Split Valuation - MIGO error Message No M7043

Hi Gurus,

Client need to maintain Material master for 1 material on different prices and different grades, So I have configured split valuation from customizing.

Created PO for 10 Qty and come to MIGO and distributed 10 qty (5 qty for A Grade and 5 Qty for B Grade) but at the time of saving MIGO, system is showing me Error Valution type A grade differs from Valuation type of Batch B grade.

I haven't maintained any batch for this material.

Appreciate your early response.

Thanks

Shree
