As per the KBA 1662831 - Creation of New Business Partner Picking ID from Different Number Range, we have the following memo.

Now my requirement is that I want to have
10000 to 99999 for Accounts – 5 Digits
1000 to 9999 for Suppliers – 4 Digits

Now if input 1000000000 to 9999999999 in the "External Manual" will this cover both my requirement with account and supplier, when i do either excel upload or migration ?
