# PSL+ Integration – Overview

The **PSL+ Integration** connects Digital Purchase Order (DPO) with PSL+ to streamline Purchase Order and invoice workflows between both systems. Purchase Orders can be created and approved in DPO while relevant P.O. information, accounting codes, suppliers, and status changes are synchronized with PSL+. If **AP Automation** is enabled, fully approved invoices can also be transferred from DPO to PSL+.

### **Good to Know**
For **AP Automation**, synchronization is primarily managed from DPO to PSL+.
Invoice-to-P.O. matching changes, especially **unlinking**, should always be performed in **DPO**. Changes made directly in PSL+ are not automatically reflected back in DPO and may lead to inconsistent data.
For synchronization issues, first check the **Sync Status displayed directly on the P.O. or invoice**. In many cases, DPO will show the reason the document has not synchronized and what needs to be corrected.

### **What Does the PSL+ Integration Synchronize?**

Depending on your configuration, DPO can receive accounting information configured in PSL+, including:

* **Chart of Accounts (COA)**
* **Company Codes**
* **Production Codes**
* **Set Codes**
* **Series Codes**
* **Location Codes**
* **Insurance Codes**
* **Free Field Codes**
* **Currency Codes**

Currency ISO codes in DPO correspond to the Currency Codes configured in PSL+.

### **Purchase Order Workflow**

When a Purchase Order is created in DPO, it is synchronized with PSL+ and its PSL+ status changes as it moves through the approval process.

For example:
* A P.O. awaiting approval in DPO appears as **W – Awaiting Approval** in PSL+.
* Once finally approved, the P.O. becomes **O – Open** in PSL+.
* Amendments, closing, reopening, declining, and voiding can also update the corresponding P.O. in PSL+.

### **Invoice Workflow with AP Automation**

If **PSL+ AP Automation** is enabled, invoices can be received, validated, matched, and approved in DPO.
Once an invoice is fully approved, it is automatically exported to PSL+ and creates an **A/P Entry transaction** with an **I – Imported A/P** status.

###### P.O. Statuses in PSL+

As a Purchase Order progresses through DPO, its status is automatically updated in PSL+.

| DPO Status / Action | PSL+ Status |
| ---- |
| Pending / Awaiting Approval | **W – Awaiting Approval** |
| Final Approved | **O – Open** |
| Approved P.O. amended | **N – Needs Reapproval** |
| Closed | **C – Closed** |
| Declined | **R – Rejected/Declined** |
| Voided | **V – Voided** |
