1. MODIFY LINE n.
2. MODIFY LINE n OF CURRENT PAGE.
3. MODIFY LINE n OF PAGE m.
4. MODIFY CURRENT LINE.
Variant 1
MODIFY LINE n.
Additions
1. ... INDEX idx
2. ... LINE FORMAT fmt1 ... fmtn
3. ... FIELD VALUE f1 FROM g1 ... fn FROM gn
4. ... FIELD FORMAT f1 fmt11 ... fmt1m ... fn fmtn1 ... fmtnm
Effect
Changes the n th line of the list. This could be,
for example, after line selection ( AT LINE-SELECTION , AT
PFxx , AT USER-COMMAND ).
The current contents of the system field SY-LISEL are restored
to the list as the line contents and the HIDE area for the line
is re-determined from the current contents of the fields hidden with
HIDE .
The return code value is set as follows:
SY-SUBRC = 0
Line was successfully changed.
SY-SUBRC <> 0
Line does not exist.
Note
With multiple-level line selection, the modification is
always performed in the list where the (last) line selection was made,
except in the case of the addition ... INDEX idx and MODIFY
CURRENT LINE (see below).
Addition 1
... INDEX idx
Effect
Changes the relevant line in the list to list level
idx (0, 1, 2, ...) with multiple line selection
( SY-LSIND ).
Addition 2
... LINE FORMAT fmt1 ... fmtn
Effect
The output format of the selected line is determined by
the format specifications fmt1 , fmt2 ... . For a list of
valid format specifications, see
FORMAT .
Example
DATA I TYPE I VALUE 2.
WRITE: / 'Intensified' INTENSIFIED,
'Input' INPUT,
'color 1' COLOR 1,
'intensified off' INTENSIFIED OFF.
* Line selection
AT LINE-SELECTION.
MODIFY CURRENT LINE
LINE FORMAT INVERSE
INPUT OFF
COLOR = I.
After you have selected the the output list line (by
double-clicking), the whole line is set to COLOR 2 and
INVERSE and all INPUT fields are set to INPUT OFF .
The fields with the attribute INTENSIFIED or INTENSIFIED
OFF retain this because the attribute is not addressed here.
Addition 3
... FIELD VALUE f1 FROM g1 ... fn FROM gn
Effect
Overwrites the contents of the fields f1 ,
f2 , ... in the list line with the current contents of the fields
g1 , g2 , ... (type conversion as for
MOVE g1 , g2 , ... to type
C). The field contents of f1 , f2 , ... themselves remain
unchanged.
Notes
If a field (e.g. f2 ) is output several times in
the line to be modified, only the first occurrence is modified. If the
field is not output in the line at all, it is ignored.
You can omit the addition FROM g2 if the field f2 in
the list line is to be modified from the current contents of f2 .
This means that
... FIELD VALUE f2
has the same effect as
... FIELD VALUE f2 FROM f2
The return code value of SY-SUBRC is not affected by the
addition FIELD VALUE and so only depends on the existence of the
selected list line.
Addition 4
... FIELD FORMAT f1 fmt11 ... fmt1m
... fn fmtn1 ... fmtnm
Effect
Modifies the output format of the field f1
according to the format specifications fmt11 ... fmt1m .
Similar to f2 , ..., fn . For a list of valid format
specifications, see FORMAT . Fields
that occur several times or not at all in the line are treated as in
the addition FIELD VALUE .
Notes
If you combine the additions LINE FORMAT and
FIELD FORMAT , the format set by LINE FORMAT is always
valid for the whole line initially. Afterwards, it is changed by the
format specifications for the individual fields.
Example
DATA: FLAG VALUE 'X',
TEXT(20) VALUE 'Australia',
I TYPE I VALUE 7.
FORMAT INTENSIFIED OFF.
WRITE: / FLAG AS CHECKBOX, TEXT COLOR COL_NEGATIVE.
AT LINE-SELECTION.
MODIFY CURRENT LINE
LINE FORMAT INTENSIFIED
FIELD VALUE FLAG FROM SPACE
FIELD FORMAT FLAG INPUT OFF
TEXT COLOR = I.
When the user selects the displayed list line by double-clicking, the
checkbox for FLAG is reset and can no longer accept values. The
format of the entire line is set to "intensified" and TEXT is
displayed in a different color.
Variant 2
MODIFY LINE n OF CURRENT PAGE.
Additions
1. ... FIELD VALUE f1 FROM g1 ... fn FROM gn
2. ... LINE FORMAT fmt1 .. fmtn
3. ... FIELD FORMAT f1 fmt11 ... fmt1m ... fn fmtn1 ... fmtnm
Effect
Changes the n th line on the current page (stored
in the system field SY-CPAGE ).
Addition 1
... FIELD VALUE f1 FROM g1 ... fn FROM gn
Addition 2
... LINE FORMAT fmt1 .. fmtn
Addition 3
... FIELD FORMAT f1 fmt11 ... fmt1m
... fn fmtn1 ... fmtnm
Effect
See MODIFY LINE
Variant 3
MODIFY LINE n OF PAGE m.
Additions
1. ... FIELD VALUE f1 FROM g1 ... fn FROM gn
2. ... LINE FORMAT fmt1 ... fmtn
3. ... FIELD FORMAT f1 fmt11 ... fmt1m ... fn fmtn1 ... fmtnm
Effect
Changes the n th line on page m .
Addition 1
... FIELD VALUE f1 FROM g1 ... fn FROM gn
Addition 2
... LINE FORMAT fmt1 ... fmtn
Addition 3
... FIELD FORMAT f1 fmt11 ... fmt1m
... fn fmtn1 ... fmtnm
Effect
See MODIFY LINE
Variant 4
MODIFY CURRENT LINE.
Additions
1. ... FIELD VALUE f1 FROM g1 ... fn FROM gn
2. ... LINE FORMAT fmt1 ... fmtn
3. ... FIELD FORMAT f1 fmt11 ... fmt1m ... fn fmtn1 ... fmtnm
Effect
Changes the last line read (with line selection or
READ LINE ), even across line levels.
This variant is especially useful if the line to be modified has been
read immediately before through line selection or using
READ LINE . You then need to note the
number of the line until the MODIFY .
Addition 1
... FIELD VALUE f1 FROM g1 ... fn FROM gn
Addition 2
... LINE FORMAT fmt1 ... fmtn
Addition 3
... FIELD FORMAT f1 fmt11 ... fmt1m
... fn fmtn1 ... fmtnm
