Release Strategy - Reset

Dear Team,

My purchase order / PR release strategy should be reset, due to following reasons.

1. Any changes in Item Text / Header Text

2. Any changes in PVC / LD clauses & Base dates

3. Any changes in Retention / Advance %

4. Changes in Delivery Date

Could any one pl suggest on this and how to do it.

Thanks & Regards,

R.Saravanan
