ARCHIVE START ,STOP, PAUSE, RESUME

ARCHIVE START ,STOP, PAUSE, RESUME

hi everyone ,
i have to create a batch report which is recorded according LOT variable
but problem is the process is different
example : started batch ABC01 (Archive Recording started) then run for 2 hours and it need to hold for 5 hours for chemical process mean time we cant Offord to keep our machine useless so we Pause the Batch ABC01 and we start another batch ABC02 and it will also run for 2 hours Then we will Pause that batch too and then resume our Pervious Batch ABC01 and complete the process and stop the batch then we continue with our 2nd batch ABC02 we will complete the batch then stop the batch so our report should generate separately for both batch but we need to Pause & Resume archive recording according to batch (Lot variable) 
i hope you all got my explanation    
please suggest me any templet or any solution for this
