The second always overwrites the first value..Can you please provide a solution?

Hi,

could you please describe a case in more details?
Does it mean you have single Message Buffer (MB) defined for reception and if 2 messages are sent from other node, first message in the MB is overwritten?
It could happen if the MB is the matching one and is free-to-receive. 
Read Receive and Matching process chapters of the device RM.

BR, Petr
