RE: What is the purpose of MapDatasourceToEntity method in DataEntity

Hi partner,

It seems you are assigning values to the table DEntityTable, but this method is to pass the values in the table to the entity.

de.ExtraAmount = 50;
de.Description = "123";

If your entity contains these two fields.You can try to change them into:

this.ExtraAmount =50;

this.Description ="123";

Hope this helps.

RE: What is the purpose of MapDatasourceToEntity method in DataEntity

public void mapDataSourceToEntity(DataEntityRuntimeContext _entityCtx, DataEntityDataSourceRuntimeContext _dataSourceCtx) { if(_dataSourceCtx.name() == dataEntityDataSourceStr(DEntityTableEntity, DEntityTable)) { this.ExtraAmount = 50; this.Description = "123"; } super(_entityCtx, _dataSourceCtx); }

Second Way i tried

public void mapDataSourceToEntity(DataEntityRuntimeContext _entityCtx, DataEntityDataSourceRuntimeContext _dataSourceCtx) { if(_dataSourceCtx.name() == dataEntityDataSourceStr(DEntityTableEntity, DEntityTable)) { DEntityTable de = _dataSourceCtx.getBuffer(); de.ExtraAmount = 50; de.Description = "123"; } super(_entityCtx, _dataSourceCtx); }

Please tell me what wrong did i do

RE: What is the purpose of MapDatasourceToEntity method in DataEntity

Hi AX2012 r3,

There is another method called "mapEntityToDataSource".

Please have a look at the following DOC:

https://docs.microsoft.com/en-us/dynamics365/fin-ops-core/dev-itpro/data-entities/data-entity-computed-columns-virtual-fields#example-use-a-virtual-field-to-receive-and-parse-an-inbound-field

This method contains the logic of the inbound field.

And "MapDatasourceToEntity" is the opposite method to write codes about outbound fields.

The so-called outbound and inbound means the import and export of entity data.

Hope this helps.

Out of the system means for exporting . Use metadata search to find standard example.

RE: What is the purpose of MapDatasourceToEntity method in DataEntity

Hi Satish ,

Thanks for the reply.

I have seen this post

but here it is mentioned like this.

MapdatasourcetoEntity- if you want to write any custom logic while exporting data out of the system you can override this method

I donot understand "out of system".

Can you please give me an example.

Regards.

Have a great day.
