Type error using WS_UPLOAD

[Former Member]

Hi,

I am currently learning ABAP/4.

The following is my source code (i am aware that WS_UPLOAD has become obsolete, though i am running on 4.6):

REPORT ZBDC_1 .

PARAMETERS BDCFILE(80)

DEFAULT 'C:\BDC_file.txt'

lower case.

DATA: BEGIN OF IT_1,

SS(9),

FNAME(40),

CITY(30),

STATE(2),

ZIPCODE(5),

HOMEPHONE(10),

WORKPHONE(10),

At runtime, i get the following error:

Type conflict when calling a function module.

The call to the function module "WS_UPLOAD" is incorrect:

The function module interface allows you to specify only fields of a parameter type under "FILENAME". The field "BDCFILE" specified here has a different filed type.

I have approached this problem from every possible point, but nothing helps.

What can i do to prevent this from happening? How do i fix this?

Many thanks,

can u change the declaration and check again

PARAMETERS BDCFILE(80)

to parameters BDCFILE LIKE RLGRAP-FILENAME.

Thank you.

Everything works as expected.

Hi,

Define the file path like this

PARAMETERS: p_bdcfile type RLGRAP-FILENAME DEFAULT 'C:\BDC_FILE.TXT'.
