Error TR1102 Transformer Server detected an error in line nn in file A level specified by name or unique id was not found after restoring, synchronizing or attempting to open a model.
Resolving The Problem
1. Save the .pyg file from the client as an .mdl file and try reopening the .mdl file. If you obtain an error at a specific line number, open the mdl file in a text editor and verify that you do not have 'strange' ASCII characters at the specified line number. If you do this could indicate a corrupt model.
2. If using Oracle, confirm that the version of SQL*Net being used is 2.x. Also confirm that there is a TNSNames.ora file present on the pc. (If the previous version of SQL*Net is being used this file will not be present.) Version 1x of SQL*Net is unsupported by Oracle and will not interact successfully with Transformer.
