RE: The error message appears when the maximum number of customers (4500) is reached while printing statements. This limit is to prevent any crashing when creating statements.

First, I don't think that's the actual case. Based on other posts here, it seems to happen simply when there are more than 4500 customers - no matter how many will actually get a statement.

Second, there is no reason for a crash, no matter how many statements are printed. Intuit should just fix the crash, not cripple the feature to avoid it.

RE: In addition, since you're only creating statements for specific number of customers but got an error, @benaaco's suggestion about choosing the Multiple Customers option would be a great workaround.

OK, so let me get this straight.  I have 45,000 customers on my customer list and need to send statements to everyone who purchased something in the last quarter, about 750 customers.  And you think that I can somehow figure out who they are and manually select them when creating statements? Really? That's your idea of a great workaround?  If so, what's you're ideas of a just-OK workaround? Perhaps manually hand-writing the statements? Or is that also a great workaround?

RE: This approach lets you select specific customers to avoid data issues while doing this task.

That sounds scary!  And also not anything anyone complained about, What are the scary data issues we're that we are avoiding by manually selecting customers?
