Adding selection criteria to the Function Module!

[Former Member]

Hi,

I am writing code for the Function module which is to be used to extract R/3 data to BW!

i cud extract all the data from R/3 with the FM!

Now i want to have selections in the Function module so that when i run the FM , it should ask me the input vlaues for the specified fields!

i want selection for LIFNR and for that i had used the following code!

-

---

ranges: r_LIFNR_RKWA for lfa1-lifnr.

loop at itab into e_t_data where fieldname = 'lifnr' . ( here e-t_data is the final table in which data should exist )

move corresponding itab to e_t_data.

append r_lifnr_rkwa.

-

---

first of all i am not sure whether the code is correct . can you please anybody here give the correct code and suggest to enhance this code?

it is also giving me syntax error saying fieldname does not exist.

Thanks,

Ravi

Hi Ravi,

You can create a Wrapper FM aound the main FM with the additional selection criteria.

Hi Dharitree,

Can you pls elaborate your answer?

i really do not know ABAP much and never heard the term Wrapper FM that you were talking about:

it would be better if you could paste here sample code for the vendor number: lifnr

Thanks,

Ravi
