Any limitation on AP Invoice Batch as to Count or Control Amount?

We have an scheduled AP Open Interface Invoice Import program with Batch Name -'AP Import' that has been initiated earlier this year. It runs several times a day and every time the program runs, invoices are grouped into the same batch and the respective Count and Control amounts increase.

Question -

1. Is there a limitation on how many invoices can be in an AP Batch?

Based on the current setup, there will be invoices loading into this batch every day and will be spanning across multiple years. Do you see any issue with it?
