Hi All,
I have a business requirement related to Receivable Invoice PDF files attached to Transactions (generated using Print Receivables Transactions); If multiple version of pdf were run, the requirement is to have different file name for each file;
Now we have same file name for all pdf's; I know that we can use bursting functionality to version the file names, but I cannot upload files on transactions;
Have you encountered this requirement at another client or do you have an idea how the requirement can be configured?
