Error while reading ID of own business system from SLD for system <SID> and client <XYZ>

In SAP R/3 system > t-code: SLDCHECK, business system <SID>CLNT<XYZ> is visible in "Calling function LCR_BUSINESS_SYSTEMS" part. However in "Calling function LCR_GET_OWN_BUSINESS_SYSTEM" part, No corresponding business system found for system <SID> client <XYZ> while retrieving data from the SLD server. 

If you run report SXMS_TRACE_GET_OWN_BS in t-code SE38 to trace the SLD-call of function module LCR_GET_OWN_BUSINESS_SYSTEM, you get the following error: Instance //<SLD host>/sld/active:SAP_BCClient.CreateClassName="SAP_BCClient", Name="<client_id XYZ>.SystemName.<SID of SAP R/3 system>.SystemNumber.<xxxxxxxxxx>.SystemHome.<SAPDBHOST>" does not exist on SLD server
