In this section, we will learn the concept of the $filter query in SAP OData and its usage.

Supported System Version

SAP NetWeaver Gateway Release 2.0 Support Package >=03


http://<server>:<port>/sap/opu/odata/sap/<service_name>/EntitySet?$filter=ProductId eq ‘HP-101’

Business Example

The shopping site, say, Amazon is displaying all the products but you want some specific category to be displayed. So, you will apply filters (select category phones or laptops)  to display the data of your choice.


In this section, we will implement $filter on our Product Entity Set.

Step 1: After the creation of the OData service, right Click on Entity Set under Service Implementation, go to ABAP workbench.

SAP OData Implementation

Step 2:

Adjust your code for $filter query.


The filter query option is available by accessing the parameter IT_FILTER_SELECT_OPTIONS.

In the above code, we first retrieved the filter options passed from the frontend by reading IT_FILTER_SELECT_OPTIONS. And then passed the select-option range to BAPI to get the desired filtered output.

Step 3:

If we do not pass any filter option, we will get all the products from the system.

Add $filter query in OData URL and execute the service. You can add one or more filter options.

Service URL: /sap/opu/odata/sap/ZDEMO_GW_SRV_SRV/ProductsSet?$filter=Name eq ‘Notebook Basic 15.
