Hi All
Can I add new fields to data entities that only appear when exporting without adding fields to the table? I mean, only on the data source level, and can I control those fields to only appear on data exports and not data imports?
Regards,
Waed
You can use computed columns and virtual fields in data entities. You can make them read-only to explicitly prevent import.
Can I add Computed field to data entity through extension ?
I added field but I am able to add method to it through extension
Yes, you can. Create an extension class for the entity and add the method there.
Hi Martin,
What do yo mean by making them read only ?
You mean property of allow edit and allow edit on create to be no
Also I have question is it necessary to add computed fields to staging table?
Yes, that's what I meant. Disabling editing makes fields read-only.
You need the fields in the staging table if you want to export them through data management.
Hi goshoom
I have added more than 10 fields to DirPartyV2Entity data entity ,so I have BP warnings about number of fields in this case shall I create new table for staging and how to link it with current staging table ?
but I read this in the documentation from Microsoft "This rule verifies that no more than 10 fields were added to a table during the process of customizing or extending that table. This rule doesn't apply to staging tables."
Can you advice ? Thanks in advance.
Let's not discuss the same thing twice in parallel. You have another thread of that, Extension of staging table, so keep the discussion there.
Is there anything else that you need about the actual topic of this thread? If not, please mark verified answer(s).
