Split a field

Question

Hi all,
I have a field of length 8. I need to split it into components of different lengths. How would i do it in ABAP?

Answer 1

<b>FYI</b>
SPLIT f AT g INTO h1 ... hn.
Extras:
1. ... IN BYTE MODE
2. ... IN CHARACTER MODE
Effect
Splits f wherever the separator g occurs and places the resulting sections into the fields h1 ... hn (n >= 2). Note that if g has type C, the field is used in its defined and not its occupied length.
The field is split using the following procedure: f is split internally into a set of target fields k1 to kn with the same type as f. These are then transferred into the actual target fields h1 to hn using MOVE semantics.
The Return Code is set as follows:
SY-SUBRC = 0:
All of the fields hi (1 <= i <= n) were large enough.
SY-SUBRC = 4:
One of the fields hi was not large enough and significant characters were lost.
Examples
DATA: NAMES(30)    TYPE C VALUE 'Charly, John , Peter',
      NAMES2       TYPE STRING,
      ONE(10)      TYPE C,
      TWO(10)      TYPE C,
      THREE        TYPE STRING,
      FOUR(4)      TYPE C VALUE 'FOUR',
      DELIMITER(2) VALUE ','.
SPLIT NAMES AT DELIMITER INTO ONE TWO.
    ONE contains 'Charly' and TWO contains 'John , Pet'.
    SY-SUBRC is 4, because TWO was not large enough to
    accommodate the whole of the remaining string
SPLIT NAMES AT ',' INTO ONE TWO THREE.
    ONE contains 'Charly', TWO contains ' John',
    THREE contains ' Peter'.
SPLIT NAMES AT ', ' INTO ONE THREE TWO.
    ONE contains 'Charly', THREE contains 'John',
    TWO contains 'Peter'.
CONCATENATE NAMES '' INTO NAMES2 SEPARATED BY SPACE.
SPLIT NAMES2 AT DELIMITER INTO ONE TWO THREE FOUR.
    ONE contains 'Charly', TWO contains 'John',
    THREE contains 'Peter ', FOUR is empty.
SPLIT NAMES2 AT DELIMITER INTO ONE FOUR THREE.
    ONE contains 'Charly', FOUR contains 'John',
    THREE contains 'Peter', SY-SUBRC is 4, since
    FOUR was not large enough (spaces are significant
    characters!)
Addition 1
... IN BYTE MODE
Effect
If you use this addition, all fields must be of the type X or XSTRING.
Addition 2
... IN CHARACTER MODE
Effect
This addition is optional and corresponds to the default setting (see above).
Notes
If the number of target fields is not greater than the number of separator strings in the source string, very little information can be lost. In this case, the last target field contains the "remainder", including the separator string (see first example).
If the source field does not contain the separator string, or if you specify an empty C string as the separator, the entire source field is placed in the first target field.
Any target fields that are not required are deleted.
If f begins with the separator string g, the first target field (h1) contains an initial value.
Variant 2
SPLIT f AT g INTO TABLE itab.
Extras:
As with variant 1
Effect
Similar to variant 1
The sections of f are placed in the internal table itab. The sytsem creates a table row for each section of f.
Note: If f ends with the separator string g, the system does not create an empty table row at the end. This is in contrast to what happens when g occurs at the beginning of f.
Example
TYPES: BEGIN OF ITAB_TYPE,
        WORD(20),
      END   OF ITAB_TYPE.
DATA: ITAB TYPE STANDARD TABLE OF ITAB_TYPE WITH
                NON-UNIQUE DEFAULT KEY INITIAL SIZE 5.
SPLIT 'STOP Two STOP Three STOP   ' AT 'STOP' INTO TABLE ITAB.
ITAB now has three rows. The first is empty, the second contains ' Two', and the third ' Three'.
Note
Performance:
The runtime required for the SPLIT statement in the first example of variant 1 is approximately 15 msn (standard microseconds). If you write the sections of f into an internal table, the runtime is around 30 msn.
