Question

Hello Experts,
I am new to BAPI creation, my requirment has two decimal inputs(as import parameters) and out output can be a simple add of these two numbers.
Decimal Input has 9 characters with 7 decimals Ex: 10.0000000. How to create a structure or data type and use the same back in my BAPI.
What is the ABAP code that, I should write to add these two inputs and export them.
Please help ASAP, I am in a critcal position.
Thanks,

Hello Suma,
This error is caused because you are trying to use a data type rather a data element, it better if you follow the below process
Start with creating a Structure with ZBAPI name, from SE11
give a component name with Z and component type with Z and then double click on new component type and this will ask what to generate click on dataelement and enter discription then enter a Z new name in the Domain and double click on it, click on data type and enter DEC, no char 9 and decimal 7 then save activate, clikc on back save activate and again click on back and save activate now your sturcture will be saved. Follow the proces if have new data type or else the same for your next entres.
For your Req....
take component ZINPUT1 compenent type ZINPUT with domain as ZZINPUT...
use the sam for ZINPUT2 and ZOUTPUT and then save activate. Now the structure is created.
SE37 create new BAPI, In import parameters take parameters as T_INPUT1 and T_INPUT2 with ZBAPI_SUM-ZINPUT1 and ZBAPI_SUM-ZINPUT2.Then in export  if you wnat inputs also in there just give some export names and give the assoated type as what you have used in import, also add OUTPUT and RETURN with ZBAPI_SUM-ZOUTPUT and BAPIRETURN.Now write the source code as follows
FUNCTION ZBAPI_TESTDEC1.
""Local Interface:
*"  IMPORTING
*"     VALUE(T_INPUT1) TYPE  ZBAPI_SUM-ZINPUT OPTIONAL
*"     VALUE(T_INPUT2) TYPE  ZBAPI_SUM-ZINPUT1 OPTIONAL
*"  EXPORTING
*"     VALUE(INPUT1) TYPE  ZBAPI_SUM-ZINPUT
*"     VALUE(INPUT2) TYPE  ZBAPI_SUM-ZINPUT1
*"     VALUE(OUTPUT) TYPE  ZBAPI_SUM-ZOUTPUT
*"     VALUE(RETURN) TYPE  BAPIRETURN
INPUT1 = T_INPUT1.
INPUT2 = T_INPUT2.
OUTPUT = T_INPUT1 + T_INPUT2.
ENDFUNCTION.
Now save it and then activate and then clikc on tables tab then functional module on main menu and then relase.
Go to T-code SWO1 create new Obj with ZBAPI name and then clikc create enter Obj name,Name,Des,Program,and Application has to be * then enter.
Click on methods,Utilites, API Methods, Add method, Select BAPI Name then contine for 3 times then click BAPI Added in the methods then on edit change relase status- object type To modeled, To impimented and To relased at 3 diff times then follow the same for Object Type component.
Now click on red and white round button which is similar to BMW symbol. This will generate the BAPI and now you see it in BAPI T-Code.
Hope this helps you ...
Reward if helpfull....
