Country of origin in MIGO

Hi All,

I am having a situation where my vendor is in China and I raise him a PO but he is having one plant in China and other in Taiwan and he further based on his availability pass the order further.

Now some time instead of china some time Taiwan plant supply me the material.

Now I want to capture the Country of origin Info at the time of GR(MIGO) So do u have any Idea how to add Country of origin field in MIGO or do u have better advise to me to overcome my above issue.

Thanks,

Lekhram
