Dear colleague,
I tried to calculation update MSS ADD-ON 1.0 in Maintenance Optimizer. On step 2.3 I selected MSS ADD-ON 1.0 to add installation list and have target constellation
Then I pressed Continue button and have new wrong target constellation 
I checked system D01 in LMDB. All are OK. SAP Solution Manager 7.1 SP12
Could you please help me to resolve this issue?
With best regards,
Alexander
