& sub-items not displayed were corrected

What causes this issue?

&V1& sub-items were automatically corrected.
When you go to the material aggregation screen, the system sometimes
displays only the main items and not the sub-items.
If you change the main items (for example, full product items), the
system automatically changes the sub-items.
This is necessary to avoid inconsistencies.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

As a result of the sub-items being automatically corrected by the
system, the system also has to recalculate the net amount and the
invoice verification difference.
You can display the changed items by displaying all the items for the
delivery note or purchasing document.
