Issue/Introduction

After upgrading the CSE to 8.6, get checkout error from CSE to Toolset: 
The version of the checkout.trn file is incompatible with this Toolset (Codes /9.2.A6)

The Checkout Client error was:
CSEXI0215E Requester code page does not map to encyclopedia code page

The "C:\ProgramData\CA\Gen 8.6\logs\CSE\iefmdn.log" file (where n is a number) shows:
Req code page 1252 does not map to model code page 819.

Also when run the "%Gen86%\CSE\bin\diag.exe" command on the checkout.trn file i.e. "%Gen86%\CSE\bin\diag.exe" -f checkout.trn, the resulting diag.rpt shows the same:
Req code page 1252 does not map to model code page 819

Environment

Release : 8.6

Resolution

Updated the models codepage to 1252 (from 819 for example) using SQL to allow successful checkouts and check-ins of the model or subsets as follows: 

UPDATE DMDL SET MODEL_LANG_CODE = 1252 WHERE MODEL_NAME ='your model name';
