How to do Total Number of Records Count in Various Nodes Should Pass to Target Field?

Simple declare a global variable in functions tab and at each node when ever you are using count fn please pass that count to a udf where it I'll add (global total=current rec cnt + global total)). Like that by end and of last node you ill be adding all rec count. Now map of that overall global count total by using another udf get global total and map it.

Two options:

1) Via graphical(its very simple and we should go with this only):

Make Records in a single queue(change the context to immediate parent node),use function "count" and pass to target element.

2) Via UDF:

Make Records in a single queue(change the context to immediate parent node) and write the logic of count via UDF.
int count=0;
for( int i=0; i<var1.length;i++)
count=count+1;
result.addValue(count);
