Deriving quarter from date field in Oracle

Hi,

I have a date field in query in Oracle and I am having trouble pulling out the quarter.  Here is the code:

Select --URA_DOC_ITEM.prod_num,
--URA_PROD.SKU, 
URA_DOC_ITEM.CAT_OBJ_NAME, URA_DOC_ITEM.PROD_GRP_ID,
URA_DOC_ITEM.member_id_updated, URA_DOC_ITEM.date_updated,
  fn.FLD_VALUE,
  fd.FLD_VALUE,
    URA_DOC.STRUCT_DOC_TYPE DOC_TYPE,
 MAX(trunc(URA_DOC_ITEM.start_date)) STARTDT,  

  MAX(URA_DOC_ITEM.BASE_PRICE) URA,
 max( amp.BASE_PRICE) as amp,
 max( bp.BASE_PRICE) as BP,
 max( amp.BASE_PRICE)  - max( bp.BASE_PRICE) as CALCURA--,
 --max( amp.BASE_PRICE)  - max( bp.BASE_PRICE)/ CWAC.base_price as DISC

 
 
from    mmasw_cnt.MN_STRUCTURED_DOC URA_DOC,
        mmasw_cnt.MN_STRUCT_LINE_ITEM URA_DOC_ITEM,
         MMASW_PRD.MN_ITEM URA_PROD,
	  mmasw_prd.mn_Cat_Map m

Select allOpen in new window

I'd like to represent the line
MAX(trunc(URA_DOC_ITEM.start_date)) STARTDT   as YYYYQ, but I cannot get it to work without an error.

I have used EXTRACT and TRUNC but to no avail. Any ideas?
