Some columns have null values for certain records and record is not retrieved when the column is selected

I am using "Fixed Assets - Asset Depreciation Real Time" subject area, and for some Records, the "Time"."Asset Calendar Period Name" is null. 

In this case when I include the column "Time"."Asset Calendar Period Name" , the null records are dropped. 

If I remove, the records are shown. How can I handle this scenario, as I need this column in the report
