There is FM GUI_UPLOAD which will help you in this.
Its has got one parameter calles has_field_separator . Here you can pass comma. So that this will take care while uploading the data in Internal table.

CALL FUNCTION 'GUI_UPLOAD'

filetype = 'ASC'
has_field_separator = ','
* HEADER_LENGTH = 0
* READ_BY_LINE = 'X'
* DAT_MODE = ' '
* CODEPAGE = ' '
* IGNORE_CERR = ABAP_TRUE
* REPLACEMENT = '#'
* CHECK_BOM = ' '
* IMPORTING

invalid_type = 5
no_authority = 6
unknown_error = 7
bad_data_format = 8
header_not_allowed = 9
separator_not_allowed = 10
