Hi Sayeed, 

Consider I have an entity with three attributes like below

 

You can create variables like this and store the value to your new entity attribute

Hi Saeed

As per my understanding, you want to divide operation between two entities and store results in the third entity if I am correct then you have to follow the below steps :

first, retrieve these three entities where the attribute you will use to divide, create variables, and perform operations like a divide.

 Thank you.

Thank you Stella,

I had seen this document. Please just tell me where to do these actions. In the Domain model? It does not allow me there. On Overview Page? I can not do this operation in columns either.

  1. If you make  the new attribute as “Calculated”  in the domain model, option will show up to add a microflow. You can add the microflow there. However, be careful, there is always a call one has to take “Calculated” versus “Stored”. If your field is going to be changed more often than viewed, please use this option.
  2. But, if it is going to be viewed more and changed very few times,  you need to use it as stored field You will than add microflow in the pre-commit event of the entity
