Probme when I copy a Purchase order with advansed price.

I have  a problem when I copy a Purchase order with advansed price.

The system copies all, but it makes an error when it copies the price history.

For example this is  the F4074’s rows of my purchase order:

ALOSEQ               ALAST

10                           PREZZO

20                           SCONTO1

30                           SCONTO2

40                           SCONTO3

 

If I copy it, when I press the button of price history I have this:

SeqNr   AST

10           SCONTO3

20           SCONTO1

30           SCONTO2

40           SCONTO3

 

The system doesn’t copy the first line with ALAST = ‘PREZZO’ (from original order), but I have twice the line with ALAST = ‘SCONTO3’.

Can you help me?

Thanks
