The Calendar Date Field (CALDT) may be incorrect when directly using the
SASECRSP engine to access the Annual Period Descriptors Time Series
(APERDES) and the Quarterly Period Descriptors Time Series (QPERDES) in
the CRSP/COMPUSTAT Merged Database (CCM).

In order to correctly access APERDES and QPERDES, always store the data
in its own SAS data set by using the SAS DATA Step first. For example,
if you want to perform a PROC PRINT on QPERDES for a specific company,
you would use the following code.  Note: gvkey=6066 identifies a
specific company.

   /* Required. QPERDES data is only accessible as a SAS dataset */

   data qperdes_data;
     set libref.qperdes;
   run;

   /* Avoid using libref.qperdes or libref.aperdes directly */
   /* Use the SAS data set that was created                 */

   proc print data=qperdes_data;
   run;
