Is there a way to find out how a BPA is created ?

Hello,

As you know a Blanket purchase agreement can be created in the below 3 ways.

a) in buyer work center, key in both header and lines manually for short orders

b) create the header and bulk load the lines in buyer work center.

c) Key in the Purchase order core form.

Any other possible methods, please let me know ?

Now is there a way to find out on which method is used to create particular  BPA ?

Thx,

T.K
