Generate file footer

H @ana00159, Can you please elaborate your requirement?

Something like I invoke a source api and I will get the count of the records that’s read and add it as part as a field at the end of the file. Basically recon information like source count and target count.

You can execute the loop using jython ,groovy or java script to count the number records read from source API .

Declare the count as global variable and store the count value  to a new variable.

Then create the file with the total number of records at the end of the file. .
