Date/time operations in ABAP.

With ABAP, you can do simple date calculations. If you need some advanced things like adding a month (not simple 30 days) to a date, SAP provides many function modules to do the job. Here’s my list of ABAP date functions, their names usually explain what they do:

CALC_DIFF_IN_MONTHS_DAYS
COMPUTE_YEARS_BETWEEN_DATES
DATE_CHECK_PLAUSIBILITY
DATE_COMPUTE_DAY
DATE_CONV_EXT_TO_INT
DATE_CONVERT_TO_FACTORYDATE
DATE_GET_WEEK
DATE_TO_PERIOD_CONVERT
FIRST_DAY_IN_PERIOD_GET
HOLIDAY_GET – holidays list for a plant
L_MC_TIME_DIFFERENCE – Calculate time difference in minutes
LAST_DAY_IN_PERIOD_GET

MONTH_PLUS_DETERMINE
PERIOD_AND_DATE_CONVERT_OUTPUT
RP_ASK_FOR_DATE
