SAP Message BRAIN486 - '&1,&2': The disaggregation settings will be ignored.

Diagnosis
You are trying to disaggregate structure element '&V1&', '&V2&' in thesame way as structure element &V3&.
<(>&<)>V3& is a formula element however and uses operator %CT or SUMCT.This is not supported.

System Response
The disaggregation settings for '&V1&', '&V2&' are ignored when thequery runs.

Procedure
During disaggregation it makes no difference whether you distribute witha structure element D or a normalized element D1 = %GT(D). Using D couldactually improve performance and reduce the likelihood of roundingerrors occurring. Normalization operators %RT, %GT and %CT shouldtherefore not be used in reference elements.
The reasons why operator %CT cannot be used in a reference element areexplained in Note 1375482.
