Generate a report to get the list of Products without customer through SEI

Dear All,

I am facing some problem to generate a report through sage enterprise intelligence.

I want information from the report is 'product without customer' but when i apply criteria/filter to the customer i.e. 'customer code=null', the output of the report is blank, not a single product is listed in the report whilst there are many products with out customer available in SAGE.

Table Used:-

ITMBPC(FACT table)

ITMMASTER

BPCUSTOMER

Please suggest how can i resolve this problem.
