Hi Nutan,

if I understand you, then you have a simple validation. Therefore you can use the validation functionality of VC for your components. An alternative could be by writing a new ABAP RFC function module like:

BAPI Input parameters as input and BAPI output parameters as output and an additional return code or string for a message:

IF I_FIELD IS INITIAL.

E_RETURN_CODE = "THE FIELD IS EMPTY."

ELSE.

CALL FUNCTION <YOUR_BAPI>

<BAPI PARAMETERS>

ENDIF.

I hope that helps.

Hi Marcel,

Thanks for your reply.If I am not using the New Bapi as you have mentioned then how can use the case in VC.

Example:

Bool(If(@RoleCd=="",'Enter the Code', HERE I WANT TO CALL THE BAPI FOR FALSE CONDITION)

How to get this?How can I give the event name in the false exp?Is it necessary to use the New Bapi as you have mentioned.If not then please help me out in VC itself?

Hi Nutan,

I think you have to enter a value into an input field and then click on a button.

So you can add a formula so that the button is disabled if the input field is empty, e.g. ISNULL(@filed) or the user can click on the button and a guard condition decides which of the two action will be done.

E.g. ISNULL(@filed) for showing the error message in a plaintext (passing the message to a data store and the plaintext field refers to the data store value) and !ISNULL(@field) for passing the data to the BAPI.

Hi Nutan,

How are you populating your field? By query, BAPI...
