Function Module time out

Hello expert

I have faced a problem with my function module that prints an account report for a web service.

When running my function module, it gives me the error Dump timeout, through analysis I realized that it is taking a long time to read a table. however I didn't have this problem before with the same function module it took around 1 to 3 minutes to load the data, but now it does around 10 to 15 minutes.
