  Check Existing Declarations: Use the SAP transaction SE80 (Object Navigator) or SE11 (Data Dictionary) to search for existing global variables. This can help you identify where the name is already in use.
  Use a Prefix: If you are working in a team, consider using a prefix that identifies your module or your name to reduce the likelihood of naming conflicts.
  Review Global Declarations: If you are working with includes or function groups, review all global declarations to ensure that there are no conflicts.
  
  Related Information:
  
  Naming Conventions: It's a good practice to follow naming conventions that include prefixes or suffixes to avoid conflicts. For example, using a project-specific prefix can help distinguish your variables.
  Documentation: Maintain documentation of global variables used in your projects to avoid future conflicts.
  Code Review: Implement a code review process where team members can check for naming conflicts before code is moved to production.
