Create Hour from Text

Anonymous Maybe this and make sure you set the Data type to Whole number:

result = (TIME(LEFT([pick end],2), RIGHT([pick end],2),0) - TIME(LEFT([pick begin],2), RIGHT([pick begin],2),0)) * 60 * 24

Hi,

Please check the below measure and the attached pbix file.

Result measure: =
VAR _hourbegin =
    LEFT ( SELECTEDVALUE ( Data[pick begin] ), 2 )
VAR _minbegin =
    RIGHT ( SELECTEDVALUE ( Data[pick begin] ), 2 )
VAR _hourend =
    LEFT ( SELECTEDVALUE ( Data[pick end] ), 2 )
VAR _minend =
    RIGHT ( SELECTEDVALUE ( Data[pick end] ), 2 )
VAR _timebegin = _hourbegin * 60 + _minbegin
VAR _timeend = _hourend * 60 + _minend
RETURN
    _timeend - _timebegin

It's supposed to use PQ to conduct such a data shaping task.

let
    Source = Table.FromRows(Json.Document(Binary.Decompress(Binary.FromText("Jc3BDcAwCAPAXXj3gTFJ2lmi7L9GY3iZkxHsbUAOewyB186zLQC/DsQo4/OlXiH7qr6izIBMsvdnGZPZ5h2u09H7oP45su8FOfVPcc4P", BinaryEncoding.Base64), Compression.Deflate)), let _t = ((type nullable text) meta [Serialized.Text = true]) in type table [#"pick begin" = _t, #"pick end" = _t]),
    #"Changed Type" = Table.TransformColumnTypes(Source,{{"pick begin", Int64.Type}, {"pick end", Int64.Type}}),

    TotalMinutes = Table.AddColumn(#"Changed Type", "Total Minutes",
        each let
                begin=#time(Number.IntegerDivide([pick begin],100), Number.Mod([pick begin],100),0),
                end = #time(Number.IntegerDivide([pick end],100), Number.Mod([pick end],100),0)
            in Duration.TotalMinutes(end-begin)
    )
in
    TotalMinutes

Hi Anonymous 
Here is a sample file with the solution https://www.dropbox.com/t/OmLvgOdd6iXtXTbt

For a calculated column 

Result = 
VAR PickBegin =
    VALUE ( RIGHT ( Timing[ pick begin ], 2 ) ) + 60 * VALUE ( LEFT ( Timing[ pick begin ], 2 ) )
VAR PickEnd =
    VALUE ( RIGHT ( Timing[ pick end ], 2 ) ) + 60 * VALUE ( LEFT ( Timing[ pick end ], 2 ) )
RETURN
    PickEnd - PickBegin

For a measure

Result Measure = 
VAR PickBegin =
    SUMX (
        Timing,
        VALUE ( RIGHT ( Timing[ pick begin ], 2 ) ) + 60 * VALUE ( LEFT ( Timing[ pick begin ], 2 ) )
    )
VAR PickEnd =
    SUMX (
        Timing,
        VALUE ( RIGHT ( Timing[ pick end ], 2 ) ) + 60 * VALUE ( LEFT ( Timing[ pick end ], 2 ) )
    )
RETURN
    PickEnd - PickBegin

Thank you all for your reply. I am using ReportBuilder, testing in DaxStudio. Working on PowerBI DataSets.

And does not matter which of your solution I will choose I am receiving errors like:

"The result set of a query to external data source has exceeded the maximum allowed size"

DAX code:

DEFINE

MEASURE 'Pick Measures'[Time] = 

VAR _hourbegin =
    LEFT ( SELECTEDVALUE (  'Pick Order'[PICK Time pick begin]), 2 )
VAR _minbegin =
    RIGHT ( SELECTEDVALUE (  'Pick Order'[PICK Time pick begin] ), 2 )
VAR _hourend =
    LEFT ( SELECTEDVALUE ( 'Pick Order'[PICK Time pick end] ), 2 )
VAR _minend =
    RIGHT ( SELECTEDVALUE ( 'Pick Order'[PICK Time pick end] ), 2 )
VAR _timebegin = _hourbegin * 60 + _minbegin
VAR _timeend = _hourend * 60 + _minend
RETURN
