Error while trying to create transport request for LPCONFIG entries

Hi

We are tying to move some LPCONFIG entries ( t.code LPCONFIG ) into a transport request from our development enviroment. While trying to assign the logical port entries to a workbench transport request type - we are getting an error

Parameter LSM not maintained in version 0033 of tp configuration

and we are not allowed to add the logical port to the transport request.

Anybody face this issue before ?
