POP Receipt Transaction - Fill the lines with other receipts..

Hi, i have a problem with the pop receipt windows and the "View -> Vendor Items" button in only one of the companies of the installation, when i press that button, instead of showing only the vendor items, it fills the receipt with lines of other receipts and if i manually edit the cost of the line, it edits the original receipt....

In other companies of the same instance works good.

Gp Version : 12.00.1745 (R2)

Its the Spanish Version.

I open the POP Recepit Windows:

1.Select Ship/Invoice

2.Select Vendor

Then i go to "View -> Show Vendor Item"

GP prompt me to "Save / Delete / Cancel "

(I select Delete)

And then fills my receipt with lines of other receipts... I can modify the lines and the canges are applied to the original receipts.

I dont know what to do...
