MRP create more Schedule Lines than target quantity

Question

We already follow the OSS note 83343, we create a Schedule agreeement and validity date is the same as the Source List and Quota arrangement, also the Target Quanity is the same in the quota arrangement in the maximun quantity and Maximun release qty fields.
After maintaining that data, we run the MRP as follow:
Processing key          NETCH               Net change for total horizon
Create purchase req.    2                   Purchase requisitions in opening period
Delivery schedules      3                   Schedule lines
Create MRP list         1                   MRP list
Planning mode           1                   Adapt planning data (normal mode)
Scheduling              1                   Basic dates will be determined for plann
After that, still in teh schedule agreement was created more schedule lines that the quantoty is bigger that the target quantity in the sched Agreement.
What else we miss??

Answer 1

Thanks for your not help.
That I can investigate is the quota arrenagement is incorrect but for some reason the QA is not working.
