The thing is that the number for each sample for each month will not be the same. For example, For 201301, then sample size may be 23, for 2011302 may be 35, etc. However, the monthly sample size will be predetermined and known. Is it possible to generate random numbers for each&nbsp; month separately and then select the required number of Sales Amounts for each month. Thanks.</P> Sun, 24 Jan 2016 02:51:55 GMT https://communities.sas.com/t5/SAS-Programming/re-Data-Selection/m-p/245670#M45873 twildone 2016-01-24T02:51:55Z https://communities.sas.com/t5/SAS-Programming/re-Data-Selection/m-p/245671#M45874 <P>Use <STRONG>proc surveyselect</STRONG> with months as your strata and specify <STRONG>ALLOC=SAS_dataset</STRONG> to give the allocation for each stratum (month).</P> Sun, 24 Jan 2016 03:46:03 GMT https://communities.sas.com/t5/SAS-Programming/re-Data-Selection/m-p/245671#M45874 PGStats 2016-01-24T03:46:03Z
