Project history
Corrective and evolutionary tickets on ECC custom objects, delivered on demand alongside other engagements.
Evolutionary and corrective ABAP developments on the Italian invoicing chain and fleet management: rewrite of the daily B2B e-invoice download job (memory dumps eliminated, parametrised test mode), suite of fleet cost / supplier master / duplicate-invoice control reports with staging tables, ALV navigation and subtotals. Split of long-running reports into elaboration and read-only viewer programs to remove multi-hour runtimes; enhancements on SD/FI custom objects; support to the EHP5 to EHP8 upgrade.
Evolutionary maintenance for measurement-transformer manufacturing: MM/PP/QM logistics custom developments.
