Evidence first, then the fix

Built for an industrial company. For confidentiality, the company name, logo, product/part codes and internal data are not shared; images are cropped accordingly.

The need

An error in live SAP can stop payroll, the exchange-rate import or the sales process. A hasty configuration change can create a new problem instead of solving it; the real cause has to be found first.

The solution

Payroll posting error: the cause was not the account setup but 3 employees' cost-distribution records pointing to the wrong cost centre. The records were fixed and the configuration was left untouched.
Missing exchange rates: the daily rate import treated a weekend file that does not exist as a "connection error" and stopped. A missing day was filled by a correctly dated background run; all 104 rates written matched the central bank data.
Quote-to-order job review: reading the source code revealed two logic bugs, reported to the owners: an exclusion condition that was always true and an order type carried over from the previous item.
Bulk master-data maintenance: sales views were opened for 3,733 materials in the simulation system, with every step logged.
Cost check spreadsheet: the cost team's spreadsheet was compared with SAP line by line; every amount matched SAP, and only the spreadsheet's allocation formula was corrected.
