Ingoing activity relationship in partial iteration.

What causes this issue?

In iterative activity price calculation, an activity relationship was
determined between cost center &V1&, activity type &V2& and cost center
&V3&, activity type &V4&. Cost center &V1& is not included in the
partial quantity to be iterated. The iterative network is therefore not
complete, which can lead to calculated activity prices which do not
agree with those resulting from an overall iteration.

System Response

The activity relationship is transfered, but it is not complete.

How to fix this error?

Check the activity relationship. If a manually-set activity price
existsfor cost center &V1&, activity type &V2&, the relationship is
correct. If an iterative activity price exists, you should check
whether iterative relationships were used. If in doubt, run activity
price calculation for the entire controlling area.
