conversion. If not the mapping needs to be changed.
You cannot run the transformation solution because certain prerequisites

• What is the cause and solution for SAP error message CNV_20310_CHECK035 - Differences regarding currency keys detected, merge not possible ?

  The SAP error message CNV_20310_CHECK035 indicates that there are differences in currency keys detected during a data migration or conversion process, which prevents the merging of data. This error typically arises in the context of SAP's data migration tools, such as the SAP S/4HANA Migration Cockpit or other conversion tools.
  Cause:
  The error occurs when the system identifies that there are inconsistencies in the currency keys used in the data being processed. This can happen due to several reasons:
  
  Different Currency Keys: The source data may contain different currency keys that are not compatible with each other.
  Missing Currency Configuration: The target system may not have the necessary currency configuration set up to accommodate the currencies present in the source data.
  Data Mapping Issues: There may be issues in the mapping of currency fields between the source and target systems.
  
  Solution:
  To resolve the CNV_20310_CHECK035 error, you can follow these steps:
  
  
  Check Currency Configuration:
  
  Ensure that all currencies used in the source data are defined in the target system. You can do this by checking the currency settings in the SAP configuration (transaction code OB08 for currency settings).
  
  
  
  Review Data Mapping:
  
  Verify the mapping of currency fields in the migration or conversion tool. Ensure that the source currency fields are correctly mapped to the target currency fields.
  
  
  
  Standardize Currency Keys:
  
  If there are multiple currency keys in the source data, consider standardizing them before the migration. This may involve converting all amounts to a single currency or ensuring that the same currency keys are used across the data.
  
  
  
  Data Cleansing:
  
  Perform data cleansing on the source data to eliminate any inconsistencies in currency keys. This may involve identifying and correcting records with invalid or missing currency keys.
  
  
  
  Consult Documentation:
  
  Refer to the SAP documentation related to the specific migration or conversion tool you are using. There may be specific guidelines or best practices for handling currency-related issues.
  
  
  
  Use SAP Notes:
  
  Check for any relevant SAP Notes that may address this specific error. SAP Notes often provide patches or additional guidance for known issues.
  
  
  
  Testing:
  
  After making the necessary adjustments, perform a test migration to ensure that the error has been resolved.
