How To Fix MD428 - &1: &2 (S9)

SAP Error Message - Details

• Message type: E = Error

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

• Message number: 428

• Message text: &1: &2 (S9)

¿Qué causa este problema?

The following reasons exist:
Either a component of the planned order or production order entered is
identical to the material that is to be produced on this basis of this
order, or
the low-level code of the component is smaller than the low-level code
of the material produced.
In the first case, recursiveness occurs, in the second case, it is
possible.

Respuesta del sistema

To avoid an endless loop, the dependent requirement is not taken into
account. The receipt elements that cover this dependent requirement are
therefore also not displayed in the order report.

¿Cómo arreglar este error?

Please check the low-level codes of the materials in question.
&ANNOTATION&
