ReqIF's limitation about a number of artifacts

Hello,

Is there any limitation or recommendation about a number of artifacts to be imported/exported?

My client uses RRC 4.0.x. They plan to import/export several tens of thousands artifacts via ReqIF. We do not use modules.

According to the following article, RRC may have some recommendation or limitation.

Exporting from Rational DOORS and importing to Rational DOORS Next Generation by using ReqIF

For the initial release of Rational DOORS Next Generation, version 4.0.1, the Rational Development team established these performance recommendations:
◾ Each module has no more than 5,000 objects.
◾ The total number of objects is about 200,000

A: ReqIF import only supports up to 3 levels of embedding.

limitation about the number of linked artifacts to be displayed in RRC 4.0.3

It looks like the number of displayable links is limited to 100 in the code, unless you are using IE7 as your browser, in which case the limit is 60

Thank you in advance.
