This topic describes how to localize a report that targets different languages and cultures. A localized report displays text based on different cultures. 
Let us use the PatientHealthReport.rdlx report to demonstrate localizing report content in a specific language. 

As you may observe, the report is bound to json data sources that contain report data as well as data for localization.

The report utilizes a report parameter to enable users to choose a language out of English, Japanese, and Chinese. The Lookup function is used to fetch data from other datasets, that contain the localized text for each language. Creating such a report mainly requires report-level settings with smart design and no special features. Consider the following steps for creating such reports:  

1. We need a DataSet with all the predefined Resource Strings, to contain localized strings for each language according to the report items’ values. For example, in the attached report we have the 'ReportResourceStrings' data source, and 'ReportResourceStringDataSet' dataset with the following fields:

   Resource Strings

   Language1

   Language2

   Language3

   
   In the report, we are using Culture Code (e.g., "en-US", "ja-JP", and "zh-CN") as column names, so it is much more simplified.

   Label	en-US	ja-JP	zh-CN
   City Hospital	City Hospital	シティ病院	城市医院
   Patient Name	Patient Name	患者名	患者姓名

   
   
2. Setup a report parameter, 'pReportLanguage', to set the report language and culture code. This parameter should prompt the user to select the language.

   Name	pReportLanguage
   Type	String
   Available Values	Label	Value
   	English	en-US
   	Japanese	ja-JP
   	Chinese	zh-CN

   
   
3. Set the Language property of the report as shown below. This property also sets the Format string of the controls*.
   
   

   
   =Parameters!pReportLanguage.Value
   

   
   This should set up the culture of all textboxes etc. in the report.
   
   
4. As we set the column names as culture codes, we will use the parameter to set fields dynamically in the Lookup function.
   Sample expression to display 'Patient ID' label:
   
   

   
   =Lookup("PatientID", Fields!Label.Value, Fields.Item(Parameters!ReportLanguage.Value).Value, "ReportResourceStringsDataSet")
   

   
   
5. One might also like to add conversion values for units used in different cultures like the Resource string dataset. So, for example, for 'en-US', we would like to show temperature unit in °F and for 'ja-JP', we would like to show them in °C. For this, you can add another data set with the following fields:
   • CultureCode
   • ConversionRateToUSD
   • TemperatureUnit
   
   In our case, 'ReportCultureInfoDataSet' dataset does the conversion. The data is as shown:

   cultureCode	conversionRateToUSD	temperatureUnit
   en-US	1	°F
   ja-JP	157.3	°C

   
   Sample expression to display 'Bill Amount' value:
   

   
   =Fields!bill_amount.Value * Lookup(Parameters!pReportLanguage.Value, Fields!cultureCode.Value, Fields!conversionRateToUSD.Value, "ReportCultureInfoDataSet")
   

   
    
   Here, 'bill_amount' (default in USD) is converted based on our report language/culture parameter value.
   

   *You can also select report controls individually and set the Language property so the format changes based on the language parameter. The formatting is applied based on the following priority:      

   1. Control.Language property
   2. Report.Language
   3. Application Environment's Language property
   4. System Language settings.
      Our focus is only scoped to the report-level settings.
      
      
6. Preview the report.
   You will see a prompt to select a language. Select a language and click 'View report'.
