This article describes how to create a dynamic monthly summary ALV report in SAP using RTTS (Run-Time Type Services) to build dynamic tables and structures at runtime. The report summarizes data by year and month, creates dynamic columns for Posting, Expenditure, and GRN, and displays results in an ALV grid dynamically. The code is divided into several steps, including declaring parameters, data declarations, and field symbols, fetching data from the database, determining unique months, creating dynamic table structure, populating the dynamic table, and displaying the ALV report. The code uses RTTS objects such as cl_abap_structdescr and cl_abap_elemdescr to create dynamic columns at runtime.
