How To Fix FMCF171 - Value '&1' of parameter '&2' is critical with large amounts of data

SAP Error Message - Details

• Message type: E = Error

• Message class: FMCF -

• Message number: 171

• Message text: Value '&1' of parameter '&2' is critical with large amounts of data

What causes this issue?

You have activated cascaded parallel processing, in other words, the
data selection is divided between several dialog processes. At the same
time you have chosen the value'&V1&' for the parameter '&V2&. This can
increase runtime.
For a good performance, the following prerequisites should be met when
processing large amounts of data:
The <DS:DE.FM_CCF_FMTOT>update of the FM totals records</> should be
deactivated. Note that the FM totals records must be reconciled once the
program run has finished.
The <DS:DE.FM_CCF_FMTOT>update of the fiscal year change totals records
</> should be deactivated. Note that the fiscal year change totals
records must be reconciled once the program run has finished.
The <DS:DE.FM_CCF_AVC>update of the assigned values</> should be
deactivated. Note that in this case the assigned values must be
reconstructed once the program run has finished (and after reconciling
the FM totals records if applicable) for both fiscal years.
The <DS:DE.FM_CCF_ENQDC>individual document blocks</> should not be set.
Otherwise the block server can be overloaded.
The <DS:DE.FM_CCF_ITEMLOG>detail list</> should not be chosen. as this
can cause overflow of the main memory

• What is the cause and solution for SAP error message FMCF171 - Value '&1' of parameter '&2' is critical with large amounts of data ?

  The SAP error message FMCF171 indicates that a specific parameter value is considered critical when processing large amounts of data. This error typically arises in the context of financial or controlling modules, where certain thresholds or limits are exceeded during data processing.
  Cause:
  
  Parameter Value Exceeded: The value of the specified parameter (&2) has reached a critical threshold (&1), which may indicate that the system is unable to handle the volume of data being processed.
  Performance Issues: Large datasets can lead to performance bottlenecks, causing the system to flag certain operations as critical to prevent potential failures or data integrity issues.
  Configuration Settings: The system may have specific configuration settings that define what constitutes a "critical" value for certain parameters, and these settings may need to be reviewed.
  
  Solution:
  
  Review Parameter Settings: Check the configuration of the parameter (&2) in the relevant transaction or configuration settings. Adjust the threshold values if necessary to accommodate larger datasets.
  Optimize Data Processing: If possible, break down the data processing into smaller batches to avoid hitting critical thresholds. This can help in managing the load on the system.
  Performance Tuning: Analyze the performance of the system and consider tuning database queries, indexes, or other performance-related settings to improve handling of large datasets.
  Consult Documentation: Refer to SAP documentation or notes related to the specific module you are working with for any known issues or recommended practices regarding handling large amounts of data.
  Contact SAP Support: If the issue persists, consider reaching out to SAP support for assistance. They may provide patches or additional guidance based on the specific version of SAP you are using.
  
  Related Information:
  
  Transaction Codes: Depending on the context, you may need to look into specific transaction codes related to financial or controlling processes (e.g., FBL1N, FBL3N, etc.).
