Not every characteristic has a formula

What causes this issue?

Some features in the info structure &v1& are filled via a source field
rather than via a formula.

System Response

The formulae for the features take into account the entries from the
planning hierarchy. If a feature from the order is not contained in the
planning hierarcy, then the feature is filled with a masking symbol.
No update to the collective product allocations is carried out for
features for which no formulae are entered.

How to fix this error?

If you want to use collective product allocations, enter a formula for
every feature.
The formulae must be adopted for the info structure and its structure.
Formulae 141 to 144 can be used as references.
If you do not want to use collective product allocations (masking
indicator is empty) then you can do also do without the formulae for
the features.
