We encountered an issue in SAP wherein the variant of the program 'SAPFPAYM' (Create Payment Medium) got updated automatically. The destination folder path got updated from Production to Development. The payments were working fine until 29.06.2022. Surprisingly, on 30.06.2022, all the generated payment files moved to Development file path instead of Production file path causing delays in payment processing. Unfortunately, I am unable to find a history of changes done to the variant and it only shows the last user ID changes in VARID table.
Has anyone experienced this type of realtime issue in production? What could have caused this? What can be done to prevent such issues from happening in future? We tried protecting the fields but that seldom helps.
