Batch job RSVBCHCK failed during the upgrade

Hello,

I am upgrading my server to ERP 6 EHP6.
Source version is SAP ECC6 with EHP4 SP11. Upgrading to EHP6 SP5.         
During the Preprocessing phase I am stuck in the phase                 
MAIN_INIT/JOB_RSVBCHCK2. I find the following log:-        

CHECK OF UPDATE TASK ERRORS and RETURN CODE in RSVBCHCK.EV1            
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

A2EEMCEX 141 Struct. appl. "03" cannot be changed due to setup         
table -> Long text" ""MC03BF0SETUP""500" 

Can anyone help?
