No orders (order items) could be processed

What causes this issue?

No <DS:GLOS.352A99F688E65CD5E10000009B38F974>variances</> can be
calculated for <DS:GLOS.3526C3D7AFAB52B9E10000009B38F974>manufacturing
orders</> that deliver to a
<DS:GLOS.3526B6CFAFAB52B9E10000009B38F974>nonvaluated sales order stock
</> or <DS:GLOS.3526B6F4AFAB52B9E10000009B38F974>nonvaluated project
stock</>.
In <DS:GLOS.3526BEACAFAB52B9E10000009B38F974>joint production</>,
variances are determined at the level of the order item. Variances can
only be determined for order items in joint production orders if the
following conditions are met:
All order items have final delivery status
The function <LS>distribution for co-products</> was executed before
the variances were calculated
For the orders (manufacturing orders and
<DS:GLOS.3526B6F2AFAB52B9E10000009B38F974>product cost collectors</>)
assigned to a <DS:GLOS.3526B6C7AFAB52B9E10000009B38F974>cost object
hierarchy</>, you specify how the orders are handled in the
<DS:GLOS.3526B6C6AFAB52B9E10000009B38F974>cost object type</>.
If the <LS>Control through variance key</> indicator is selected in the
cost object category, the
<DS:GLOS.3526B740AFAB52B9E10000009B38F974>variance key</> determines
how the order is handled.
For orders <ZH>with</> a variance key,
<DS:GLOS.3526B637AFAB52B9E10000009B38F974>variances</> are calculated
for the order.
For orders <ZH>without</> a variance key, variances are calculated for
the cost object hierarchy as a whole.
If the <LS>Always cost object hierachy</> indicator is set in the cost
object category, orders that are assigned to a cost object hierarchy
are always included variance calculation, regardless of whether the
assigned orders have a variance key or not.
No variances are calculated for orders that:
Do not have a variance key, or whose variance key is invalid
Are locked
Are flagged for deletion
Have a deletion indicator
Have the status "closed"
If the order has the settlement type <LS>full settlement</>, variances
between the (net) actual costs and the target costs can only be
calculated if the order has the status "delivered" or "technically
completed". If the order has settlement type <LS>periodic</> and no
goods receipt was entered for the order in the period, only remaining
variances are calculated.

System Response

No variances were calculated, or only remaining variances were
calculated.

How to fix this error?

Check your entries.
Check the order. For example, check the following:
Whether a variance key was entered
The settlement type of the order
The status of the order
If necessary, set the status to "delivered" by entering a goods receipt
and setting the <GL:"delivery_completed"_indicator>"delivery completed"
indicator</>.
If appropriate, set the status to "techically completed".
