Hi,

In the entity add attributes with data type as enumeration and select the created enumeration .

You can also follow:

https://docs.mendix.com/refguide/enumerations/

For summing of the enumeration in the microflow get values create a list for each enum and use aggregate list function for getting the total.

https://docs.mendix.com/refguide/aggregate-list/

if this solution helps please accept the answer.

Enumerations are strings and you cannot add up strings. If you use Key values like _1, _2 you can use getKey, Substring and parseInteger to do this calculation.

Alternative is a microflow EnumXToValue with input Enum and output Integer. Use split and set the values in the end events.

call this for the 3 attributes and sum the results.

Hi Prasanna, 

The enumerations are actually predefined string values and if you will try to set the numbers are string it will store the numbers with a ‘_’ as a prefix for each number.

So, for getting the grades in integer format, either you can use the method that Chris suggested or, can pass the enum value in a microflow, and then you can create a string variable to change the ‘_2’ to 2 by using replaceall() function and the parse integer to change the ‘2 ’ into 2(int).

you can refer to the image below,

Now, you have got your numbers,

Just create an Integer variable and then you can sum up all the attributes together:

Put the value of the integer something like this,

for ex.

$Grade/Knowledge + $Grade/Relevant+ $Grade/Education

Let me know if you have any issues,

Hope it helps!!
