SAP buffer for Customer Account Group (number range skipping)

Question

Dear Experts,
When creating new customer for Account Grp = TRDL for my company, I find out that the number range always skip and this problem continues. Someone told me to check it out if the problem might comes from buffer. In Tcode = SNRO (Object = DEBITOR) I find out that buffer setting = 5.
The Question is how can I check if this buffer rate is compatible with my SAP environment? or which rate is more compatible and help solve the problem of number range skipping?
If anybody have some suggestion please feel free to contribute it.
Thank you very much

Hi,
in SNRO, take out the flag for
"Main memory buffering".
SAP recommends:
Dependencies
When buffering number intervals, gaps may result in number assignment. Buffering is therefore not possible for applications, which require continuous number assignment.
What happens is that the system loads consecutive numbers into the buffer, in your case these are five consecutive numbers. When you create customers and do not use all the numbers already in the buffer, the numbers remain open. Example: You start XK01 for customer creation, create three customers and then logoff. You have two open numbers remaining. Numerical example: 1, 2, 3 have been used, 4 and 5 have been reserved, but are open.
When invoking XK01 again after subsequent log-on, the system pulls the next five numbers into the buffer. Since 1,2,3,4,5 were already taken (for the previous buffer), the next buffer goes from 6 to 10.
Numbers 4 and 5 will never be used, the practical consequence of that are the number gaps that you have noticed.
Hope this helps.
