Hi,
to answer your first question, accrued interest interest to pay (or the Update type 'SE8702') is calculated based on the amount, the coupon rate applicable (in your case 2.1160 if I read it correctly), the period between the last coupon payment date (in your case 15.09.2014) and the current bond purchase date (in your case 16.11.2014) and finally the number of days in a year (depending on the interest rate method applicable).
regarding the second question - I would guess interest deduction inc. reclaim tax or the Update type 'SE3006' is generated as a result of the Flow type '0306' and as the Flow category is 'Other Flow/ Condition', it is just entered manually.
hope this will help you.
Kind regards,
Renatas
