PDC issues and fixes

    Issues#1: PDC import is failing with the following error:

 [exec] Error during- Import

     [exec] EJBException: Unknown reason: BEA1-047E79AE2C611898D0B8; nested exception is:

     [exec]     javax.transaction.HeuristicMixedException: (PricingDB_pdc_domain, HeuristicHazard, ()) ; nested exception is: javax.transaction.HeuristicMixedException: (PricingDB_pdc_domain, HeuristicHazard, ())

     [echo] Waiting 30 seconds for import to finish.

    Solution: Change XA Retry Interval to 0 in
     

    Issues#2: Sequential Discount configuration doesn't work when discounts configured using PDC
    Solution: Set the grant_period_offset for the discounts which need sequential discount configurations:

                 update ifw_dscbalimpact set grant_period_offset=-1;

                 commit;

Issues#3: Prorate discounts for fixed discount configurations        

Solution: Add ProrateFixedDiscount entry in the discount pipeline's registry:

            ApolloDiscountModule
            {
              ModuleName = FCT_Discount
              Module
              {
                Active                   = TRUE
                DiscountDataModule       = ifw.DataPool.DiscountModelDataModule
                BalanceDataModule        = ifw.DataPool.BalanceDataModule
                AccountDataModule        = ifw.DataPool.CustomerData
                CurrencyDataModule       = ifw.DataPool.CurrencyDataModule
                DiscountMoreThanPossible = False
                TaxationMode             = 3   #[0-3] needs to in sync with 'taxation_switch' entry in pin.conf
                DiscountTrace            = FALSE
                ProrateFixedDiscount     = true
              }
            }
