Project: Performance Optimization of Slow Software

Analyzing slow programs running on SAP system and optimizing for the speed and saving the hardware resources.

Technology Used:

  • Analyzing programs using SAP performance optimization transactions
    • SE50 / SE51
    • SAT / ST12
    • ST05 
  • Replacing inefficient SQL statements with efficient statements
  • Replacing inefficient logic with optimized logic
    • Internal tables declarations from Standard internal tables to sufficient types
    • Sorting of internal tables when needed
    • Pre-loading unnecessary duplicate loads from the database
    • Changing standard declarations to field symbols wherever it makes sense

Project: Dynamic migration program

Creating a dynamic program that uploads data from CSV files into SAP database tables.

Based on the name and structure of the CSV file, program imports data into the tables in a stable and optimized way.

Technology Used:

  • Field symbols
