Posted on by microsoft d365

Hi experts,

I want to explore "data entity" more.

I know the basics of data entity but I don't have more understanding of data entity methods.

If you can provides some description/example about data entity methods (like how and where to use), it would be a great help.

Regards

Babita.

Which kind of methods? Standard framework methods? Your own methods? Computed column methods? OData actions?

Hi Sir,

Can you describe it in detail? There are many methods.

You can read this sequence of calls such as Odata action and DMF first to understand.

Hi Sir,

First of all, they are both data entity record levels,

insertEntityDataSource to insert data, Based on the sequence of calls provided to you, it comes after mapEntityToDataSource.
In short, mapEntityToDataSource performs write operations and mapDataSourceToEntity performs read operations. You can read this thread to learn more.

About code, you can use Metadata Search.

Hello,

Following is the purpose of the methods:

- persistEntity() - Used more as a data check and resolving those checks in data.

- initializeEntityDataSource() - Initalizes the data source to be referenced in the entity based on the action performed.

- insertEntityDataSource() - inserts data into the target table after validating the field mapping and the data to be inserted from the staging table

- mapEntityDataSource() - map the fields from the staging table to the data source used in the entity. Used more for import operations.

- mapDataSourceToEntity() - Maps the fields from the datasource with the entity fields. Used during import operations after insertEntityDataSource.

Thanks,

As you can see, most method names already indicate quite well what they do.
