For a specific Entity, if you select multiple Read related entities, and if one of them has null values for a few records, then Snap displays the following error:
An error has occurred."The EDM instance of type '[Microsoft.Dynamics.DataEntities.Person Nullable=True]' is missing the property 'EmployeesV2'." [HTTP/1.1 400 Internal Server Error]
Work-around: We recommend you either follow the above setting for the Entity or ensure all the records have data (non-null values) for the selected Read related entities.

Error

Error handling is a generic way to handle errors without losing data or failing the Snap execution. You can handle the errors that the Snap might encounter when running the Pipeline by choosing one of the following options from the When errors occur list under the Views tab:

  • Stop Pipeline Execution: Stops the current

Pipeline
  • pipeline execution if the Snap encounters an error.

  • Discard Error Data and Continue: Ignores the error, discards that record, and continues with the remaining records.

  • Route Error Data to Error View: Routes the error data to an error view without stopping the Snap execution.

Field Name

Field Type

Description

Label*

Default ValueDynamics 365 Finance and SCM Read
ExampleFinance and SCM Read

String

Specify a unique name for the Snap. You can modify this to be more specific, especially if you have more than one of the same Snap in your pipeline.

Entity*

Default Value: N/A
Example: People

String/Expression

Specify the OData entity object from which you want to read the records.

Primary key

Use this field set to specify the primary key that uniqely identifies the rows.

Key

Default Value: N/A
ExamplePartyNumber

String/Expression

Specify or select the primary key from which you want to read the record.

  • More than one primary key can exist for an Entity.

  • Ensure that you provide key-value pairs for the primary keys, which are associated with a specific entity. If you don’t, the Snap fails. For example, if you have four Primary keys in an entity, then you must pass the value for every field to fetch the results. If you use only one of the primary keys, the Snap fails.

Value

Default Value: N/A
Example0000032

String/Expression

Specify the value of the key from which you want to read the record.

Cross

Company

company

Default ValueDeselected

Expression/Checkbox

Select this checkbox if you want to fetch data apart from your default company.

You can enable the expression for this field to use input values from the upstream Snap.

Output fields

Use this field set to fetch the fields you want the Snap to display in the output.

Output field

Default Value: N/A
