我需要根据已映射到它的PO来获取CONTRACTLINE详细信息。所以我在PO上创建了一个Object启动点，它将在“UPDATE”期间触发，但是CONTRACTLINE上的getMbo（0）是BLANK，我不知道是什么问题因为计数是> 0所以理想情况下它应该获取值。
userInfo=mbo.getUserInfo()
POContractNum = mbo.getString("CONTRACTREFNUM")
POContractRevNum = mbo.getInt("CONTRACTREFREV")
POContractOrgID = mbo.getString("ORGID")
PONum = mbo.getString("PONUM")
ContractSet = MXServer.getMXServer().getMboSet("CONTRACT",userInfo)
ContractSet.setWhere("CONTRACTNUM = '" + POContractNum + "' and STATUS= 'APPR' and ORGID = '" + POContractOrgID + "'")
ContractSet.reset()
Contract = ContractSet.getMbo(0)
print 'Contract number', ContractSet.getMbo(0).getString("CONTRACTNUM")
ContractLineSet = MXServer.getMXServer().getMboSet("CONTRACTLINE",userInfo)
ContractLineSet.setWhere("CONTRACTNUM = '" + POContractNum + "' and LINESTATUS = 'APPR' and ORGID = '" + POContractOrgID + "'")
ContractLineSet.reset()
print " Contract Line Where : " + ContractLineSet.getWhere()
print " Contract Lines Selected = " + str(ContractLineSet.count())
print " mbo contract line contract num ", ContractLineSet.getMbo(0).getString("CONTRACTNUM")
++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Contract number PCR1214
Contract Line Where : CONTRACTNUM = 'PCR1214' and LINESTATUS = 'APPR' and ORGID = 'XXXX'
Contract Lines Selected = 1
mbo contract line contract num
