Checksheet number in APM Foundation database and in APM Remote database is not matching. When reviewed, it was found that APM Remote exposes the Checksheet's OID number whereas APM Foundation exposes the Checksheet number. (Checksheet Number and Checksheet OID are independent Checksheet class attributes whose numbers start of aligned but can and do diverge) When we expose the OID in the APM Foundation Checksheet configurations we found that the OIDs do match between Remote and Foundation.
This issue has been reported as a bug. In the meantime, the workaround is to Open the checksheet configurations in APM Foundation and add the attribute called "Checksheet OID" beside the "Checksheet Number" attribute and rename the "Checksheet OID" column to "Remote Checksheet Number".
VSTS#20245- "APM Remote shows Checksheet OID not the Checksheet Number".
