Does you business requirement needs single line item in ALV to be displayed in multiple rows/lines for better readability? You then surely need a multi-line ALV, which can be implemented by just a simple tweaking in your ALV field catalog.

You can achieve this objective using property ROW_POS of Field catalog. Just assign a value between 1 to 3 to each of the records (denoting output internal tables columns/fields) in field catalog. Thats it. Value is restricted between 1 and 3 since ALV can handle maximum of 3 rows for 1 ALV line item.
The example followed will completely clear the usage.

Here is the code to build the field catalog of an ALV.

Code:
FORM e01_fieldcat_init USING e01_lt_fieldcat TYPE slis_t_fieldcat_alv.
DATA: ls_fieldcat TYPE slis_fieldcat_alv.
ls_fieldcat-fieldname = CARRID.
ls_fieldcat-key       = X.
ls_fieldcat-ref_fieldname = CARRID.
ls_fieldcat-ref_tabname = SFLIGHT.
ls_fieldcat-row_pos = 1.
APPEND ls_fieldcat TO e01_lt_fieldcat.
CLEAR ls_fieldcat.
ls_fieldcat-fieldname = CONNID.
ls_fieldcat-key       = X.
ls_fieldcat-ref_fieldname = CONNID.
ls_fieldcat-ref_tabname = SFLIGHT.
ls_fieldcat-row_pos = 1.
APPEND ls_fieldcat TO e01_lt_fieldcat.
CLEAR ls_fieldcat.
ls_fieldcat-fieldname = FLDATE.
ls_fieldcat-key       = X.
ls_fieldcat-ref_fieldname = FLDATE.
ls_fieldcat-ref_tabname = SFLIGHT.
ls_fieldcat-row_pos = 1.
APPEND ls_fieldcat TO e01_lt_fieldcat.
CLEAR ls_fieldcat.
ls_fieldcat-fieldname = PRICE.
ls_fieldcat-ref_fieldname = PRICE.
ls_fieldcat-ref_tabname = SFLIGHT.
ls_fieldcat-row_pos = 2.
APPEND ls_fieldcat TO e01_lt_fieldcat.
CLEAR ls_fieldcat.
ls_fieldcat-fieldname = CURRENCY.
ls_fieldcat-ref_fieldname = CURRENCY.
ls_fieldcat-ref_tabname = SFLIGHT.
ls_fieldcat-row_pos = 2.
APPEND ls_fieldcat TO e01_lt_fieldcat.
ENDFORM.

FORM e01_fieldcat_init USING e01_lt_fieldcat TYPE slis_t_fieldcat_alv.

DATA: ls_fieldcat TYPE slis_fieldcat_alv.

ls_fieldcat-fieldname = CARRID.

ls_fieldcat-key       = X.

ls_fieldcat-ref_fieldname = CARRID.

ls_fieldcat-ref_tabname = SFLIGHT.

ls_fieldcat-row_pos = 1.

APPEND ls_fieldcat TO e01_lt_fieldcat.

CLEAR ls_fieldcat.

ls_fieldcat-fieldname = CONNID.

ls_fieldcat-key       = X.

ls_fieldcat-ref_fieldname = CONNID.

ls_fieldcat-ref_tabname = SFLIGHT.

ls_fieldcat-row_pos = 1.

APPEND ls_fieldcat TO e01_lt_fieldcat.

CLEAR ls_fieldcat.

ls_fieldcat-fieldname = FLDATE.

ls_fieldcat-key       = X.

ls_fieldcat-ref_fieldname = FLDATE.

ls_fieldcat-ref_tabname = SFLIGHT.

ls_fieldcat-row_pos = 1.

APPEND ls_fieldcat TO e01_lt_fieldcat.

CLEAR ls_fieldcat.

ls_fieldcat-fieldname = PRICE.

ls_fieldcat-ref_fieldname = PRICE.

ls_fieldcat-ref_tabname = SFLIGHT.

ls_fieldcat-row_pos = 2.

APPEND ls_fieldcat TO e01_lt_fieldcat.

CLEAR ls_fieldcat.

ls_fieldcat-fieldname = CURRENCY.

ls_fieldcat-ref_fieldname = CURRENCY.

ls_fieldcat-ref_tabname = SFLIGHT.

ls_fieldcat-row_pos = 2.

APPEND ls_fieldcat TO e01_lt_fieldcat.

ENDFORM.


The ALV with the above field catalog gives the following multi-lined ALV output.

All the columns with row_pos as 1 in the field catalog are appearing in 1st row where as the ones with row_pos as 2 are appearing in the 2nd row, even though they are one single line item in the ALV output internal table.
