You can define multiple function modules in one call, which will be executed each after another. Just put the number of the call in Bracket [1]/BAPI_TRANSACTION_COMMIT and [0]/BAPI_INSPOPER_RECORDRESULT (of course for all configuration parameter of the respective call).
Please note, that you cannot specify any result of the previous executed function modules to the next function module. i.e. you cannot use the result of BAPI_INSPOPER_RECORDRESULT which would be the first function module in the function module BAPI_TRANSACTION_COMMIT. For this Please use Business Objects.
