Question

用户在应用促销代码时收到此错误，我已经进行了大量研究但未找到此错误的原因。

Environment是IBM Websphere Commerce 7，DB2。

com.ibm.commerce.order.calculation.FinalizeDiscountCalculationUsageCmdImpl performExecute CMN3201E: 
An unknown error occurred while the Rules System was processing.. 
com.ibm.commerce.marketing.promotion.runtime.PromotionRuntimeException: 
com.ibm.commerce.exception.ECApplicationException: 
A generic promotion system exception occured.  The exception is as follows: 
"The XPath query expression "/PX_CDUSAGE[CODE_FOR_REFERENCE=]" is invalid."
at com.ibm.commerce.marketing.promotion.runtime.PromotionArgument.finalizePromotionArgument(PromotionArgument.java:868)
at com.ibm.commerce.order.calculation.FinalizeDiscountCalculationUsageCmdImpl.performExecute(FinalizeDiscountCalculationUsageCmdImpl.java:104)
at com.ibm.commerce.command.ECCommandTarget.executeCommand(ECCommandTarget.java:157)
at com.ibm.ws.cache.command.CommandCache.executeCommand(CommandCache.java:332)

我一直试图弄清楚这个错误的根本原因，因为2天但找不到任何东西。非常感谢任何帮助。

Answer 1

xpath表达式已完成。它应该是这样的：

"/PX_CDUSAGE[CODE_FOR_REFERENCE='forgotten']"

XPath查询表达式＆＃34; / PX_CDUSAGE [CODE_FOR_REFERENCE =]＆＃34;是无效的
