rebuild the hierarchy tables I and K

Hello,

I want to rebuild the hierarchy tables I and K (e.x. /BI0/KCUST_SALES and /BI0/ICUST_SALES) of a modified 0cust_sales hierarchy (H table). Are there any functions or methods for this I can use in an ABAP program? Of course I can manually build the two tables in my program. But I donu2019t know all the relations of these two tables, so I would prefer a SAP standard routine.

Thanks in advance...
