 Then   I see error message
        "Important alert! iSell order doesn't match the external order.
         Please contact user help to handle this order."
    And order is opened as read-only
    And order lines that mismatch is shown according to BR.2
```

### S.2 Handle a mismatch order ###
```gherkin
Given   I have privilege to handle mismatched orders [2]
 When   I open the order in iSell
 Then   I see error message
        "Important alert! iSell order doesn't match the external order.

## Business Rules
### BR.1 Rules for order mismatch detection
* For each order line (article and product) verify
    - Quantity
    - Item number
* For each customer delivery verify
    - Delivery date
* Ignore any checks on cancelled order lines
* Automatically split order lines by ISOM, due to deviation, needs to be considered
* Automatically opened products by ISOM needs to be considered

[2] iSell Privilege: AllowedToModifyIsellIsomOrderMismatch

### BR.2 Order line mismatch
* Additional order lines either in iSell or ISOM
    - Show the order line in iSell
    - Possible to see message "This article is missing in the ${System} database"
* Quantity mismatch
    - Show quantity from the ISOM order
    - Possible to see message "Article quantity mismatch. ${iSellQty} in iSell and ${IsomQty} in ISOM"
