Change Dates in Release Process Order

Hi All

Need your suggestion in below scenario.

I want to change the dates in released process order.Will explain you reason behind this.

1.Process order is created.It has subcontracting process defined in controll key.

2.After release the process order.Subcontracting Purchase requisition is created.Aginst that we issue material to vendor for further

processing.

3.After issueing raw material.We will have a negotiation with supplier.So that he can deliver early.Suppose planned delivery duration is 10 days.After negotiation Supplier will take 5 days deliver.

4.Due to this change.My production schdule dates are changed.I dont want to do the Read PP Master Data.Since I am using the Auto batch determination.It will impact the batches assigned to components.

5.Since we are using APO.It is impacting APO planning.Availablity date gets changed.If supplier delivers the goods earlier.

Any suggestions this issue.
