REC statement returns no record

Hi Experts,

I have a scenario where I have to lookup the records from different model and push the same in current model.

My script logic works if I put a fact value 0 or something else. But if I don't have any fact value the *rec statement does not write a new record.

*REC(EXPRESSION = 1* LOOKUP(RM) , CPA_ACCOUNTS="RAW")

*REC(EXPRESSION = LOOKUP(RM) , CPA_ACCOUNTS="RAW")

*REC(EXPRESSION = %VALUE% + LOOKUP(RM) , CPA_ACCOUNTS="RAW")

I have tried all the above combinations but didn't find a solution. My question is how can i write a new record using *REC when there is no fact record available in the cube?

Regards
