SAP ABAP SYNTAX FOR ASSIGN
ASSIGN
Variants
1. ASSIGN f TO
2. ASSIGN (f) TO
3. ASSIGN TABLE FIELD (f) TO
4. ASSIGN LOCAL COPY OF MAIN TABLE FIELD (f) TO
5. ASSIGN COMPONENT idx OF STRUCTURE rec TO
6. ASSIGN COMPONENT name OF STRUCTURE rec TO
Variant 1
ASSIGN f TO
Additions
1. ... TYPE typ
2. ... DECIMALS dec
3. ... LOCAL COPY OF ...
Effect
the field symbol adopts the type and atrributes of the field f at runtime, particularly the conversion exit. Otherwise, when the assignment is made, the system checks whether the type of the field f matches the type of the field symbol
With the ASSIGN statement, the offset and length specifications in field f (i.e. f+off , f+len or f+off(len) ) have a special meaning:
- They may be variable and thus not evaluated until runtime.
- The system does not check whether the selected area still lies within the field f .
- If an offset is specified, but no length, for the field f , the field symbol
adopts the length of the field f . Caution: also points to an area behind the field f . If you do not want this, the offset and length specifications can be in the form ASSIGN f+off(*) TO . . This means that the field symbol is set so that the field limits of f are not exceeded.
- In the ASSIGN statement, you can also use offset and length specifications to access field symbols, FORM and function parameters.
Since the ASSIGN statement does not set any return code value in the system field SY-SUBRC , subsequent program code should not read this field.
Example
DATA NAME(4) VALUE 'JOHN'.FIELD-SYMBOLS . ASSIGN NAME TO . WRITE . Output: JOHN
Example
DATA: NAME(12) VALUE 'JACKJOHNCARL', X(10) VALUE 'XXXXXXXXXX'.FIELD-SYMBOLS . ASSIGN NAME+4 TO . WRITE . ASSIGN NAME+4(*) TO . WRITE .
Output: JOHNCARLXXXX JOHNCARL
Example
DATA: NAME(12) VALUE 'JACKJOHNCARL', X(10) VALUE 'XXXXXXXXXX'.FIELD-SYMBOLS . ASSIGN NAME+4 TO . WRITE . ASSIGN NAME+4(*) TO . WRITE .
Output: JOHNCARLXXXX JOHNCARL
Addition 1
... TYPE typ
Effect
With typed field symbols, this addition should only be used if the type of the field f does not match the type of the field symbol
Note
This statement results in a runtime error if the specified type is unknown or does not match the field to be assigned (due to a missing alignment or an inappropriate length).
Example
DATA LETTER TYPE C.FIELD-SYMBOLS . ASSIGN LETTER TO .
The field symbol has the type C and the output length 1.
ASSIGN LETTER TO TYPE 'X'. The field symbol has the type X and the output length 2.
Addition 2
... DECIMALS dec
Effect
This addition only makes sense when used with type P. The field symbol contains dec decimal places.
Example
Output sales in thousands:
DATA SALES_DEC2(10) TYPE P DECIMALS 2 VALUE 1234567.FIELD-SYMBOLS . ASSIGN SALES_DEC2 TO DECIMALS 5. WRITE: / SALES_DEC2, / .
Output:
1,234,567.00
1,234.56700
Note
This statement results in a runtime error if the field symbol has a type other than P at runtime or the specified number of decimal places is not in the range 0 to 14.
Addition 3
... LOCAL COPY OF ...
Effect
With LOCAL COPY OF , the ASSIGN statement can only be used in subroutines. This creates a copy of f which points to the field symbol.
Note
(3.5)

Is there any limitation while using external assign in a badi? i currently have the problem that an external assign is not working within a badi. But the programm name is in the calling stack.
