In ECC, this will not be directly visible as Asset Accounting and GL are not ‘’merged’’ but once in S4, the reporting in GL will also be impacted. Program RAFABNEW is still available in New Asset Accounting in ECC.

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


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