You need to add the script to populate event data on the form. Which code segment should you use?

  1. formContext.data.addOnLoad(myFunction)
  2. formContext.data.removeOnLoad(myFunction)
  3. formContext.data.entity.addOnSave(myFunction)
  4. addOnPreProcessStatusChange
  5. formContext.data.isValid()

Answer(s): A

Explanation:

data.addOnLoad adds a function to be called when form data is loaded.
Syntax: formContext.data.addOnLoad(myFunction)
The function to be executed when the form data loads. The function will be added to the bottom of the event handler pipeline.
Incorrect:
Not D: Wrong syntax. Need a function parameter.
Note: addOnPreProcessStatusChange adds a function as an event handler for the OnPreProcessStatusChange event so that it will be called before the business process flow status changes.

Syntax: Syntax -
formContext.data.process.addOnPreProcessStatusChange(myFunction);
The function to be executed when the business process flow status changes. The function will be added to the start of the event handler pipeline.
Not E: IsValid() gets a boolean value indicating whether all of the form data is valid. This includes the main table and any unbound columns. If the form has empty, required columns on it, control-level error notifications is shown.
Description: true if all of the form data is valid; false otherwise.

You have a Common Data Service entity and a model-driven app. The model-driven app integrates with an external system.

You plan to run business logic each time the model-driven app creates a record. Running business logic must not negatively affect model-driven app users.

You need to implement the business logic. What should you use?

  1. Synchronous plug-in registered in the PreOperation stage
  2. Synchronous workflow
  3. Asynchronous plug-in registered in the PostOperation stage

Answer(s): C

Explanation:

The asynchronous service executes long-running operations independent of the main Microsoft Dataverse core operation. This results in improved overall system performance and improved scalability.

Box 2: Yes
ContinueOnError: When true, continue processing the next request in the collection even if a fault has been returned from processing the current request in the collection. When false, do not continue processing the next request.

ReturnResponses: When true, return responses from each message request processed. When false, do not return responses.
When false, the Responses collection will not be empty if errors are returned. If errors are returned, there will be one response item in the collection for each processed request that returned a fault and Fault will be set to the actual fault that occurred.

Box 3: No

Box 4: Yes
For example, in a request collection that contains six requests where the third and fifth request return faults, the following table indicates what the Responses collection would contain.
ContinueOnError=true, ReturnResponses=false: 2 response items: 2 have Fault set to a value.
