I'm trying to synchronize customer to BP within R/3 system financials.

The existing customer numbers are not sequential, meaning there are missing numbers in the sequence. For instance the customers are created like this.

1

2

3

9

10

When I synchronize business partner, the BP creates the respective customer data but with sequential number range.

1

2

3

4

5

Note: I have set the external flag in the BP number range. and assigned the account group with the respective number range.

Please advise.

Thanks.
