Question on request date populated by R34650

Hi

We are working in E9.0 and need quick info on how request date is populated when we run R34650. Have extracted the sales history using R3465 and it has populated AA records in  F3460 table with request date, in alignment with fiscal date period defined in P0008B.  Then we use AA to forecast the records for future using R34650. The same fiscal date pattern is used in PO of R34650. After running R34650, F3460 is populated with request date as future. Any idea how the request date is calculated when we run R34650 ?.

This is the scenario: In P0008B, weekly bucket # 40 is populated with date as 10/02/2015 for year 2015 and for year 2016 as 09/30/2016. Run R3465 and it populates AA qty as 150 with request date as 10/02/2015. Then run R34650 with forecast method "1" with 110 %. and it populates F3460 with BF type records. My understanding is that R34650 populates BF records with forecast qty as 165 and request date as bucket # 40 (09/30/2016). Is that correct ?. Appreciate your inputs.
