Hi,
Yes, I agree with you.
I have seen SAP B1 2004 until SAP B1 9.0 PL09.
None perfects and they have bugs or some application error-related issues.
The bugs can sometimes occur but sometimes not.
Some customers of SAP B1 are very very satisfied to use SAP B1 because no bugs come in their SAP B1 installation. Some of them may be not.
So, what to do is to log the support incident to SAP Global SUpport Center so that the solutions for all the bugs are prepared.
Rgds,
JM
