SAP Error Message - Details

• Message type: E = Error

• Message class: B1 - ALE group messages

• Message number: 026

• Message text: Object type & cannot be read for message type & from segment type &

What causes this issue?

A value for object type &v1& was supposed to be read from an IDoc of
message type &v2& - and from a segment of type &v3&.
A reference from this object type to a field in this segment is not
maintained in ALE Customizing.
Object values are read from an IDoc in the ALE layer in the following
cases:
- recipient determination (the configurations here are in the customer
distribution model)
- when linking the IDocs with an application object
- when serializing IDocs in application input
- when using lists for master data distribution

How to fix this error?

In ALE Customizing, check your configurations for the options Master
data distribution->Lists, serializing and linking. Furthermore, check
the configurations in your customer distribution model. If they are
correct, maintain the missing object type in ALE Customizing, or
consult your ALE administrator.
