Transfer Text to Accounting Doc based on Shipping instructions from PO

Hi Folks,

I want to transfer text to accounting document based on purchase order field "Shipping Instructions" ( Item level --> delivery tab).

For e.g. If shipping inst in PO are Road then tranfer TEXT1 to accounting document, if Shipping inst are Rail then transfer TEXT2 to accounting doc. As this is STO scenario accounting doc is generated through replenishment delivery (VL02N) and not through MIGO.

Is there any way to do that?

Regards,

Manmeet
