How To Fix DO372 - Referenced class or interface & not active/implemented

SAP Error Message - Details

• Message type: E = Error

• Message class: DO - Dictionary: Mass activation of domains and data elements

• Message number: 372

• Message text: Referenced class or interface & not active/implemented

What causes this issue?

For data elements, structures, tables, and table types you can define
the data type properties in different ways. One option is to set the
type through a <DS:TX.DDDOC_REFTYPE>reference type</> - for example,
reference to a class or an interface.
Alternatively, the data type attributes for a data element can be
defined by specifying a domain or by direct type entry (direct
definition of the data type, number of places and if necessary the
decimal places). You can also define the type of the components of a
structure/table or of the row type of a table type by assigning a
<DS:TX.DDDOC_DDTYP>type</> defined in the Dictionary or with direct
type entry.
You defined a reference to a class/interface that is not active and/or
is not implemented.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

If you want to reference a class/interface, first activate and
implement this class/interface. Then activate it again.
Alternatively you can define the data type attributes in one of the
other ways described above and then activate it again.

• What is the cause and solution for SAP error message DO372 - Referenced class or interface & not active/implemented ?

  The SAP error message DO372 indicates that a referenced class or interface is not active or implemented in the system. This typically occurs in the context of ABAP programming or when working with Business Object (BO) definitions in SAP.
  Cause:
  
  Inactive Class/Interface: The class or interface that is being referenced in your code is not activated. This can happen if the class/interface was recently created or modified and has not been activated yet.
  Missing Implementation: The class or interface may not have been implemented correctly, or the implementation is missing.
  Transport Issues: If the class/interface was transported from another system, it may not have been activated in the target system.
  Namespace Issues: If the class/interface is in a different namespace and not properly referenced, it may lead to this error.
  
  Solution:
  
  
  Activate the Class/Interface:
  
  Go to the ABAP Workbench (Transaction SE80 or SE24).
  Locate the class or interface that is causing the issue.
  Activate it by selecting the class/interface and clicking on the "Activate" button (or pressing Ctrl+F3).
  
  
  
  Check Implementation:
  
  Ensure that the class or interface has the necessary methods implemented.
  If it is an interface, make sure that any implementing classes are also activated.
  
  
  
  Transport Management:
  
  If the class/interface was transported, check the transport logs to ensure that it was successfully imported and activated in the target system.
  
  
  
  Namespace Verification:
  
  Verify that the class/interface is being referenced correctly, especially if it is in a different namespace. Ensure that the correct prefix is used.
  
  
  
  Check Dependencies:
  
  Sometimes, other classes or interfaces that the referenced class depends on may also need to be activated. Check for any dependencies and activate them if necessary.

  Documentation: Review SAP documentation or notes related to the specific class or interface for any known issues or additional troubleshooting steps.
  
  By following these steps, you should be able to resolve the DO372 error and ensure that the referenced class or interface is active and properly implemented.
