Purchase order - two batches of the same product. Not allowed

Hi all,

I have the following problem - I am trying to enter a Purchase order with stock of the same product in two batches, with two different batch numbers. But when I try to save I see message “Same item cannot be entered multiple times.” Does anyone know a workaround other than entering a separate invoice for the duplicate products with different batch numbers?
Thanks

There is not batch selection for item in purchase order form.

Batch selection have to be done in Purchase receipt or Material Receipt.

I tried purchase receipt with same item in item table in row 1 and row 2 and each have different batch and i was able to save and submit it.
