You can overwrite a calculated key figure for a query. However, the changes that you make remain local.
You are in the definition of a query that contains the calculated key figure. You want to further restrict this calculated key figure (by using an additional characteristic selection, for example) and change other properties on the General, Conversion and Calculations tabs.
Note that you reusable key figures within a query cannot be overwritten. A local query element is created that references the calculated key figure. You can now perform further modifications on this local query element.
Note that the technical name only relates to the local query element and not to the calculated key figure in use.
You have locally overwritten a calculated key figure in your query.
You will find the calculated key figure either in the query definition or in the outline view of the query elements. In the Calculated Key Figure directory, you can see the base reusable calculated key figure and the locally overwritten calculated key figure in the Sheet area of the query definition. Both key figures have the same technical key but have different UIDs.
