PO Release strategy

Hi All ,

We have activated release strategy for PO & Release indicator is maintain as 6 so whenever any changes is done in PO the release startegy is subjected to reset. if value is decreases or increase

Release strategy is configured on following characteristic

1) Order Type 2) Purchase group 3) value

But now Customer requirement is whenever any chages is done in PO besides above characteristic it should go for Rerelease

Kindly suggest

Thanks in advance
