How To Fix CNV_10520036 - Finished simulation; merges found in &1 out of &2 reconciliation keys

SAP Error Message - Details

• Message type: E = Error

• Message class: CNV_10520 - Conversion module of FI-CA FIKEY-logic

• Message number: 036

• Message text: Finished simulation; merges found in &1 out of &2 reconciliation keys

What causes this issue?

Simulation for this portion of reconciliation keys was finished. In &V1&
out of &V2& reconciliation keys checked by this job merge of the FI-CA
logical key was determined. These reconciliation were marked as merged
by the SLO conversion package.
After the actual conversion is performed these reconciliation keys will
also be flagged in the FI-CA totals control table (activity "Flag
reconciliation keys in FI-CA").

System Response

The system inserts the reconciliation keys in that merged was determined
in the table CNV_10520_FIKEYC. After these entries as transferred into
FI-CA totals control table (DFKKSUMC) after the conversion these
reconciliation keys will have following functional restrictions:
it will not be possible to perform corrections for these reconciliation
keys
the assignment of the posting items to posting totals within FI-CA may
not be entirely correct (corresponding information message will be
available in the report RFKKABS30).

How to fix this error?

No action is required. To verify which reconciliation keys were flagged
by the package &V3& check table CNV_10520_FIKEYC entering package &V3&
as selection criterium.

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 CNV_10520036 - Finished simulation; merges found in &1 out of &2 reconciliation keys ?

  The SAP error message CNV_10520036 indicates that during a simulation of a data migration or conversion process, the system has detected merges in a certain number of reconciliation keys. This message is typically associated with the SAP S/4HANA migration process, particularly when using the SAP S/4HANA Migration Cockpit or other data migration tools.
  Cause:
  The error message suggests that there are multiple records in the source system that are being merged into a single record in the target system. This can happen due to:
  
  Data Duplication: There are duplicate entries in the source data that are being consolidated.
  Data Mapping Issues: The mapping rules defined for the migration may not be correctly set up, leading to unintended merges.
  Inconsistent Data: The source data may have inconsistencies that cause multiple records to be treated as one during the migration process.
  
  Solution:
  To resolve this issue, you can take the following steps:
  
  
  Review the Simulation Results: Analyze the simulation log to identify which reconciliation keys are causing the merges. This will help you understand the nature of the duplicates.
  
  
  Check Data Quality: Ensure that the source data is clean and free of duplicates. You may need to perform data cleansing operations to remove or consolidate duplicate records before migration.
  
  
  Adjust Mapping Rules: Review and adjust the mapping rules in the migration cockpit to ensure that they correctly reflect the intended data structure in the target system.
  
  
  Consult Documentation: Refer to the SAP documentation for the specific migration tool you are using. There may be guidelines or best practices for handling merges and duplicates.
  
  
  Test with Smaller Data Sets: If possible, run the migration simulation with a smaller subset of data to isolate the issue and test different scenarios.
  
  
  Engage with SAP Support: If the issue persists and you cannot identify the cause, consider reaching out to SAP support for assistance. They may provide insights specific to your system configuration and data.
  
  
  Related Information:
  
  Migration Cockpit: Familiarize yourself with the SAP S/4HANA Migration Cockpit, as it provides tools and functionalities for data migration, including error handling and simulation features.
  Data Cleansing Tools: Consider using data cleansing tools or techniques to prepare your data before migration.
  SAP Notes: Check for any relevant SAP Notes that may address this specific error or provide additional guidance on handling data merges during migration.
  
  By following these steps, you should be able to identify the cause of the merges and take appropriate action to resolve the error message CNV_10520036.
