gray out the address fields after save the opportunity

Hi All,

I am facing one issue after saving the  opportunity  transaction.

After saving the opportunity transaction , When I open the parties Involved with Edit button to change the address of the partner, then first time address fields are coming in gray out mode. When I open the second time the same partner , then address fields are coming in change mode .

This is happening after executing the ORDER_SAVE badi implementation . I don't have much code in Implementation .

Even I place the ABAP statement CLEAR in BADI implementation, the issue is occurring .

is it issue with BOL buffer ? or any other?

regards,

rama
