How To Fix SPRX103 - Object used by an interface from another namespace

SPRX103 - Overview

• Message type: E = Error

• Message class: SPRX - Proxy Generation

• Message number: 103

• Message text: Object used by an interface from another namespace

In the Integration Builder, when defining an interface in namespace
"A", it is possible to also use messages from another namespace "B".
However, because this message is assembled from type definitions from
namespace "B", the interface from namespace "A" indirectly uses a large
number of type definitions from namespace "B".
If a proxy is now generated for this interface from namespace "A", then
the proxy types for the message and type definitions must be generated
from namespace "B".
Since it cannot be ensured that the namespaces "A" and "B" generate
their proxies in the same system, a new proxy type is generated in this
case.
Therefore, namespace "A" has its own proxies for the message and the
type definitions from namespace "B". This ensures that namespaces "A"
and "B" are independent of each other.
This independence is particulary important if messages or type
definitions are to be developed further in namespace "B". This further
development should not change interface definitions in namespace "A".

SPRX103 - Details

• The SAP error message SPRX103 indicates that there is an issue with an object being used by an interface from a different namespace. This typically occurs in the context of ABAP development, particularly when dealing with interfaces, classes, or other objects that are defined in different namespaces.
  
  Cause:
  The error arises when:
  
  An object (like a class, interface, or method) is being referenced or used in a way that violates the namespace rules defined in the SAP system.
  The object being referenced is not accessible due to namespace restrictions, which are designed to prevent conflicts between different development objects.
  
  
  Solution:
  To resolve the SPRX103 error, you can take the following steps:
  
  
  Check Namespace Configuration:
  
  Ensure that the namespaces are correctly configured in your SAP system. Each development object should be in its appropriate namespace.
  
  
  
  Review Object References:
  
  Identify the object that is causing the issue. Check the code where the error occurs and see if it is trying to access
