  The SAP error message RS_SMA512 indicates that there is an issue with moving a compressed fact table partition from one host to another in a distributed environment. This error typically arises in the context of SAP BW (Business Warehouse) or SAP HANA systems where data is distributed across multiple hosts.
  Cause:
  The error message "No host to move compressed fact table partition &2 from host &1 to" suggests that the system is unable to find a suitable target host to which the specified partition (indicated by &2) can be moved from the source host (indicated by &1). This can occur due to several reasons:
  
  No Available Hosts: There may not be any available hosts in the system that can accommodate the partition being moved.
  Configuration Issues: The system configuration may not be set up correctly to allow for the movement of partitions between hosts.
  Resource Constraints: The target host may not have sufficient resources (like memory or storage) to accept the partition.
  Network Issues: There could be network connectivity issues preventing communication between the hosts.
  Locking Issues: The partition may be locked or in use, preventing it from being moved.
  
  Solution:
