Error during import of request among systems

Hello,

I got a new SAP system and after doing some developments, I am trying to move the objects to the old one. For that I released a request and downloaded it as text files (I found some day a programme for that in SDN). When I import the request in the old system, I get this error message:

HALT: Internal error in tw_lzh (twtrans.c line 7862). Please contact the SAP support.

what is this and how to correct the problem ??  it must be in the new system, since it works perfect from the old one into the new one. Perhaps a wrong configuration in TMS ??

thanks.
