inventory closing --> minimum settle quantity percent --> how axapta is calculaiting this

Hi,

I use weighet average. Minimum settle quantity percent is set up on 2,5%. I closed inventory. After that I check settlements. I choose one of trasactions that is intersting me and this is what I get:

Settled quantity Amount settled
2672,5375 300318,92
787,5525 88875,3
872,3498 98444,68
871,1356 98307,65
877,1022 98980,99
879,4973 99251,27
879,3424 99233,79
883,6007 99714,34
879,6564 99269,23
881,101 99432,25
881,2936 99453,98
879,4219 99242,76
878,5552 99144,95
880,6823 99384,99
876,516 98914,84
876,3695 98898,3
871,5333 98352,54
868,8661 98051,54
10,74 1212
11,64 1313,58
19,37 2185,91
870,6708 116774,36
871,0309 116822,66
873,5432 117159,61
870,0678 116693,5
872,4043 117006,86
879,5266 117962,11
875,6242 117438,72
879,3591 117939,65
879,8658 118007,59
879,1414 117910,44
880,4478 118085,66
879,4261 117948,63
874,4685 117283,72
866,4083 116202,68
874,3345 117265,75
836,9175 112247,38
-31502,1 -3850733,13

This transaction is sales order for 31502,1 pcs. I undestand that minimum settle quantity 31502.1 x 2,5%=787,55. My question is why axapta takes more than minimum? From where axapta get first value ( 2672,5375 )? Minimum is 787,55 why system took more? In other words how axapta is calculaiting this?

thx for help!
