CLI0550 A Logon parcel was not present as expected
A Logon parcel is not the first parcel in a Logon or Connect request.
The error is detected by TDP. This error should not occur for a CLIv2 application since CLIv2 itself constructs the parcels for the Connect function.
Collect diagnostic information (including the memory dump and TDPSNAP output, if any) and contact Customer Support personnel.
