Wrong qty calculation on order with configurable after partial ship, partial invoice

[IvanPletnyov]

Preconditions

1. Magento 2 with MSI
2. Create three custom sources (source 1, source 2 and source 3)
3. Create custom stock with assigned created sources and assigned "main website".
   Priority for sources:
   1. Source 3
   2. Source 1
   3. Source 2
4. Create configurable product with two options (black and white) with assigned created sources and qty = 100.

Steps to reproduce

1. Create order with configurable with qty = 10
2. ship 3 (from source 3)
3. invoice 5
4. ship 2 (from source 1)
5. Credit memo 5
6. Ship 5 (from source 3)
7. invoice 5
8. Credit memo 5

Expected result

1. Quantity per source on ordered option on all sources equal to 100

Actual result

1. Quantity per source on Source 2 = 98; Source 3 = 92.

Additional info

1. Stock
   

2. Order
   

3. Products grid
   

4. Reservation

Please check this case when the full invoice created in the first step.

Because for me the issue looks like a bug with order status, but not as a problem with MSI computation

@maghamed I've checked this case with full invoice, bug reproduce, but we have other results on "quantity per source"

If we apply next steps:

• order for 10 items
• full invoice (10 items)
• ship 3
• ship 2
• credit memo 5 items

The order should appear in a complete status after last credit memo operation without possibility to ship any more , so that it’s an issue with order status , but not with calculations

@maghamed I've created issue on Jira https://jira.corp.magento.com/browse/MAGETWO-96456

Hi, @maghamed !
If we apply next steps:

order for 10 items
invoice 5 items
ship 5 items
credit memo 5 items
after such steps - order has status processing, but it is not possible to make shipments anymore. Do you think it's correct behavior?
