With refeence to thread :
I am also facing a similar situation. However, the amount of data is less than 2000 items (< 2000 records). I am only trying to copy the BP master data and I even tried copying only 10 records. It still gets stuck.
I am using SAP 2005 PL 05, Copy Express: 6.80.01.11
Is it possible to change the Primary key, in this case, change the BP code from the master data and copy the entire record with the new key into the new db?
Any info would be great!
