Cross Apply - DateRollup With Acceptable Gap

Hi,

I am pulling  data  From OLEDB Source

MemID      Indicator     EffectDate      EndDate
1                 y              20100401      20100801
1                 y              20110129       20120506
2                 y             20100606        20111231
2                 y             20120101        20120601

If the MemID  is same  and Indicator is same then it should look for dates .

See the MemID 2 ,  Enddate is 20111231 AND again  started in 20120101 SO there in no gap in  ENDDATE AND  EFFECTDATE
Then the record Detination should come LIKE   

• MemID      RiskInd     EffectDate      EndDate
  1                 y              20100401      20100801
  1                 y              20110129       20120506
  2                  y              20100606       20120601

I should do this in ssis , Between Source and Destination components

Thanks,
