How To Fix VBDRV015 - At this point, you cannot derive to a by-product

VBDRV015 - Overview

• Message type: E = Error

• Message class: VBDRV - Derivation of Batch Characteristics

• Message number: 015

• Message text: At this point, you cannot derive to a by-product

What causes this issue?

&V1& is a by-product of &V2&. In the <DS:DE.DRVEV>derivation events</>
"Release Process/Production Order" and "Goods Receipt for
Process/Production Order" you cannot derive to a by-product. You can
derive to a co-product at any derivation event.

System Response

You can maintain the condition records, however there is no chance of a
correct derivation, or derivation may only be correct in certain
circumstances.

How to fix this error?

If possible, select a different derivation event if you want to derive
to a by-product.

Procedure for System Administrators

VBDRV015 - Details

• The SAP error message VBDRV015, which states "At this point, you cannot derive to a by-product," typically occurs in the context of production planning and control, particularly when dealing with by-products in the production process. This error indicates that the system is unable to derive a by-product from the main product at the current stage of processing.
  
  Cause:
  
  Incorrect Configuration: The production order or the material master may not be configured correctly to allow for by-products. This could include missing settings in the material master or the production order.
  Production Order Status: The production order may be in a status that does not allow for by-product derivation (e.g., if the order is already completed or technically closed).
  Missing By-Product Definition: The by-product may not be defined in the bill of materials (BOM) or routing for the main product.
  Incorrect Process Flow: The process flow may not be set up to allow for by-products at the
