Hola! por si es de ayuda.. o mas que nada de confirmacíon,hace unos dias informamos en el oss de sap esto como un error y me confirman que la nota 204252 es correcta y no existe solución para este problema.
Esta es la respueta:
I can only confirm the information that you have already found in the
note 204252.
When the Purchase Order items have been assigned to more than one
account (this is, when they use multiple account assignment), instead
of valuation being carried out at the time of the goods receipt, the
relevant materials are not valuated until the invoice data is entered
into the system.
That is the reason why when you create a Purchase Order with Multiple
Account assignment, the system automatically sets the goods into
non-valuated (if you remove this flag under the 'Delivery' tab of ME21N,you get the warning message 'Goods receipt posted unvaluated due to
multiple account assignment' - Message no. MEPO039 -).
Therefore, you have to wait until the invoice data is entered. There youcan set your proposals.
Please also see the F1-Help for the 'GR Non-Valuated' Field (EKPO-WEUNB)the Help Text states the following:
"Goods receipt, non-valuated:
Specifies that the goods receipt for this item is not to be valuated.
Use:
Set the indicator if goods receipts involving this material are not to
be valuated. The valuation of the purchase order item will then take
place at the time of invoice verification.
This indicator must be set in the case of multiple account assignment
for example.
Note:
If the indicator has been set for an item with the material type
non-valuated, the quantity recorded in Inventory Management can
differ from the value in Financial Accounting during the period between
goods receipt and invoice receipt, since the value is not updated until
the invoice is posted in Financial Accounting."
Please, see also the attached notes:

204252 - Valuated goods receipt for multiple account assignment.
About the way the system works when dealing with service items, this is
indeed different.
The case how multiple account assignments are handled in services are
different from that of the materials.
As mentioned previously, in case of materials, if there is multiple
account assignment then the system will post a Goods receipt with value
zero. The system defaults the flag to obtain this valuation.
For services, the service items are maintained at one level deeper than
materials. This means that we can have multiple service lines for a
single service line item (item category D).
Each of these individual service lines can have its own account
assignment which can be single or multiple, and even if all service
lines have multiple account assignment, then also a goods receipt
can be posted with value in case of services. This is the reason why
the system does not default the GR-Non Valuated flag as in the case of
materials.
About the possibility to dis-allow the use of Multiple Account
Assignment in ME21N, this is not available: In OME9 you can set the
default value for the relevant account assignment category. For example,for the account assignment category K you can decide with the indicator
'ID: AcctAssgt Scrn' whether you want:
1 Single account assignment
2 Multiple account assignment
but this is only a default value. The user will still be able to change
this defaulted value into a different one.
