Getting error in BRF+

Hi Experts,

In ITSM we are using BRF+ for determine the support team, by the criteria sold to party-> SAP component -> the support team as the result.

Now there is additional new requirement that is for  2 particular system we need to assign team with the system ->sap component ->the suppport team.

Is it possible to add 2 decision table to the same application. If i add the entries in the same table getting error as determine the support team method call is incorrect in the ITSM ticket log.

Or another way of do the same.

We are using solution manager 7.1 SP13 version.

Thank you in advance.

Regards
