The problem: “How in ABAP get last day of month SAP ?” and first month in ABAP is not uncommon. For example, display orders for the current month, regardless of what date it is today. Or calculate the turnover for this month and so on.

Adding/subtracting a month to/from a date in SAP ABAP can be done with the FM MONTH_PLUS_DETERMINE. Operations with months are not so frequent, but just as useful. For example, calculate the end date of a contract that expires in half a year. In order to subtract the desired number of months, we simply pass a negative number to the months parameter.

Using the function module DAYS_BETWEEN_TWO_DATES we can quickly get the result as the difference between dates in days. You can count the days until the end of the payment term or calculate the number of days until the end of the contract and much more.

ABAP add days to date. Add / subtract days/hour from a date in ABAP or add them to a very useful functionality that can be implemented using the function module TZTF_ADD_DAY. Calling this FM will allow, for example, to receive data for the last n days, where n is entered by the user, or to find the end date of the reserve, which, for example, is 14 days after the order SAP CRM, and much more.
