Can you insert an extraction of your code (function module interface) ?

FUNCTION ZTESTALV.

So you can t read DEST in your program and you can read the internal table contents ?

Did you already try with "changing"-paramaters instead of "exporting" ?

Perhaps if you mark the "pass by value" checkbox...

( just guessing )

Hi Kris

Changing parameter can't pass an internal table,I must pass an table,so i declare the table ZFLYPLAN in tables parameters

With methods you pass variables/tables via importing/exporting.

Here you have a mixture between function and method.

Think you should use :

call function <functionname>

exporting

importing

tables

exceptions

<exceptions>.

CALL METHOD meth EXPORTING imp1 = var1

IMPORTING exp1 = var2 ...

CHANGING chg1 = var3

var1, var2 and var3 can be declared as table types.

data: var1 type table of ...
