How To Fix B1008 - Mandatory segment & in message type & cannot be filtered

SAP Error Message - Details

• Message type: E = Error

• Message class: B1 - ALE group messages

• Message number: 008

• Message text: Mandatory segment & in message type & cannot be filtered

What causes this issue?

During segment filtering in the ALE layer, a segment of type &v1& was
supposed to be filtered from an IDoc with message type &v2&. However,
this is not possible as the segment is marked as mandatory in the IDoc
type. Mandatory segments contain essential IDoc information and cannot
be left out.

How to fix this error?

Check the configurations for the segment filter in ALE Customizing, or
use transaction WE30 to check the definition of the IDoc type.
