The algorithm for the initial balance, total amount in the current period, and total amount in the current year.

For example, the interface is selected as data from 1 to December. Rangetable

 

If rangetable-Low = '1 '.
T_BODY-SGTXT = 'beginning of the year '.
Else.
Rangetable-Low = 'opening balance '.
Endif.

Perform get_faglflext. "Get the number of the beginning or the beginning of the year and append a data entry to the ALV internal table.

 

While month <rangetable-low.

  Perform get_date. "Calculate the first and last days of the current month.

Perform get_faglflexa. "Put detailed data into the inner table it_tab.

Loop at it_tab.

"Append data into the ALV internal table

"Accumulated this month

Endloop.

"APPEND accumulative data for the current period is added to the ALV internal table for a small amount of processing this year

Endwhile.

 

Hope someone can understand it.
