internal sales employee number range

Dear experts,

Under the same client in SAP system, different company codes can NOT have different Internal sales employee number ranges in the standard SAP, right? In other words, only one number range actiavtes for all the company codes as long as they are against the same client.

Plz corret me if I'm wrong. Many thanks.

Example:

log on SAP - client 800

client 800 has 2 company codes: 1001, 1002

Request:

sales employee under company code 1001: 10xxxxx

sales employee under company code 1002: 20xxxxx

ps. Currently HR module is not applied to client 800. Two years later, HR will be applied.
