BRAIN_DEV700 - Duplicate technical name (mapname) &1 exists in &2 and &3.

SAP Error Message - Details

• Message type: E = Error

• Message class: BRAIN_DEV - BRAIN messages (for use by development)

• Message number: 700

• Message text: Duplicate technical name (mapname) &1 exists in &2 and &3.

What causes this issue?

Several structure elements or cells in the query have the identical
technical name (mapname). The technical name can be used to address
structure members in SAP Analysis for Microsoft Office with the Excel
function SAPGetData.
If a selection only consists of a reusable key figure (calculated key
figure or restricted key figure), the system automatically derives the
technical name for the selection from the key figure if there are no
further filters in this selection.

System Response

The query can be generated and executed. If the Excel function
SAPGetData is used in SAP Analysis for Microsoft Office, it is not clear
which structure member is addressed.

How to fix this error?

You can ignore the warning if you do not plan to use SAP Analysis for
Microsoft Office in the manner described. Otherwise<(>,<)> choose
different technical names for the structure members mentioned. Maybe you
even have to explicitly specify a technical name if the technical name
has previously been derived from the underlying key figure.

Procedure for System Administrators

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

• What is the cause and solution for SAP error message BRAIN_DEV700 - Duplicate technical name (mapname) &1 exists in &2 and &3. ?

  The SAP error message BRAIN_DEV700 indicates that there is a duplicate technical name for a mapping object (mapname) in the system. This typically occurs in the context of SAP BW (Business Warehouse) or SAP HANA when you are trying to create or modify a mapping object, and the system detects that the name you are trying to use already exists in the specified objects.
  Cause:
  
  Duplicate Naming: The most common cause is that you are trying to create a new mapping object (like a transformation, data source, or InfoObject) with a name that already exists in the specified repository or namespace.
  Transport Issues: Sometimes, if you are working with transports, the same object might have been transported multiple times, leading to duplicates.
  Development Environment: If multiple developers are working in the same development environment, they might inadvertently create objects with the same name.
  
  Solution:
  
  
  Check Existing Objects: 
  
  Use transaction codes like SE11 (Data Dictionary), SE80 (Object Navigator), or RSA1 (Data Warehousing Workbench) to search for the existing object with the same name.
  Identify the existing objects in the specified repositories (&2 and &3 in the error message).
  
  
  
  Rename the New Object: 
  
  If you find that the name is indeed taken, consider renaming your new mapping object to something unique.
  
  
  
  Delete or Modify Existing Object: 
  
  If the existing object is no longer needed, you can delete it or modify it to avoid the conflict. Be cautious with this approach, especially in production environments.
  
  
  
  Namespace Management: 
  
  If you are working in a shared environment, consider implementing a naming convention or using namespaces to avoid such conflicts in the future.
  
  
  
  Transport Management: 
  
  If the issue is related to transports, ensure that you are managing your transports properly and that objects are not being duplicated across different systems.
  
  
  
  Related Information:
  
  Transaction Codes: Familiarize yourself with relevant transaction codes such as SE11, SE80, RSA1, and SE37 (for function modules) to navigate and manage objects effectively.
  SAP Notes: Check SAP Notes for any known issues or patches related to this error message.
  Documentation: Review SAP documentation on naming conventions and object management in BW or HANA to prevent future occurrences.
  
  By following these steps, you should be able to resolve the BRAIN_DEV700 error and prevent it from happening again in the future.
