• What is the cause and solution for SAP error message WZRE_PRX209 - Only one Identification Scheme can be the default one. ?

  Certainly! Here's a detailed explanation for the SAP error message:
  
  SAP Error Message:
  WZRE_PRX209 Only one Identification Scheme can be the default one.
  
  Cause:
  This error occurs when you try to set more than one Identification Scheme as the default in SAP. Identification Schemes are used in various SAP modules (e.g., SAP Master Data Governance, SAP MDG, or SAP CRM) to uniquely identify business partners, materials, or other entities. The system requires that only one Identification Scheme is marked as the default to avoid ambiguity during data processing or identification.
  If multiple Identification Schemes are flagged as default, the system cannot determine which scheme to prioritize, hence it throws this error.
  
  Solution:
  
  
  Check Identification Schemes Configuration:
  
  Go to the configuration or customizing transaction where Identification Schemes are maintained (this could be in IMG under the relevant module, or in the MDG configuration).
  
  
  Identify Default Flags:
  
  Look for all Identification Schemes and check which ones are marked as default.
  
  
  Set Only One Default:
  
  Ensure that only one Identification Scheme has the "Default" flag set. Remove the default flag from all others.
  
  
  Save and Test:
  
  After correcting the default flag, save the configuration and test the process again.

  Transactions/Paths:  
  
  In SAP MDG, Identification Schemes can be maintained via customizing under:
  
  SPRO -> SAP NetWeaver -> General Settings -> Identification Schemes  
  Or via specific MDG configuration UIs.
  
  
  
  Why Only One Default?
  
  The default Identification Scheme is used by the system as the primary method for identifying records during data replication, matching, or validation processes.
  
  
  Impact of Multiple Defaults:
  
  Having multiple defaults can cause data inconsistencies, errors in data matching, or failures in data replication.
  
  
  Additional Checks:
  
  If you are working with custom Identification Schemes or have recently imported configuration, verify that the import did not accidentally set multiple defaults.
  
  
  
  If you provide the exact module or context (e.g., MDG Business Partner, Material Master, CRM), I can give more precise navigation or steps.
  
  Summary:
  
  The error WZRE_PRX209 means you have more than one Identification Scheme marked as default. Fix it by ensuring only one Identification Scheme is set as default in the configuration.
