I have reproduced you requirement using a different cube. The issue is the hierarchy you have chosen to show ([Date].[Calendar Semester of Year].[Calendar Semester of Year]) is part of a user defined hierarchy and you are using a level within that. The ALL member is not available here without adding it back in using UNION. Changing the hierarchy to the attribute hierarchy would be simpler.

WITH MEMBER

[Measures].[ParameterCaption] AS [Date].[Calendar Semester of Year].CURRENTMEMBER.MEMBER_CAPTION MEMBER

[Measures].[ParameterValue] AS [Date].[Calendar Semester of Year].CURRENTMEMBER.UNIQUENAME MEMBER

[Measures].[ParameterLevel] AS [Date].[Calendar Semester of Year].CURRENTMEMBER.LEVEL.ORDINAL

SELECT

{

[Measures].[ParameterCaption],

[Measures].[ParameterValue],

[Measures].[ParameterLevel]

}

ON COLUMNS,

[Date].[Calendar Semester of Year].ALLMEMBERS ON ROWS

FROM

(

SELECT ( { STRTOSET(@Year, CONSTRAINED) } ) ON COLUMNS

FROM [Adventure Works]

)

You may need to change your report dataset query to also handle the ALL item.
