Using OData Web Services to Modify Data

Using OData Web Services to Modify Data

You can write to the Microsoft Dynamics NAV database using an OData web service that exposes a writable page. For example, you can expose a page as an OData web service and implement it in a portal that is based on Microsoft SharePoint Online. Users of the portal can then modify the data.

Modifying Data Using OData Web Services

If an editable page is exposed as a web service, the data in the underlying table can be accessed and modified by an OData call. Microsoft Dynamics NAV supports the following OData operations for modifying data.

OData call Data impact Triggers run on page and table in Microsoft Dynamics NAV


Creates a new entity.

OnNewRecord and OnInsert


Modifies the specified existing entity.



Deletes the specified existing entity.


All calls fail if the user does not have the relevant permissions, and if the relevant property on the page, InsertAllowed, ModifyAllowed, or DeleteAllowed, is set to No.

You can use an OData web service in applications where you want users to be able to modify Microsoft Dynamics NAV data without using the Microsoft Dynamics NAV Windows client or the Microsoft Dynamics NAV Web client. For example, you can show fields from the Customer table on a mobile device or in a browser so that a user can create, update, or delete customers in the Microsoft Dynamics NAV database.

Company-Specific and Tenant-Specific OData Calls

In your implementation of the web service, you can specify which company in the database that a user can write to in the URIs that expose the web services. Similarly, you can specify the specific tenant that the change applies to if the database handles more than one tenant.

If you do not specify a company, Microsoft Dynamics NAV will identify a default company. The default company is found in the following order of sequence:

  1. The ServicesDefaultCompany setting in the Tenants.config file.

  2. The ServicesDefaultCompany setting in the CustomSettings.config file for Microsoft Dynamics NAV Server.

  3. The company in the current tenant when there is only one company.

    If the OData request is for modifying metadata, Microsoft Dynamics NAV will return the first company in the tenant database because metadata applies to all companies in the database.

If no default company can be found based on the criteria, an error message appears.
