Dear SAP Experts,
I meet the error message number: ME062 when creating Purchase Order.
![2015-11-16 11-15-54.png]()
I searched the relevant solution from SCN and Notes, they always said the root cause is about Quantity/value updating of material type(T-code: OMS2), but the configuration is no problem(please see the screenshot for details), and I just copied the material number from a normal material, and I just changed the valuation class, this is the only difference compare with the normal material.

Could you please tell me whether there's any relationship with valuation class for the error message: ME062? Because If I change the valuation class from 0001 to C394, I can create the PO without any error message. So I make the same configurations in T-code: OBYC for the new valuation class:0001 according to the normal valuation class: C394 . But the error is still appeared when creating PO with valuation class:0001, it's very strange, please give me some advises, thanks in advance.

Steps for Reconstruction
1. Create new Valuation Class matching the normal Account category reference(T-code:OMSK);
2. Create new material number by copying normal material number(T-code: MM01); Only change to new valuation class.
3. Create PO with the new material number(T-code: ME21N).
