    *   `ActivityName`: 'Payment Due Date Reached' (Hardcoded Value)
    *   `EventTime`: `DueDate`

**6. Activity: Payment Reminder Issued**
*   **Entity Name:** `Dunning history letters`
*   **Mapping:**
    *   `InvoiceNumber`: Join from the dunning history to the customer transactions to find the related `InvoiceNumber`.
    *   `ActivityName`: 'Payment Reminder Issued' (Hardcoded Value)
    *   `EventTime`: `DunningLetterDate`
    *   `UserResponsible`: `CreatedBy`

**7. Activity: Customer Payment Received**
*   **Entity Name:** `CustPaymentJournalLineEntity`
*   **Mapping:**
    *   `InvoiceNumber`: The `Invoice` field may be populated, but often settlements are needed to link payments to invoices. This might require staging the payment data first.
    *   `ActivityName`: 'Customer Payment Received' (Hardcoded Value)
    *   `EventTime`: `ReceivedDate` or `DocumentDate`
    *   `UserResponsible`: `CreatedBy`

**8. Activity: Cash Applied to Invoice**
*   **Entity Name:** `Customer settlement`
*   **Mapping:**
    *   `InvoiceNumber`: `OffsetInvoice`
    *   `ActivityName`: 'Cash Applied to Invoice' (Hardcoded Value)
    *   `EventTime`: `TransDate`
    *   `UserResponsible`: `CreatedBy`

**9. Activity: Payment Reversed**
*   **Source Entity:** `Customer settlement`
*   **Logic:** Filter for transactions where a settlement was later reversed. This may require looking for cancellation markers.
*   **Mapping:**
    *   `InvoiceNumber`: `OffsetInvoice`
    *   `ActivityName`: 'Payment Reversed' (Hardcoded Value)
    *   `EventTime`: Reversal transaction timestamp.

**10. Activity: Credit Note Issued**
*   **Entity Name:** `Sales invoice headers V2`
*   **Filter:** `InvoiceType` is 'CreditNote'.
*   **Mapping:**
    *   `InvoiceNumber`: `InvoiceNumber`
    *   `ActivityName`: 'Credit Note Issued' (Hardcoded Value)
    *   `EventTime`: `InvoiceDate`
    *   `InvoiceAmount`: `TotalInvoiceAmount` (will be negative)
    *   `CustomerName`: `InvoiceCustomerName`
    *   `UserResponsible`: `CreatedBy`

**11. Activity: Invoice Closed**
*   **Note:** This is an inferred event based on settlement data.
*   **Source Entity:** `Customer settlement`
*   **Logic:** Use the latest `TransDate` for an invoice from the settlement data where the invoice balance becomes zero.
*   **Mapping:**
    *   `InvoiceNumber`: `OffsetInvoice`
    *   `ActivityName`: 'Invoice Closed' (Hardcoded Value)
    *   `EventTime`: The latest `TransDate` that resulted in the invoice being fully settled.
