That depends upon the member you are using alongwith the NONEMPTYMEMBER.
The defination and usage of NONEMPTYMEMBER is as follows:
where nonempty_member_list is one or more comma-separated member names or calculated member names from the same dimension as the formula or calculated member.
Use a single NONEMPTYMEMBER property clause at the beginning of a calculated member or formula expression to indicate to Essbase that the value of the formula or calculated member is empty when any of the members specified in nonempty_member_list are empty.
Hope this helps.....
Further to Amit's post... ...it might help to post the formulas.
