RE: insert data to data Entity

The staging table is only used when you import/export via Data management projects.

But, you can use the entity for CRUD operations via x in exactly the same way than you would use tables.

MyDataEntity myEntity; myEntity.clea(); myEntity.MyField = 'foo'; myEntity.insert();

setBuffer and getBuffer can be used to set/get data source table buffer of data entity data source.

Here's one example: https://d365dev.com/author/d365dev/

What are you trying to achieve? Because your requirement sounds very strange.

You can easily write code to insert data tables through entities in X++, but then you don't work with staging tables. Staging tables are used when you import data to F&O or export from F&O via data management, not when you work with data entities from code inside F&O.

Regarding getbuffer() and setbuffer(), can you give us some context?

Hi skd,

You can also have a look at the blog about data entity method:

rahulmsdax.blogspot.com/.../data-entity-methods-execution-sequence.html

Getbuffer() is used to get run-time buffer of the Entity datasource, and setbuffer() is used to set the buffer of the Entity datasource.

As above said, the staging table is used in DMF, you could check the DMFGenerateSSISPackage::generateStagingData() method.

RE: insert data to data Entity

Hey Martin,

I just want to add data to my data entity since I wasn't sure how to do it so I mentioned all the tables but now I got it from your reply that how to add data.

Regarding getbuffer() and serbuffer() I meant was

Eg: HcmPositionDetail positionDetail = _dataSourceCtx.getBuffer();

what does this statement exactly mean?

Hi skd,

HcmPositionDetail positionDetail = _dataSourceCtx.getBuffer() is used to get the run time data source buffer(HcmPositionDetail).

getBuffer returns the table buffer of your data source table.

For example if you have entity MyEntity and it has data source MyTable, then if you call getBuffer method of MyTable data source, you will get table buffer of MyTable.

You can use any entities which are not marked as "Read only" in CRUD operations.

Perhaps I didn't understand what you are asking - in that case could you please explain a bit more what you mean by that question. Thanks!
