If there is a Data Entity is F&O, and it has a unmapped field in it. And if we are using Data Events in F&O, i know that the official documentation says that virtual fields are not supported.

But, what if we populate that virtual field in the postLoad method of data entity. The Data Event trigger will run postLoad method of that data entity or not?

Thanks.

It depends. If you have a record where no field has changed (you just want to change the virtual field), there will be no data event triggered and no postLoad() called.

Hi fshaikh,

I just found some points regarding your question on the internet.

Virtual fields are not directly supported by Data Events in D365 F&O.

The postLoad method can be used to populate virtual fields, but this method does not trigger Data Events.

Data Events are triggered by changes to mapped fields in the database

While you can use the postLoad method to populate virtual fields, this does not affect the Data Events directly. If you want to ensure that some logic is executed when a Data Event occurs, you should focus on the fields that are actually mapped and persisted in the database.

public class YourDataEntity extends Common
{
public void postLoad()
{
super();

// Populate the virtual field
this.VirtualField = calculateVirtualField();
}

private YourVirtualFieldType calculateVirtualField()
{
// Logic to calculate the virtual field value
}
}

Thank you,

Hi @Raj Borad

The Data event is triggered on the mapped field change. But the values of unmapped fields are coming empty, even though there is a logic written in PostLoad method to populate them.

Does it mean Post Load method do not run?
