it can be used for data insertion and baselining when comparing data. For each loop the row read is assigned to a work area (wa) or field-symbol (Here is the output of the sample ABAP program featuring ABAP Loop At New and At End statements. The BASE operator is used as a baseline for ABAP operations and has multiple uses. In this sample ABAP program, I used the Loop At End for closing the bracket containing the list of sales order item positions. LOOP AT END statement also detects the different vbeln number and enables ABAP developers to do work with the previous structure in the loop. And a bracket is opened for the item positions of that sales order. When a new VBELN Sales Order number is detected in the loop, the order number is printed.
So you need something like: loop at lt assigning#Abap 7.4 loop at itab code
Within the Loop command, AT NEW statement detects when the VBAP structure has a different VBELN (document number) then the previous one. The return code is set after the loop (same for select and other loop structures). Write :/ 'Sales document ', LS_VBAP-VBELN, ' with item(s) ('.Īs a summary, above sample ABAP program SELECT a list of sales items from VBAP table and lists all of them using ABAP Loop command. For me, it’s a very clean code. For more details, I recommend a read on at Help SAP for Iteration Expressions.Select * from VBAP into table LT_VBAP up to 1000 rows. Probably I can get the same result without using LOOP in any way ( it’s for you to think ). versions <7.4 we all know how painful it is to LOOP the first internal table. netwr = REDUCE netwr( INIT val TYPE netwr ABAP 7.4 and beyond 11 : Concatenation, ALPHA and ITAB Lines WebNov 4.

The reading is based on a table, so you can use the FILTER operator, for example, to generate the internal table with only the desired items. Depending on how (in)efficiently such a custom loop is implemented it may even be faster.

2021 For Loop for Internal Tables Keyword LET Nested For Loops Visit ABAP 7.4+. According to Horst Keller, one of the SAP designers of the new ABAP 7.40 release, the performance of GROUP BY loops is likely to be the same as a manual implementation of these LOOPs. That is, instead of making a LOOP inside LOOP between two tables, you can use REDUCE to directly access the items you need to read. Copying an Internal Table into another Internal Table - SAP WebJun 15. With REDUCE it is possible to do a mathematical operation grouping by the items of a certain table for example. I don’t want to stay repeating Horst Keller, but some ABAPers still come to me: “I never had to use REDUCE…”Īn expression with the REDUCE reduction operator creates a result of a specified data type using the type of one or more condition expressions.Ī new and more performative way to not use LOOP AT NEW, for example ( ok ok. I exaggerated in the title, but it isn’t at all a lie.
