Problem in Perform

[Former Member]

I am using Perform to upload two files to two internal table of diffrent structures.

DATA: BEGIN OF itab OCCURS 0,

data(200),

END OF itab.

DATA: BEGIN OF itabtxt OCCURS 0,

f01(4),

f02(10),

f03(18),

f04(3),

f05(3),

f06(6),

f07(25),

f08(10),

f09(20),

f10(8),

f11(50),

f12(10),

f13(12), "+§sr01

END OF itabtxt.

perform load_excel_file using z_x changing itab.

perform load_excel_file using z_x changing itabtxt.

form load_excel_file using p_z_x changing p_itab type table.

data: lzc_filename type string.

lzc_filename = pdatei.

CALL FUNCTION 'GUI_UPLOAD'

EXPORTING

filename = lzc_filename

FILETYPE = 'ASC'

HAS_FIELD_SEPARATOR = p_z_x

IMPORTING

FILELENGTH = bytes

tables

data_tab = p_itab

endform.

I am getting error "Actual Parameter ITAB and Formal Parameters P_ITAB are incompatible". Please try to solve the problem.

in PERFORM statement you should have TABLES parameter to get an internal table

I dont think you can use the same PERFORM to upload data into 2 diff internal tables.

Because you need declare TABLES TYPE <Struct>...where <struct> will eb different for both internal tables.

Use macro for this...give like below

data_tab = &1

when you call macro you can pass itab as parameter

Hi,

Try something like this. You can not using same routine with different change parameters of different types.

DATA: BEGIN OF itab occurs 0,
data(200),
END OF itab.

DATA: BEGIN OF itabtxt,
f01(4),
f02(10),
f03(18),
f04(3),
f05(3),
f06(6),
f07(25),
f08(10),
f09(20),
f10(8),
f11(50),
f12(10),
f13(12), "+§sr01
END OF itabtxt.

perform load_excel_file using z_x changing itab itabtxt.

form load_excel_file using p_z_x changing p_itab type table
                                                              p_itabtxt type table.

data: lzc_filename type string.
lzc_filename = pdatei.

CALL FUNCTION 'GUI_UPLOAD'
EXPORTING
filename = lzc_filename
FILETYPE = 'ASC'
HAS_FIELD_SEPARATOR = p_z_x
IMPORTING
FILELENGTH = bytes
tables
data_tab = p_itab
endform.

Try this :

DATA: BEGIN OF itabtxt OCCURS 0,

f01(4),

f02(10),

f03(18),

f04(3),

f05(3),

f06(6),

f07(25),

f08(10),

f09(20),

f10(8),

f11(50),

f12(10),

f13(12), "+§sr01

END OF itabtxt.

perform load_excel_file tables itab using z_x.

perform load_excel_file tables itabtxt using z_x.

form load_excel_file tables p_itab using p_z_x.

data: lzc_filename type string.

CALL FUNCTION 'GUI_UPLOAD'

EXPORTING

filename = lzc_filename

FILETYPE = 'ASC'

HAS_FIELD_SEPARATOR = p_z_x

tables

data_tab = p_itab.

endform.

Hello Mahesh,

Do not use Tables command in subroutine ,it is performance issue,so call diffrent perform statement that what you have.

I have done trace for this type scenario

Thanks
