How To Fix KX910 - Field name & already exists -> Choose another name

SAP Error Message - Details

• Message type: E = Error

• Message class: KX - EC-EIS/EC-BP: Data basis, data collection

• Message number: 910

• Message text: Field name & already exists -> Choose another name

What causes this issue?

Field name &v1& of the sender structure from an ABAP query is already
used by another field in the same sender structure. In order to
transfer the chosen data from the ABAP query to SAP-EIS, the system
requires the unique assignment of all fields of the sender structure
(-> internal table "%LDESC", field "FNAME") to the fields of the
receiver structure (SAP-EIS).

System Response

Since the field names of the receiver structure in SAP-EIS are shorter
than those of the sender structure, a shorter field name must be
chosen. This occasionally means that similar fields with the same names
already exist in the sender structure.
The system requires you to create a unique name of the field in the
sender structure (-> SAP-EIS table T242S, T241S, (T242D), field
"SFELD").

How to fix this error?

Make sure that you enter a unique field name which, if possible, also
indicates the contents, for the field in the sender structure.

  The SAP error message KX910, which states "Field name & already exists -> Choose another name," typically occurs when you are trying to create or modify a field in a data structure, table, or report, and the name you are attempting to use is already in use within the same context. This can happen in various SAP modules, including ABAP programming, data dictionary definitions, or customizing settings.
  Cause:
  
  Duplicate Field Name: The most common cause is that the field name you are trying to create already exists in the same context (e.g., in the same table, structure, or report).
  Namespace Conflicts: If you are working in a development environment, there may be conflicts with existing objects in the same namespace.

  Solution:
  
  Choose a Unique Name: The simplest solution is to choose a different name for the field that does not conflict with existing names. Ensure that the new name adheres to SAP naming conventions.
  Check Existing Fields: Use transaction codes like SE11 (Data Dictionary) or SE80 (Object Navigator) to check for existing fields in the relevant tables or structures.
  Namespace Management: If you are in a development environment, ensure that you are using the correct namespace for your custom objects to avoid conflicts with standard SAP objects.
  Review Transport Requests: If the issue arises during a transport, check the transport requests to ensure that there are no conflicts with existing objects in the target system.
  Consult Documentation: If you are unsure about naming conventions or existing fields, refer to SAP documentation or consult with your SAP Basis or development team.
  
  Related Information:
  
  SAP Naming Conventions: Familiarize yourself with SAP's naming conventions for fields, tables, and other objects to avoid conflicts.
  Transaction Codes: Use SE11 for Data Dictionary, SE80 for Object Navigator, and SE37 for function modules to explore existing objects.
