Hi Suhaas,
Unfortunately the class can not directly overwritten by the GenericFactory. But all instance are created in the method createReadStrategy of the class StrategyFactoryCRMImpl which you can overwrite with the GenericFactory (Alias: com.sap.wec.app.esales.module.transaction.salesdocument.backend.impl.crm.strategy.StrategyFactoryCRM)
