Summing a Program Symbol: SUMMING
The SUMMING command is used for accumulating a total value for a program symbol. The command should be specified just once. Then, each time the specified program symbol is formatted, its current value is added into the total symbol. Several program symbols may all be added into a single total symbol.
/: SUMMING program_symbol INTO total_symbol
SAPscript cannot create the field for the total dynamically. The symbol used must be defined in a TABLES structure in the calling program.
