I’m working with the Dynamics 365 Business Central API and I’m stuck on filtering customer data based on an expanded field. Here’s what I’m trying to do:
I want to get only customers who use CHEQUE as their payment method. The payment method is in an expanded table called paymentMethod.
My current query looks like this:
customers?$select=*&$expand=paymentMethod($select=id,code;$filter=code eq 'CHEQUE')&$filter=paymentMethod ne null
The problem is, this query returns all customers, even those without CHEQUE as their payment method. Some have null for paymentMethod, others have different payment methods.
I’ve tried filtering with paymentMethod ne null, but it doesn’t work as expected.
Does anyone know how to properly filter expanded fields in the Business Central API? I’d really appreciate any help or suggestions on how to get only the customers with CHEQUE payment method.
I’ve worked extensively with the Business Central API, and filtering expanded fields can be tricky. The key is to use the forward slash notation in your $filter parameter. Here’s a query that should work for your case:
This approach filters customers based on the expanded paymentMethod field directly in the main query. It’s important to note that the filter is case-sensitive, so ensure ‘CHEQUE’ is spelled correctly in your system.
If you’re still encountering issues, it might be worth checking your API version and permissions. Some functionalities can vary between versions, and limited permissions could affect your results.
Let me know if this solves your problem or if you need further assistance.
I’ve encountered a similar issue when working with the Business Central API. The trick is to use the $filter parameter at the top level of your query, not within the $expand clause.
This approach filters the customers based on the expanded paymentMethod field directly in the main query. It should return only the customers with CHEQUE as their payment method.
If you’re still having trouble, double-check that the ‘code’ field in the paymentMethod table actually contains ‘CHEQUE’ (case-sensitive). Sometimes, the actual values might be slightly different from what we expect.
Also, ensure you have the necessary permissions to access the paymentMethod data for all customers. Limited permissions could lead to unexpected results.
