SAP Error Message - Details

• Message type: E = Error

• Message class: CFD_ABAP_MANAGED_FLD - Custom Fields: Messages of ABAP-Managed Fields

• Message number: 058

• Message text: Another field with the same name &1 is also used in include &2&3&4.

What causes this issue?

The field <(>&<)>1 is used in at least the following includes <(>&<)>2
<(>&<)>3<(>&<)>4. Each of these includes correspond to a business
context. SAP may include different persistence includes to the same
structure in a later release. Therefore, all fields of a business
context must be unique to prevent name clashes, and it is not allowed to
reuse the field names in other business contexts.
If you decide to ignore this advice, a later upgrade might be stopped in
the shadow phase during dictionary activation.

How to fix this error?

Decide which field is required in which business context.
If more than one of your existing fields, with the same name, shall be
added to different business contexts, you need to perform a migration.

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

Migration:
Scenario 1: Database fields represent logically the same field in
different business contexts
1.) Create a new field with a unique name and add it via append to the
desired business context
2.) Enable your existing field via transaction <AB>scfd_eui </>as custom
field
3.) Transport your development to subsequent systems
4.) Perform a data migration
5.) Make sure your old field is not used any more
6.) Delete your old field and transport the changes.
Scenario 2: Database fields are independent of each other
1.) Create a new custom field via Fiori app "Custom Fields and Logic"
2.) Transport your development to subsequent systems
3.) Perform a data migration
4.) Make sure your old field is not used any more
5.) Delete your old field and transport the changes.

• What is the cause and solution for SAP error message CFD_ABAP_MANAGED_FLD058 - Another field with the same name &1 is also used in include &2&3&4. ?

  The SAP error message CFD_ABAP_MANAGED_FLD058 indicates that there is a naming conflict in your ABAP code. Specifically, it means that there are multiple fields with the same name defined in the same context, which can lead to ambiguity and confusion in the program.
  Cause:
  This error typically occurs when:
  
  You have defined a field with a specific name in an ABAP program or include, and then you attempt to define another field with the same name in the same program or include.
  The field name is not unique within the scope of the program or include, leading to a conflict.
  
  Solution:
  To resolve this error, you can take the following steps:
  
  
  Identify the Conflicting Fields: Check the error message details to identify the field name (&1) and the includes or programs (&2, &3, &4) where the conflict occurs.
  
  
  Rename the Fields: If possible, rename one of the conflicting fields to ensure that each field has a unique name within the same scope. This is the most straightforward solution.
  
  
  Check Includes: If the fields are defined in different includes, ensure that the includes are not being used in a way that causes the fields to be treated as part of the same scope.
  
  
  Review Data Dictionary Objects: If the fields are part of data dictionary objects (like structures or tables), ensure that they do not have the same name in the same context.
  
  
  Use Unique Naming Conventions: Implement a naming convention that helps avoid such conflicts in the future. For example, prefixing field names with a module or function-specific identifier can help maintain uniqueness.
  
  
  Check for Inheritance: If you are using inheritance in your classes, ensure that the fields are not being inherited in a way that causes naming conflicts.
  
  
  Related Information:
  
  ABAP Naming Conventions: Familiarize yourself with best practices for naming variables and fields in ABAP to avoid conflicts.
  Debugging Tools: Use the ABAP debugger or the code inspector to analyze your code for potential naming conflicts.
  Documentation: Refer to SAP documentation or community forums for additional insights and examples related to this error.
  
  By following these steps, you should be able to resolve the CFD_ABAP_MANAGED_FLD058 error and prevent similar issues in the future.
