How To Fix MD434 - &1: &2 (S5)

SAP Error Message - Details

• Message type: E = Error

• Message class: MD - Material Requirements Planning (MRP)

• Message number: 434

• Message text: &1: &2 (S5)

What causes this issue?

No configuration valuation (characteristic valuation) could be
determined for the order.
However, the bill of material is configurable and can only be exploded
when a configuration valuation is available.
As the configuration valuation is missing, the bill of material has not
been exploded.
Possible causes of error:
For make-to-order production, the configuration valuation is
transferred from the requirement. The cause of error is probably that
the requirement does not have a configuration valuation.
For make-to-stock production, the configuration valuation is
transferred from the material master. There is probably no
plant-dependent characteristic valuation (variant) in the material
master.
For planning with a "Planning without final assembly" strategy, the
configuration valuation is transferred from the independent requirement
or from the material master (variants or indicator planning variant).
A configuration valuation may not have been defined in the independent
requirement or the material master.

System Response

This exception message is only shown in the MRP list. In the stock/
requirements list, the more general exception message 52 "No BOM
selected" is displayed.

How to fix this error?

Check whether the configuration valuation is missing in the requirement
or the material master.
