Hello,

SMA doesn't have any restriction but your server and php do. Please refer to the FAQ `Why some products are missing from order when I add 100+ products?` in documentation.pdf

> There is no restriction in SMA code on the number of order items. If you are having such issue, please check your php configuration file (php.ini) for `max_input_vars` and set it to higher number i.e, 20000. You might need to increase `max_input_time` and `max_execution_time` too.

Thank you
