Manufacturing order: Prevent issuing VHUs which are not top level

[metas-lc]

Is this a bug or feature request?

bug

What is the current behavior?

after you select a subHU (e.g. VHU) to issue, it remains there to be selected again

Which are the steps to reproduce?

1. go to Manufacturing order and select one or create a new one
2. select issue/receipt
3. select the CO product
4. select issue
5. select a VHU (so not the parent, but the child HU) and issue it
   => the VHU appears as issued on the left side (under co product) OK
   => the VHU still remains on right side to be issued NOK
6. issue it again
   => Error: org.postgresql.util.PSQLException: ERROR: duplicate key...
   Server error
   org.postgresql.util.PSQLException:
   ERROR: duplicate key value violates unique constraint "pp_order_qty_uq"
   Detail: Key (pp_order_id, m_hu_id)=(1000015, 1008815) already exists.
   SQL: INSERT INTO PP_Order_Qty
   NOK
   => it gets you out from issue
7. select the CO product and press on Issue again
   => the VHU is not only under the parent but it appears a new line with it (same error if you try to select it) NOK
   => you can also issue the parent so you can double the qty - i think NOK

What is the expected or desired behavior?

• when you issue a child, it shall disappear from the issue. I guess the parent shall also disappear if the qty is 0 (or qty cu to be updated?)
• VHU shall not get back to issues when you close it and open it again

i think we shall disallow issuing VHUs.

1. go to manufacturing order, select one and press on issue/receipt
2. select the co product and press on issue
3. select a vhu which is a child, issue it
   =>
   Error: Issuing VHUs is not...
   Server error
   Issuing VHUs is not allowed
   OK
4. as regression select both TU and VHU => works fine: both are issued and they are still parent+child OK
5. select a TU only
   => both TU and VHU are issued OK
