Hi all,

I am using a parameter to get a file name(file path) inorder to upload a file from a legacy system.

my query is how to validate the file type ie it should upload only .txt file type only . if u give other than this file type it should through a error message.

can any one suggest me a good coding.

PARAMETERS : P_FILE TYPE RLGRAP-FILENAME.

regards

hi paul,

you can do something like this..

PARAMETERS : P_FILE TYPE RLGRAP-FILENAME.
DATA LEN TYPE I.
DESCRIBE FIELD P_FILE LENGTH LEN.

LEN = LEN - 3.
IF P_FILE+LEN(3) NE 'txt'.
 message e000(zmsg) with 'enter only text files'.
endif.
