Program RAFABNEW is still available in New Asset Accounting in ECC.

  • SAP Note 2405554

Conversion error, during conversion the following error message appears: R21- FINS_RECON795 – Line Items ANEP/ANEA differs from Totals ANLC

Standard RAFABNEW is a template program and the recommendation is to check if it should be used as it is or should rather be adjusted.

If not adjusted, it will use different exchange rates:

• ANLC – first acquisition date
• ANEP/ANEA – asset value date

Action:

• Execute the programs ZACORR110 and ZACORR55 included in the following note:

• Create a new Chart of Depreciation and use the below pilot note to change the assignment of the company code to the chart of depreciation
• Recommended Notes
  • SAP Note 2152452

Conversion to SAP S/4HANA Finance Performance

Performance issues with Program, Tcodes or Queries: System is slow in general due to problem with CPU, MEMORY. I/O or table locks, use HANA_Configuration_MiniChecks script to check and follow recommended notes depending on issue found with configuration script.
