Same delivery Date in Schedule lines

Hi,

We have the following master data settings:-

MRP Type- VB

Re Order Point- 100

Lot Size- HB - Replenishment to max stock

Max Lot Size- 20

Maximum Stock Level- 150

Planned Delivery Time- 5 days

GR processing time-1day

Planning run on 05.11.2015

System generated the eight schedule lines as below:-

11.11.15     20

11.11.15     20

11.11.15     20

11.11.15     20

11.11.15     20

11.11.15     20

11.11.15     20

11.11.15     10

Why the delivery date is same for all the schedule lines. My client wants it should be different as per planned delivery time.

How to achieve this.

Regards

Aman
