Function parameter has no return parameter

[Former Member]

Hi all,

I am creating a BAPI and connecting it using a Java servlet to display vendor details on accepting vender number.

I followed following steps:

1) defined a simple structure called ZBAPIVEND

2) wrote a function module: ZBAPIVENDFUN

3) adding API method: ZBAPI_VEND (error)

while adding an API it gives me following errors:

Error one:

"BAPI ZBAPIVENDFUN: the ref. structure LFA1 of parameter does not begin with BAPI"

---now I am pulling LIFTNR from LFA1 table, if cant remane LFA1 to BAPILFA1 in the function module coz BAPILFA1 does not exist. how do i solve this error?

Error 2:

"BAPI &1: BAPI function module &2 has no return parameter"

---infact i have used return parameter as BAPIRET2. still it gives me these errors.

Please help.

My code:

FUNCTION ZBAPIVENDFUN.

*"----

---

""Local interface:

*" IMPORTING

*" VALUE(LIFNR) LIKE LFA1-LIFNR

*" EXPORTING

*" VALUE(EXPORT) LIKE BAPIRET2 STRUCTURE BAPIRET2

*" TABLES

*" ITAB STRUCTURE ZBAPIVEND OPTIONAL

*"----

---

SELECT LIFNR NAME1 ORT01 ORT02 PFACH TELF1 TELFX FROM LFA1 INTO TABLE

ITAB WHERE LIFNR = LIFNR.

ENDFUNCTION.

While creating a BAPI API thats a mandatory thing to have the parameters start from BAPI.

Hope this helps

Hi VJ,

I am using the following slides to create it:

http://www.sapgenie.com/sapgenie/docs/BAPI%20JCO.pdf

Please go thro them quickly and let me know if they are correct. Coz the LFA1 table i have to access it as it is. Do i have to create one more table called ZBAPILAF1 and copy all the data from LAF1.

Thanks,

Apurv.

Hey VJ,

Thanks for the helpful answers. I have solved the problem. Using BAPIRETURN instead of BAPIRET2 solved it.

Thanks,

Hi Apurv,

95% of the cases you will have a BAPIXXXXX structure in your system. You can reuse them. I have created many BAPIS and in many cases i have found a reuasable structure in the Data dictionary.

Check se12 you should find one which closely matches your requirement. If you dont find one then you will have to create a new one.
