Moving average price for material is negative - MIRO

Hi Experts,

This is very common error and I found lots of threads for the same. But here the case is a bit different.

Normally, we get this error when we are trying to post the invoice with value greater than 'Total value' (MBEW-SALK3). Am I right?

But here, we are trying to post the invoice with amount less than 'Total value' (MBEW-SALK3).

Scenario-

PO qty            - 2 PC, 

Net Amount     - 18.58 USD / PC

GR done         - 2 PC with amount 37.16 USD ( 231.38 RMB because currency in material master is RMB )

Material master accounting view

We are trying to post the invoice for 1 PC with value 18.58 USD but it is showing error as MAP for material XXX is negative.

Any input will be highly appreciated.

Thanks,

Rudresh
