We can create records in CDS (for that matter any Data Source) from canvas app Using a FORM Control
Now let us se how can we create a record using a FORM control
a record can be created using a "FORM" control. "Form" is nothing but an object which holds a record's data. Using a "FORM" control we can create a record which is connected to a "data source" using SubmitForm function.
Eg: SubmitForm(frmStudentRegistration)Here "frmStudentRegistration" is FORM Control Name
in this post, let us see how to create a Pop-Up in Canvas App
required controls:
rectangular icon
label
buttons - 2
take a "rectangular icon" and make it screen size
update it's "Fill" - with RGBA(175, 191, 224, 0.5). It
Take another "rectangular icon" and adjust it to center
Take "label" - and add required text (Eg: "do you want to proceed?")
Take two buttons. Update text of Button1 to "OK" and other to "Cancel"
On Click of the respective control (to open the pop-up), add this expression : UpdateContext({locOpenPopup:true})
select "cancel" and "ok" button and add UpdateContext({locOpenPopup:false}) on "OnSelect" property.
add appropriate actions on "cancel" and "ok" buttons as per the requirement along with UpdateContext({locOpenPopup:false})
select the controls added above (five controls) and go to their visible property, add - locOpenPopup
Virtual Entities helps us to get data from External network without any client-side and
server-side approaches. It helps admins and system customizers in administration and
configuration.
Virutal Entities is an existing feature in D365 V 9.0, which is now part of Common Data Service (CDS).
Virtual Entity looks in D365 or CDS to user as a regular entity but contains data that is sourced from external data system
What is Virutal Entity:
Virtual Entity is an Entity in D365 platform metadata without the associated physical
tables for entity instances created in D365 V9.0 or CDS database.
How it works:
During runtime, when an entity instance is required, its state dynamically retrieved from
the associated external data source. Each virtual entity is associated with a “virtual
entity data provider” from an associated virtual entity data system.
Pros:
End users can be able to view the records created by Virtual Entities in fields, grids and search results.
System Customizers can create these virtual entities without writing any code.
Limitations:
Data retrieved by Virtual Entity is “Read-Only” (as of now).
Only Organization-owned entities are supported.
Field level security is not supported.
Auditing of data is not supported.
Once created, we cannot change a virtual entity to non-virtual entity (standard entity) and in the same way we cannot convert non-virtual entities to virtual entities once created.
Refer this document for full list of limitations.
