Hi Team,

I have requirement from our business to do get an application or Report by running\selecting which it will execute all other reports one by one or together and get the output in a single email (ex. 4 report then 4 pdf).

Details are given below -

Available report (Ex. Custom and standard Reports)

Report 1

Report 2

Report 3

Report 4

We have thinking below options -

Opt 1. To make a custom application which will allow to search and select the record and allow to print all the output together and send an email to the user who run the report in a single email with all 4 pdf copy of report output.
