Lot Dates - Based on Date - Expiry Date

 Hi

We are facing a lot of problem with the Lot Based on date and expiry date calculation. The Item - Lot process is been setup as below

Lot Expiration Date Method = 2 (Based on Date)

Lot Process Type = 1 (Lot Assigned Using Date)

Commitment Date method = 1 (Lot Expiration Date)

So when we are doing the Stock Transfer from the Warehouse to a Branch Plant for a lot as below

Lot No                                                  Based on Date                                                Expiration Date                        

2009090100001                                 01/09/10                                                           01/05/11

at the receving time if it is received on 10/09/10

Lot No                                                  Based on Date                                                Expiration Date                        

2009090100001                                 10/09/10                                                           11/05/11

 

our problem is that when we recieve at the Branch plant it should not do any calculation of the Expiration or Based on Date it should be taking the same details. How to do this setup ?
