Posted on by Alex Almeida

Hello guys,

I'm creating an integration between BC and my system, and I need to sync Jobs as Job Tasks, using OData it is possible to filter using the $filter query string.

So far so good, but I'd like to filter by most recent changes, and most of the entities have SystemCreatedAt and SystemModifiedAt fields, but I can't do

GET https://api.businesscentral.dynamics.com/v2.0/{{tenantID}}/{{env}}/ODataV4/Job_Task_Lines?$skip=999&$top=10&$filter=SystemModifiedAt gt '2022-01-01'

I got an error

{
  "error": {
    "code": "BadRequest",
    "message": "Could not find a property named 'SystemModifiedAt' on type 'NAV.Job_Task_Lines'.  CorrelationId:  56d3ae6a-0877-411a-b2ef-68a0f0b7cd27."
  }
}

Is there another way to filter by changes given a date?

Hi, There is nothing wrong with your Get statement and filter.
It's just that you didn't add the SystemCreatedAt and SystemModifiedAt fields to the page. They are in the table but not guaranteed to be in the Webservice.

I did a test with a standard Web Service.

First of all this field needs to exist on the page.

Then add filter.

api.businesscentral.dynamics.com/.../Sales_Lines_Excel gt 2022-10-03

Hope this helps.
Thanks.
