How To Fix R7B149 - Key figure &1: Aggregation changed from SUM to &2

SAP Error Message - Details

• Message type: E = Error

• Message class: R7B - BW Metadata (InfoCube, InfoObject, InfoObject catalog)

• Message number: 149

• Message text: Key figure &1: Aggregation changed from SUM to &2

What causes this issue?

You have changed the aggregation of key figure &V1& from SUM to &V2&.
Changing the aggregation although a key figure is contained in
InfoProviders loaded with data is only allowed if the previous
aggregation type was SUM, the key figure has the key figure type DATE or
TIME<(>,<)> and the data type DATE or TIME.

System Response

<ZH>SAP advises against changing the aggregation as long as key figure
&V1& is contained in other InfoProviders that still contain data</>. The
correct process to change the aggregation is to first remove all data
from all InfoProviders where key figure &V1& is used. You then change
the aggregation type. After doing this, you load the data back into all
InfoProviders that you have removed data from.

How to fix this error?

If you want to change the aggregation despite the fact that other
InfoProviders containing key figure &V1& still contain data, note that
other applications and processes on top of key figure &V1& or
InfoProviders containing key figure &V1& - such as queries - might not
be executable anymore and will have to be adjusted manually.

  Data Consistency: Ensure that the data being loaded into the InfoProvider is consistent and adheres to the expected data types. This may involve checking the source data and transformation processes.
  Re-aggregate Key Figures: If necessary, re-aggregate the key figures in the query to ensure they are calculated correctly based on the desired aggregation method.
  Consult Documentation: Refer to SAP documentation or support notes related to the specific version of SAP BW or HANA you are using for any known issues or additional guidance.
