If there are other commands between the READ and the usage of SY-TFILL, there is always the danger of a change of the system variable. Copying an Internal Table into another Internal Table - SAP WebJun 15. I recommend the usage SY-TFILL only, if you need it direct after the READ(1). Depending on how (in)efficiently such a custom loop is implemented it may even be faster. Please get attention of the value 0 for the 2nd entry: SY-TFILL is not updated with each step, only after the first loop. 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. WRITE: / 'sy-tfill = ', sy-tfill, 'in loop with', pf_exclude. WRITE: / 'sy-tfill = ', sy-tfill, 'after read table'. 'Code in focus READ TABLE itsbook TRANSPORTING NO FIELDS WITH KEY carrid AA. 'Select data from sbook table SELECT FROM sbook INTO TABLE DATA (itsbook). This can also be done using READ TABLE as below. READ TABLE pf_exclude INDEX 1 TRANSPORTING NO FIELDS. LINEEXISTS is used to check whether a record exists in internal table or not. WRITE: / 'sy-tfill = ', sy-tfill, 'after describe table'.

AnotherĮxecutable example demonstrates how the entire group loop can be implemented using expressions.Beside the recommended DESCRIBE TABLE LINES Target will be based on source, where the fields have the same name, otherwise the MAPPING will be used (target-field2 will be source-field1, etc. MAPPING statement: itabtarget CORRESPONDING ( itabsource MAPPING field2 field1 field4 field3 ).

As we are doing in the old abap statement The below highlighted is an Deep Structure. The values in the second column are random numbers between 1 and 100. ABAP 7.4 Loop Statement 1911 Views Follow RSS Feed Hi, I want to Loop the record and need to append in the new internal Table. The example enables a maximum number of different key values and rows in the internal table to be entered. The output is the group members and the associated aggregates. Table numbers is used to group by the content of the column key.įor the groups, the usual SQL aggregates sum, maximum, minimum, and average are calculated for the secondĬolumn num. s ing the FOR Ite r a tion Ex pr e s s ion in B A P 7. As you can see weaccomplished the same goal with way fewer lines of code. OK, so let’s take a look at these inside the debugger. CORRESPONDING in ABAP 7.4 This constructor operator can be used to move data between two internal tables with a different set of columns. The same applies to the syntax of the additions result and cond as to a loop across rows with the exception that the addition TRANSPORTING NO FIELDS cannot be specified. Numbers = VALUE #( FOR j = 1 UNTIL j > lines With ABAP 7.4 DATA(itab) VALUE titab ( ( 10 ) ( 20 ) ( 30 ) ). This variant of the statement LOOP AT itab groups the rows of the internal table and executes a loop across the groups. Seed = CONV i( sy-uzeit ) min = 1 max = keys ).ĭATA(rnd_num) = cl_abap_random_int=>create( DATA (lwstatush) ltstatush sddoc lwheader-docnumber.

Hi All, Please help me to understand how to use the IF condition inside a FOR iteration and populate values in ABAP 7.4 The below is with mix of old and new syntax. GROUP BY ( key = -key count = GROUP SIZE ) Either all the rows are read or cond conditions are specified. The table key with which the loop is executed can be determined in cond. The output response result determines how and to where the row contents are read. SPLIT xstr AT CONV xstring ( 20 ) INTO TABLE DATA (xtab) IN BYTE MODE. This variant of the statement LOOP AT itab executes the statement block between LOOP and ENDLOOP once for each read row. DATA (xstr) clabapcodepage>convertto ( Like a Hurricane ). Itab TYPE STANDARD TABLE OF line WITH EMPTY KEY. The byte string xstr is split at bytes with the value hexadecimal 20, which stands for a blank in code page UTF-8, into an internal table with row type xstring. This example demonstrates a grouping with aggregates.
