CASE语句中的错误

编写CASE语句时出现问题。请帮助CASE语句中的错误

insert into CDR(rts,smscid,count,statusflag,operator,identifier) 
    select trunc(rts),smscid,statusflag,operator, 
    (case when smscid='BPL-MUM' and operator='BPL' and is_number(replace(replace(replace(senderid, 'DM-',''), 'LM-',''),'BT-',''))=0 THEN "LOOP TRANSACTIONAL" 
      when smscid='BPL-MUM' and operator!='BPL' and is_number(replace(replace(replace(senderid, 'DM-',''), 'LM-',''),'BT-',''))=0 THEN "NONLOOP TRANSACTIONAL" 
      When Smscid='BPL-MUM' And Operator='BPL' And Is_Number(Replace(Replace(Replace(Senderid, 'DM-',''), 'LM-',''),'BT-',''))!=0 THEN "LOOP PROMOTIONAL" 
      when smscid='BPL-MUM' and operator!='BPL' and is_number(replace(replace(replace(senderid, 'DM-',''), 'LM-',''),'BT-',''))!=0 THEN "NONLOOP PROMOTIONAL" 
      END),sum(count)  
     From Mis_Summary_Dn Where Rts Between '26-dec-2012' And '27-dec-2012' And Statusflag='SUCCESS' Group By Trunc(Rts),Smscid,Statusflag,Operator;

我收到错误，如

SQL Error: ORA-00904: "NONLOOP PROMOTIONAL": invalid identifier 
00904. 00000 - "%s: invalid identifier" 
*Cause:  
*Action:

把你的字符串单引号，不是双引号。双引号是标识符

'NONLOOP PROMOTIONAL'
