Number buffer help

Question

Hi
Sometimes we get gaps in the number range of our PO's created from EBP ie.
30000000001
30000000002
30000000010
30000000020
30000000021
and so on. But we are not sure what to do to fix the problem. This link: http://help.sap.com/erp2005_ehp_03/helpdata/EN/aa/dbc9b4b56143bb8f2ae909d7d040fa/content.htm tells about the number buffer. But what to do?
We have looked in SNRO object EINKBELEG it returns "No buffer active"?
Should we set the parameter nobuf/max_no_buffer_entries to 1?
If the solution is to set the parameter nobuf/max_no_buffer_entries to 1 will it have other consequences in the system? In this link (one number in the buffer): http://help.sap.com/erp2005_ehp_03/helpdata/EN/17/d70701912646459171d2b562d82b90/content.htm I only see benefits?
So why is the standard 1000 and not 1?
Anyone who can help me understand the behaviour of the number buffer - and solve our problem

System: SRM server 5.0 (EBP 4.0)

Answer 1

To avoid having gaps in the number range, turn buffering off using
transaction SNUM for a particular object, REQREQ (shopping carts),
for example. In that case the system reads the number from the database
strictly in order. However, please understand that buffering is
turned for performance reasons
