When you leave the loop, sy-tabix has the same value as when you entered it. Otherwise, it is 4. The loop may not contain any operations on entire internal tables that change the table. However, you should remember that even saving a global internal table with the LOCAL statement in a procedure is a change operation on the entire table, since it exchanges the table contents.
When you call procedures within loops, you should therefore check that it does not change the entire internal table. If you change the table, the loop can no longer work properly. If you insert or delete a table entry within a loop pass, it is taken into account in subsequent loop passes as follows:. The processing option specifies how a table line is available in the statement block of the list.
The contents of the table lines must be convertible into the data type of the work area wa. In each loop pass, one line of the table is copied into the work area.
The end of the loop does not affect the work area, that is, the contents of wa are the same after the ENDLOOP statement as they were in the final loop pass. If no table entries are processed in the loop, because the table is entry, or no line meets the condition cond, the work area is not changed. To assign the contents of the current loop line to a field symbol, specify result as follows:. If the line type is structured, you should specify the same type for the field symbol when you declare it.
This allows you to address the components of the field symbol. If you cannot specify the type statically, you must use further field symbols and the technique of assigning components of structures to address the components of the structure.
The end of the loop does not affect the field symbol, that is, after ENDLOOP it is still assigned to the same line as in the final loop pass. If no table entries are processed in the loop, because the table is entry, or no line meets the condition cond, the field symbol is not changed. For further information about assigning table lines to field symbols, refer to Access Using Field Symbols.
Suppressing the Assignment of Lines. If you do not need to transfer the contents of the current table line to a work area or assign them to a field symbol, you can use the following statement:. This form of the LOOP statement is useful if you want to find the index of a particular internal table in the system field sy-tabix, or the number of rows in a table that meet a particular condition.
To avoid reading all of the lines in an internal table, you can specify a condition for the line selection as follows:. This processes all of the lines that meet the logical condition cond. The logical expression cond can consist of more than one comparison. In each comparison, the first operand must be a component of the line structure. The comparison then applies to the entire line. Control level processing is allowed within a LOOP over an internal table.
This means that you can divide sequences of entries into groups based on the contents of certain fields. Internal tables are divided into groups according to the sequence of the fields in the line structure. The first column defines the highest control level and so on. Line 18 reorders the rows so that the values of t are in ascending order. Hello, we used very similar code in a report we developed to download data into excel with several sheets. This can be used with loopendloop or with describe table.
This data type has a default length of one and a blank default value. Collect sets sy tabix to the index of the existing or inserted line in the table. May 15, for wa in itab index into idx cond this effectively causes a loop at itab. The system finds existing lines using the hash algorithm of the internal table.
You can use sytabix field while processing your results in loop. For this reason, when working on the 2nd edition on the abap introduction book, we have revised the section on binary search to advise against using it. But either not set or set 0 index for hashed table. Sams teach yourself abap4 in 21 days day 11 internal tables. The system field sytabix contains the index of the line inserted or modified in the collect statement.
Please below an explanation of the system variables sytabix and syindex. You can use ticket system for all your problems regarding sap module, abap and basis.
Loop at sets sy tabix to the index of the current line at the beginning of each loop loss. In this blog, i will try to explain most useful functions added in abap editor from my point of view and will try to collect links to other useful resources related to abap editor for sap gui do not expect too much in the beginning, but the list will grow up on demand.
So youre an experienced abap programmer wanting to leverage off the fantastic new functionality available to you in abap 7. After the collect statement, the system field sytabix has the value. In this articles, i will try to details the most used abap popup window kind with sample sap.
The row number from sytabix appears on the left of the output. If the search is successful, sysubrc is set to 0, and sytabix is set to the index of the table line in which the string was found. Sy tabix sy tabix contains the current line in an internal table. Box components purpose to reduce the memory needed by abap program. Sy fdpos contains the offset position of the string in the. Mar 01, difference between sytabix and syindex in sap abap sytabix, syindex. Aug 10, index looping in sap august 10, abap performance, code sample, for dummies, tutorials by abapcookbook editor in sap, for better performance, instead of using nested loops, we can use the index looping technique.
It gives examples of classic abap and its equivalent. Loop at sets sytabix to the index of the current line at the beginning of each loop loss. Give disruption, and hit enter, now you will move to following screen. So when you are looping over an internal table, you use sytabix. However, searching for information on this topic leads you to fragmented pages or blogs that refer to only a couple of the new features available to you. August 10, code sample, for dummies, tutorials by abapcookbook editor.
Inserting lines using the index the insert statement allows you not only to insert lines in any. Initial data the program must read the table pa the structure is visible from the se11 transaction and must check all records relating to the company , indicating for each cidemploy if his creation has. If a line is found, the contents of the nonkey fields of the work area are copied into the corresponding fields of the line, and sy subrc is set to 0.
Just copy and past in your system and then execute it. We have abap internal table which is contain two fields lets say main address and secondary address, not all the data have secondary address. Then use that variable for internal table modifications. The field is either not set or is set to 0 for hash tables. If the table has the type hashed table, sytabix is set to 0. Lines through 15 write out the contents of the internal table. The problem if there is no data in the fields, sap system still allocate memory to just.

The sytabix is incremented and the next loop processes the row pointed to by sytabix. Sytabix is set by the statements below, but only for index tables. For instance, if you are in the second loop pass and you insert a record before row 3. If a line is found, the contents of the nonkey fields of the work area are copied into the corresponding fields of the line, and sysubrc is set to 0.
Difference between sytabix and syindex in sap abap. Sy tabix is set by the statements below, but only for index tables. Sujono Riyadi. Pham Van Hai. Ajay Bharadvaj. Oksana Erm. Sarvesh singh. Kiyanga Mbodo.
