New BP grouping for existing BP role

Hi Media experts,

We have a requirement to add a new BP grouping for an existing role(Retailer- ISM001) which enable us to create a BP in the retailer role with a different number range. So we created new grouping and customer account group and assigned a new number range.The problem is that we created BP with the new number range but in change mode it shows only the general data.System not showing the company code and sales area datas.

Note: Integration is BP to Customer

Please give a solution

Thanks in advance,

Regards,
