Global Blanket Purchase Agreement Oracle R12

Next, I try to create a version from the Previous Blanket Purchase order. If I insert the PO ID I received earlier, the system gives me an error (PO_NUM invalid). Both are different types of PO documents (BPA, STANDARD PO). There are no restrictions in creating a standard order for items defined in BPA. Thanks for the information, I would like to get some tips on BPA mass download, do you know any tool or API for me in order to automate the creation/update of BPA? Thank you for your nature and advice….
