Fiori Elements Analytical table: Column label text VS Colum label text when grouped

[Alvaro_AH]

Hi gurus,

I have a Fiori Elements App which uses an Analytical table (With an underlying a CDS + Cube + Query). By using annotation @ui.presentationVariant I am able to having a default grouping, which is good, but am experiencing an undesired effect regarding column labels.

There is one field, for which I specified a custom label 'Billing Document' in the Query to overwrite the labels that inherit from the SAP data element.

Also, this field is one of the used for the the default grouping, as follows:

My issue is that when the app runs and the grouping is applied, the label shown in the column (The custom one set in the Query) does not match with the one shown in the Group (The standard one as per the data element) so it is a bit confusing.

Here I'm highlighting in green the other columns used for grouping and where the labels match, and in yellow this case in which the custom label is not being set in the grouping, only in the column.

Does somebody know If I'm missing some additional annotation? I was not able to figure it out yet.

Thanks a lot!
