my code for deleteing file:

OPEN DATASET file FOR INPUT IN TEXT MODE ENCODING DEFAULT.

DELETE DATASET file.

CLOSE DATASET file.

code for writing the data to file:

OPEN DATASET file1 FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.

• LOOP AT result.

• CLEAR:wa1.

• CONCATENATE result-mat1 ',' result-mat2 ',' result-type ',' result-message INTO wa1.

Hi,

For deleteing dataset it is not required to open and close the dataset:

OPEN DATASET file FOR INPUT IN TEXT MODE ENCODING DEFAULT.
IF SY-SUBRC EQ 0.
READ DATASET...
CLOSE DATASET file.
DELETE DATASET file.
ENDIF.

For writing the data to file in CSV format you need to use the concatenate statement and to insert the comma between the fields:

OPEN DATASET file1 FOR OUTPUT IN TEXT MODE ENCODING DEFAULT.

 LOOP AT result.
 CLEAR:wa1.
 CONCATENATE result-mat1 result-mat2 result-type result-message INTO wa1 SEPRATED By ','.
 TRANSFER wa1 TO file1.
 ENDLOOP.

CLOSE DATASET file1.
