SAP-MM CO rouding issues

Hi, we encounter a strange case :

it can be resumed by the attached screenshot

sans-titre.png

we make a 101 via purchase order : value rounded is 15.01

we make two identical 601 (via sales order)

both 601 are valuated at 7.51 : resulting in a null stock with negative value

We know how to correct that, but we want to know how it happens (afeter that, no 101 are possible, with message M7308, until you bring back the stock valuation to 0 by CO manipulations)

We observed that in some cases, SAP rounds the issues accordingly to come back to a zero stock

price control is standard

Any ideas ?

At least pointing me to the right documentation ?

We are convinced acustomizing exists for those roudings, but can't find it.

    Do you use shared_mbew function then check this note 924164.

    The total in a MB51 list is not much worth, as MB51 just has material documents while moving average prices are influenced by accounting documents, e.g. when you receive an invoice with a different value or when you do a price change in MR21 then you have no material documents for these events, still the MAP changes and the total in MB51 shows a difference.

    The question is whether your valuation in the material master really went negative, has 0 quantity and -0.01 value
