#986 Handle the case that PO can’t load a record

Testcase to check if the handler will un-archive a record and the PO retries to load it, without throwing errors or exceptions.

1. Have a purchase order sales order for G000X, for P0001, and the corresponding invoice candidates

2. Open Extra, Settings

3. Change the DLM-Level at the bottom to “nur Produktiv”

4. Select the invoice candidate, and use zoom into to get to the corresponding order

5. Note the C_Order_ID of this order

6. Close the order, and in pgAdmin, do UPDATE C_Order SET DLM_Level=3 –(=archived) where C_Order_ID=your order ID;

7. Then check the DLM-Level with SELECT DLM_Level FROM C_ORDER where C_Order_ID=your order ID;:
   • => still Level 3
8. Go back to your IC, and zoom into your order again
   • => the order is displayed without errors or anything
9. In pgAdmin, check the DLM-Level again with SELECT DLM_Level FROM C_Order where C_Order_ID=your order ID;:
   • => now Level 1
   • => the System has taken back the order with Level 3, = archived, on-the-fly, without errors
10. Repeat the test, but leave the DLM-Level in Settings on “Produktivdaten und archivierte Daten”:
    • => Selects in pgAdmin show always Level 3, since the DLM-Level didn’t change and the archived data is included as well
