Hi Sunil,

U can split the Filename at '.' and consider the Extension and check it.

SPLIT fname at '.' INTO filename extension.

Filename and extension are character variables here.

Extension contains ur file extension and u can use this for ur validation.

U can validate them on 'AT SELECTION-SCREEN' event.

Hi,

Use split command to split the value in the selection screen at '.' , then check the condition in AT SELECTION SCREEN ON FIELD.

Thanks & Regards

Hi Sunil,

Bhupal is correct. If we put his words into exact ABAP Syntax then following is the way :-

At Selection-Screen On pFile.

• where pFile can be defined as following in the begiining

• Parameters: pFile Like rlgrap-filename Obligatory.

Data: lExt(3) Type c,

lFile Like pcfile-path.

Move pFile To lFile.

CALL FUNCTION 'PC_SPLIT_COMPLETE_FILENAME'

EXPORTING

COMPLETE_FILENAME = lFile

IMPORTING

EXTENSION = lExt.

Translate lExt to Lower Case.

If sy-subrc ne 0 Or

lExt ne 'csv' .

Message e000 With Text-004. "Display a valid message

EndIf.

Instead of using the SPLIT statement the above function module can also be used to achieve the same. The function will extract the extension in the variable 'lExt'. The above examle checks for a 'csv' extension, the same can be used for any other case by changing the comparing value of extension.
