Hello everyone !

Happy new year 2018 !!

My question is I've a workflow to capture invoice text data
from folder(DATA1). Then after capture these text data, it'll generate into invoice pdf file by each customer and then save into another folder(DATA2).

For example, if capture 100 customers invoice text data, and then it should be generated 100 customers invoice pdf files. Please pay attention number of customers are not fixed, that mean not always capture 100 customers invoice text data.

Now, I want to know is there any ways to determine all invoice text data are finished to generate pdf files ?
Because when all pdf files are finish to create, I want to add one job to copy all invoice pdf files from folder(DATA2)to another folder, e.g. folder name is DATA3.

Many thanks !
Best Regards,
