  The SAP error message R1756 "Define &1 (&2) uniquely" typically occurs when there is a conflict or ambiguity in the configuration of certain elements within the SAP system. This error is often related to the definition of master data or configuration settings that need to be unique but are currently defined in a way that allows for multiple entries.
  Cause:
  
  Duplicate Entries: The most common cause of this error is that there are multiple entries for the same key in the configuration or master data tables. For example, if you are trying to define a material, vendor, or customer, and there are already existing entries that match the criteria, the system will throw this error.

  Solution:
  
  Check for Duplicates: Review the entries in the relevant master data or configuration tables to identify any duplicates. You can use transaction codes like SE16 or SE11 to view the data in the relevant tables.

  Review Configuration Settings: Go through the configuration settings related to the specific area (like material management, vendor management, etc.) to ensure that they are set up correctly and uniquely.
  Use Unique Identifiers: Ensure that you are using unique identifiers for the entries you are trying to create or modify. This may involve adjusting the key fields or combinations of fields that define uniqueness.
  Consult Documentation: Refer to SAP documentation or help resources for specific guidance on the area you are working with, as the exact steps may vary depending on the module and context.
