Web Dynpro with BAPI

[Former Member]

Hi everyone,

I am trying to learn Web Dynpro, can you please give me a good example of how to create a Web Dynpro application using a BAPI. let's say a BAPI to display the customer records, for example the user should be able to enter the customer number and get his details.

Any help will be appreciated.

Thanks,

Rajat

Thanks for the reply Rich I followed the tutorial and created the web application and everything looked perfect except when I am entering the from and to City details and clicking on get flight details button I am not getting any result. Can you please help me in this.

Thanks,

Make sure that the values that you are entering are valid in the DB.

Thanks for the quick reply Rich... I just looked the table that we are using in the BAPI and found that there is noithing in there.

[RichHeilman]

In that case, you need to generate some data in the flight model database. Use program SAPBC_DATA_GENERATOR to generate this data. Once that is done, re-run your WD application, and it should work.

Thanks for the reply Rich, I created couple of more web applications !! one for displaying the vendor details, i.e. enter the vendor number and you will get the details, and this one is working fine. Now i tried to create an application for displaying the invoice header details by entering the document number using BAPI "BAPI_INCOMINGINVOICE_GETDETAIL". but when I test it i get the screen where i Need to enter the invoice number, as soon as I enter the Invoice numbr and hit enter I am getting following errors.

The following error text was processed in the system RS2 : Incorrect parameter with CALL FUNCTION.

The termination type was: RABAX_STATE

The ABAP call stack was:

Check transaction ST22 for corresponding ABAP dump. This should tell you what the issue is.

Hi Rich,

I already did it and I found that I have commented Return parameter while calling the BAPI, Ijust uncommented that and I am getting this error now "RETURN" is not an internal table. I am looking into this.

Thanks,

Hi Rich,

I uncommented the retrun parameter but now I am getting this error:

"RETURN" is not an internal table "OCCURS n" specification is missing.

In the attributes I have declared this Attribute as:

Return with associated type BAPIRET2.

can you please see what am I doing wrong.

[RichHeilman]

the return parameter should be type as an internal table. Basic ABAP skills are required to complete these tutorials successfully.

data: bapi_return type table of BAPIRET2.

Hi Rich,

I have already tried doing this and I m still gettig the same message:

That's how my code looks like:

DATA: return type table of BAPIRET2.

CALL FUNCTION 'BAPI_INCOMINGINVOICE_GETDETAIL'

EXPORTING

INVOICEDOCNUMBER = LV_INVOICEDOCNUMBER

FISCALYEAR = LV_FISCALYEAR

IMPORTING

HEADERDATA = LS_C_HEADERDATA

ADDRESSDATA = LS_C_ADDRESSDATA

TABLES

ITEMDATA = LT_C_ITEMDATA

" accountingdata =

" glaccountdata =

" materialdata =

" taxdata =

" withtaxdata =

" vendoritemsplitdata =

RETURN = WD_THIS->RETURN

" extensionout =

and when I double clicked on the "RETURN" its taking me to the attribute section, where Attribute "Return" has been declared as Ref to BAPIRET2

[RichHeilman]

Yes, try it without the WD_THIS reference, and add a period at the end of it.

DATA: return type table of BAPIRET2.
CALL FUNCTION 'BAPI_INCOMINGINVOICE_GETDETAIL'
EXPORTING
INVOICEDOCNUMBER = LV_INVOICEDOCNUMBER
FISCALYEAR = LV_FISCALYEAR
IMPORTING
HEADERDATA = LS_C_HEADERDATA
ADDRESSDATA = LS_C_ADDRESSDATA
TABLES
ITEMDATA = LT_C_ITEMDATA
" accountingdata =
" glaccountdata =
" materialdata =
" taxdata =
" withtaxdata =
" vendoritemsplitdata =
RETURN = RETURN.  "<---  just use RETURN here, and add a period 
" extensionout =
