SAP Error Message - Details

• Message type: E = Error

• Message class: C2 - Other messages production orders

• Message number: 226

• Message text: Backflush indicator cannot be set for material &1

What causes this issue?

You have tried to change the backflush indicator for a component with
assigned batch splits (item &V2&, material number &V1&). This change,
however, is not permitted for at least one of these batch splits, for
example, because material has already been withdrawn for this batch
split.

System Response

The backfluch indicator is not changed.

How to fix this error?

Create a new component with the same material number (&V1&) to which
you assign the requirements quantity not yet withdrawn (the
requirements quantity of the batch totals record).
If required, you can also cancel the batch splits for which no goods
withdrawals have yet been posted, or reduce the requirements quantity
of the batch split for which goods withdrawals have already been posted
to the withdrawn quantity.
For this new component, you can make the desired changes to the
backflush indicator and assign batches again.

  The SAP error message C2226, which states "Backflush indicator cannot be set for material &1," typically occurs when there is an attempt to set the backflush indicator for a material that does not meet the necessary criteria. Here’s a breakdown of the cause, potential solutions, and related information:
  Cause:
  
  Material Type Restrictions: The material may be of a type that does not support backflushing. For example, certain material types like non-stock materials or service materials cannot have backflush indicators.
  Configuration Settings: The material may not be configured correctly in the system. This could include missing settings in the material master or in the production configuration.
  Status of the Material: The material might be in a status that does not allow backflushing, such as being marked for deletion or not being active.
  Production Version: If the material is linked to a production version, the production version may not be set up to allow backflushing.
  
  Solution:
  
  Check Material Type: Verify the material type of the material in question. Ensure that it is a type that supports backflushing (e.g., raw materials, semi-finished goods).
  Review Material Master Data: Go to the material master (transaction MM03) and check the relevant views (e.g., Basic Data, MRP, Work Scheduling) to ensure that the backflush indicator is allowed.
  Check Configuration: Review the configuration settings in the system. This may involve checking the settings in the production planning module (transaction SPRO) to ensure that backflushing is enabled for the relevant materials and production processes.
  Production Version: If applicable, check the production version associated with the material. Ensure that it is set up correctly to allow backflushing.
  Consult Documentation: Refer to SAP documentation or help files for specific details on the backflush indicator and its requirements.
