SNP Heuristic run Planned order date at begining, middle or end of month bucket

Hi,

I have a requirement like, when SNP Location Heuristic run execute SNP planned orders are creating always end of the month. I need planned order to be created by heuristics at start of month or middle of month.

Example:

Planned independent Req - Date: 01.10.2014 - 2000 KG

                                                 06.10.2014 - 1500 KG

                                                 15.10.2014 - 5000 KG

                                                 20.10.2014 - 2800 KG

                                                 28.10.2014 - 3000 KG

SNP Planned order- Date:          31.10.2014 - 2000 KG

                                                31.10.2014 - 1500 KG

                                                31.10.2014 - 5000 KG

                                                31.10.2014 - 2800 KG

                                                31.10.2014 - 3000 KG
