Business rule is not working as expected

Hi,

We have written a business rule but it seems not working as expected, It is running till infinity.

Below is the snippet of the rule:

SET HYBRIDBSOINCALCSCRIPT FULL;

FIX("FCCS_No Intercompany", "No Future 1", "No Future 2", "No Cost Centre", "Local_GAAP", "FCCS_Periodic")
FIX ("FCCS_No Movement")

 FIX("ST_0351002")

      "FCCS_Data Input" ( 

       IF (@IsLev("Entity", 0) )           

  (("FCCS_Net Assets"->"Total Future 1"->"Total Future 2"->"Total Cost Centre"->"Group_Final"->"FCCS_Total Data Source"->"FCCS_Intercompany Top"->"FCCS_Closingbalance"->"FCCS_Entity Total")*("FCCS_Percent Ownership"->"No Future 1"->"No Future 2"->"No Cost Centre"->"No Multi GAAP"->"FCCS_No Intercompany"->"FCCS_Total Data Source"->"FCCS_Periodic"));
