CK727 -Lot size cannot be passed on in combination with mixed costing

Question

I get below error.
We have KMAT materials and scenario  is Non Valuated Sales Order Stock.
in our PPC4 - we have below settings. (Both are SAP recommended)
Qty Structure tab we have Pass on Lot size "1" with individual requirements (must of Non Valuated Sales) and
Transfer Control "PC03" has "Current Std Cost" with "Transfer only with Collective requirements"
I just created a mixed cost qty structure. In it I even added Costing type "01". Sales order costing type is "18".
Mixed costing works as expected. However we are unable to create any Sales Orders.
Lot size cannot be passed on in combination with mixed costing
Message no. CK727
Diagnosis
For costing variant PPC4 and costing version 01, it was defined in Customizing that a mixed cost estimate should be created for quantity structure category M0001. At the same time, it was defined in the costing variant that the Pass_on_lot_size function should be active.
System Response
Mixed costing cannot be carried out simultaneously with Pass on lot size . Costing cannot be proceeded with.
Any help is appreciated.

Answer 1

Hi Kala,
system's response is correct
In the standard program the combination of mixed costing and
simultaneously pass on lot size is not possible.
Please review SAP Notes 402440, 584420 and 749128 .
In particular the SAP Note 402440 describes the determination of the
costing lot size at a mixed costing in detail.
