@harshil1712 Thank you for reply 
The reason I used SplitInBatches2 is to separate and print out the objects individually.
Convert1 items
Data of Execution 1/2 [{obj1-1},{obj1-2},{obj1-3},{obj1-4}]
Data of Execution 2/2 [{obj2-1},{obj2-2},{obj2-3}]
Final results of the “Execute Command” node.
echo $node[“SplitBatches2”].json[“item”] >> logfile.txt
{obj1-1}\n
{obj1-2}\n
{obj1-3}\n
{obj1-4}\n
{obj2-1}\n
{obj2-2}\n
{obj2-3}\n
so this is the final form of logfile.txt I expect.

And, I toggle “execute once”, but the result is the same.
Only the first data of execution (1 of 2) runs.
Please, what am I missing?
