SSAS MDX: Calculated member doesn't show up in Excel

I created the calculated member as described below in SSMS (not VS, therefore I did not deploy it) by selecting the command and executing it. Accessing this member in MDX works out fine. But Excel doesn't show me this measure, and I also do not see it in the cube browser. I expect to find it below the measure groups.

Question: What did I miss?

Additional question: How can I place this measure in a measure group?

CREATE MEMBER [Logistics].[Measures].[Printed] AS 
    SUM
    ( 
        {
            (
                [Pick].[Pick Method].&[4]
                , EXCEPT([Pick].[Pick Type].MEMBERS, [Pick].[Pick Type].&[A])
                , EXCEPT([Loc].[Build Zone].MEMBERS, {[Loc].[Build Zone].[All], [Loc].[Build Zone].&[G1], [Loc].[Build Zone].&[G2], [Loc].[Build Zone].&[G3]})
                , EXCEPT([Loc].[Loc Code].MEMBERS, {[Loc].[Loc Code].[All], [Loc].[Loc Code].[EXPRESS]})
            )
        }
        , [Measures].[Nb of Pick lines]
    ) ;

Executing this using this MDX-SELECT works out fine and returns a sensible result:

SELECT 
        NON EMPTY
        {
            [Location].[Build Zone].MEMBERS, [Location].[Build].[Tested]
        } ON COLUMNS
            , NON EMPTY {[Calendar].[Calendar Year].[Month].&[2019]&[August].children} ON ROWS  
    FROM [Logistics] ;
