The sourceLabel field has incorrect value "???JOBS2WEB???" in OData API response.
SAP SuccessFactors Recruiting Management
We will fix the issue in 2H 2021 release (b2111).
Please note that, to be consistent with the Applicant Profile and Ad-hoc Reports we have kept the same sourceLabel for Odata API as well. The label will be "Jobs2Web" for sourceID= 8 and not "Recruiting Marketing".
