How To Fix BRAIN280 - Disaggregation not possible. No reference data found

BRAIN280 - Overview

• Message type: E = Error

• Message class: BRAIN -

• Message number: 280

• Message text: Disaggregation not possible. No reference data found

What causes this issue?

Data has been entered in an aggregated cell. No input-ready details have
been found for this cell. Possible reasons are:
The data is protected by characteristic relationships or data slices on
a more detailed level. The system can only recognize these restrictions
when all characteristics involved are drilled down or uniquely filtered.
No data has yet been posted and at least one characteristic is using the
access type for result values 'Posted Values'.
Data was also entered on a more detailed level at the same time, meaning
that all details are already defined, and the aggregated cell can no
longer be distributed.
For characteristics under 'Access Type for Result Values#, the query
uses the setting 'Characteristic Relationships. The system has not been
able to create any combinations for the disaggregation however. This
might be because the maximum number of combinations defined in Planning
Modeler has been exceeded.

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?

Add characteristics that are used in characteristic relationships or
data slices to the drilldown. This will allow you to identify whether
the details are no longer input-ready. Only enter data in one cell at a
time.
If the system cannot create any combinations for disaggregation from the
characteristic relationships, restrict this filter so that less data can
be processed.
