3715342 - Business Partner API is not Returning Language data for Business Partner Category Organization

The Language field appears empty when retrieving Business Partner data through the API, even though the language is maintained in the Business Partner master data for the Organization category.

SAP S/4HANA Cloud Public Edition

1. Attempt to retrieve language information for Business Partner category organizations using the API.
2. Observe that the language field is not returned.

The API does not return language information for Business Partner category organizations due to differences in the data model.

The behavior is based on the data model differences between Business Partner categories.

• When the Business Partner category is Person, the language information is stored in the Correspondence Language field of the Business Partner master data.
• When the Business Partner category is Organization, the language information is maintained at the Address level instead.

In the Business Partner app, the Language field is automatically populated from the relevant source, so this difference is not noticeable. However, when using the OData service, this distinction must be handled explicitly. For Business Partner Organizations, the language field must be retrieved from the Business Partner Address entity.

• Via navigation property: GET-/sap/opu/odata/sap/API_BUSINESS_PARTNER/A_BusinessPartner('')/to_BusinessPartnerAddress.
• or with read directly on the address entity specifying the address ID of the business partner address: GET - /sap/opu/odata/sap/API_BUSINESS_PARTNER/A_BusinessPartnerAddress(BusinessPartner='',AddressID='').
