Scheduled Concurrent program email delivery option

HI,

We have a scheduled concurrent program running every single day at midnight for which its output is being emailed to a particular email address. However, the problem that we are facing is that not all output files are emailed, even though when the program runs successfully.

My first hint is that it has to do with the file size.

Runs that do not get emailed:

run a- retrieves 6632 pages

run b- retrieves 6252 pages

Whereas the others that do go through are:

run c- 1583 pages

run d- 3 pages

Is file size the reason why the bigger ones are not being emailed? and if so, is there any way to increase this limit?
