6 2 Basics The sections of this chapter make you familiar with the basic ABAP statements that you can use in the web-based editor of the SAP Fiori app Custom Fields and Logic. 2.1 IF, ELSEIF, ELSE, ENDIF Syntax Syntax IF log_exp1. [statement_block1] [ELSEIF log_exp2. [statement_block2]]... [ELSE. [statement_blockn]] ENDIF. These statements define a control structure which can contain multiple statement blocks statement_block of which a maximum of one is executed in conjunction with logical expressions log_exp. After IF and ELSEIF, any logical expression log_exp can be executed while the expressions statement_block represent any statement block. The logical expressions, beginning with the IF statement, are checked from top to bottom and the statement block is executed after the first true logical expression. If none of the logical expressions are true, the statement block after the ELSE statement is executed. Example Sample Code " Example: Retrieving and formatting the current time " " We need to resort to GET TIME STAMP FIELD var and " extract the time from the timestamp. DATA current_time TYPE timestamp. DATA timezone TYPE timezone. DATA time TYPE t. DATA result TYPE string. " Get the current date and time as a timestamp (with seconds accuracy) SAP SE or an SAP affiliate company. All rights reserved. Basics

7 GET TIME STAMP FIELD current_time. " Extract the time part from the timestamp. " timezone is initial (empty), which means the time will be returned in the default timezone, UTC. CONVERT TIME STAMP current_time TIME ZONE timezone INTO TIME time. " Convert time to the 12-hour format IF time < '120000'. result = { time TIME = ISO } AM. ELSEIF time > '120000' AND time < '240000'. result = { CONV t( time - 12 * 3600 ) TIME = ISO } PM. ELSE. result = High Noon. ENDIF. " result => 10:35:08 AM Basics 2015 SAP SE or an SAP affiliate company. All rights reserved. 7
