CALCULATETABLE function is a power bi filter function in DAX that evaluates a table expression in a context modified by the given filters. It returns a table of values.<\/h5>\n\n\n\n
CALCULATETABLE(<expression>,<filter1>,<filter2>,\u2026)<\/pre>\n\n\n\n
<expression> is a table expression to be evaluated. A measure can not be used as expression.<\/p>\n\n\n\n
<filter1>,<filter2>.. is a Boolean expression or a table expression that defines a filter.<\/p>\n\n\n\n
Lets look at an example of  DAX using CALCULATETABLE  function.<\/p>\n\n\n\n
Here we have sample table named TransactionHistory<\/strong> which contains product details as given below.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Lets see the behaviour of CALCULATETABLE function.<\/p>\n\n\n\n
Basic use of CALCULATETABLE function<\/strong><\/p>\n\n\n\n
Lets create a table named calctable<\/strong> to filter a table records for quantity >1 using following DAX.<\/p>\n\n\n\n
CalCtable = CALCULATETABLE(TransactionHistory,TransactionHistory[Quantity] >1)<\/pre>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Once you commit DAX function, a table named as calctable<\/strong> is created in data model.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
This table is just a copy of actual table TransactionHistory<\/strong> but contains only those products for which a quantity value is greater than1.<\/p>\n\n\n\n
Lets drag a table fields into a table visual, and you can see all the products having a quantity greater than 1.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
You can also compare both tables result sets, you can clearly see that calctable<\/strong> contains only those products for which quantity value is greater than 1.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
So, using CALCULATETABLE function you can sort table records based on any specific condition.<\/p>\n\n\n\n
CALULATETABLE function with Summarize function<\/h4>\n\n\n\n
Lets modify the above DAX calculation and returns only specific columns ProductID<\/strong>, Quantity<\/strong>, and TransactionDate<\/strong> only.<\/p>\n\n\n\n
CalCtable =\nCALCULATETABLE (\nSUMMARIZE (\nTransactionHistory,\nTransactionHistory[ProductId],\nTransactionHistory[Quantity],\nTransactionHistory[TransactionDate]\n),\nTransactionHistory[Quantity] > 1\n)<\/pre>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Once you commit the DAX, you will get only those columns that you want to see as shown in below screenshot.<\/p>\n\n\n\n
\"\"<\/figure>\n\n\n\n
Using CALULATETABLE function within measures<\/h4>\n\n\n\n
You can also use CALCULATETABLE function within measure based on requirement so rather than creating a separate filtered table it can be used inside any measure.<\/p>\n\n\n\n
SumofQuantity>1 =\n\nSUMX(\nCALCULATETABLE (\nTransactionHistory,\nTransactionHistory[Quantity] > 1\n),TransactionHistory[Quantity])<\/pre>\n\n\n\n
Now once you commit the DAX, and drag the measure into card visual.<\/p>\n\n\n\n
As you can see, it returns a total quantity sum of products for which quantity is greater than1 that is 21 as shown in below screenshot.<\/p>\n\n\n\n
