use BAPI CHANGE no effect in database

[Former Member]

Hi,

I develop web dynpro application to modify student data. I use this BAPI :

BAPI_STUDENT_CHANGE3 and BAPI_TRANSACTION_COMMIT.

The return message of BAPI_STUDENT_CHANGE3 is :

"Instance 0150000201 of object type Student has been change."

But there is no modification in the database !

Why ?

Can you help me ?

Best regards,

Mathieu

Here is my code :

//@@begin ExecuteSaveData()

Bapi_Student_Change3_Input inputStudentChange =

new Bapi_Student_Change3_Input();

wdContext.nodeBapi_Student_Change3_Input().bind(inputStudentChange);

Bapi_Transaction_Commit_Input commit =

new Bapi_Transaction_Commit_Input();

wdContext.nodeBapi_Transaction_Commit_Input().bind(commit);

String lastName =

wdContext.currentEt_Students_Student_SearchElement().getNachn();

String firstName =

wdContext.currentEt_Students_Student_SearchElement().getVorna();

String middleName =

wdContext.currentEt_Students_Student_SearchElement().getMidnm();

Date birthDate =

wdContext.currentEt_Students_Student_SearchElement().getGbdat();

String objectID =

wdContext.currentEt_Students_Student_SearchElement().getObjid();

wdContext.currentBapi_Student_Change3_InputElement().setObjectid(

objectID);

Bapistudent_Personal model = new Bapistudent_Personal();

model.setLast_Name(lastName);

model.setFirst_Name(firstName);

model.setMiddle_Name(middleName);

model.setDate_Birth(birthDate);

wdContext.nodeStudentpersonaldata_Student_Change().bind(model);

Bapistudent_Personalx modelX = new Bapistudent_Personalx();

modelX.setLast_Name(true);

modelX.setFirst_Name(true);

modelX.setMiddle_Name(true);

modelX.setDate_Birth(true);

wdContext.nodeStudentpersonaldatax_Student_Change().bind(modelX);

try {

// Calls remote function module ExecuteStudentSearch

wdContext

.currentBapi_Student_Change3_InputElement()

.modelObject()

.execute();

wdContext

.currentBapi_Transaction_Commit_InputElement()

.modelObject()

.execute();

} catch (Exception ex) {

// If an exception is thrown, then the stack trace will be printed

ex.printStackTrace();

}

Hi,

Bapi_Student_Change3_Input inputStudentChange =

new Bapi_Student_Change3_Input();

wdContext.nodeBapi_Student_Change3_Input().bind(inputStudentChange);

Why don not do like this.

inputStudentChange.setlastName(wdContext.currentEt_Students_Student_SearchElement().getNachn());

inputStudentChange.setFirstName(wdContext.currentEt_Students_Student_SearchElement().getVorna());

inputStudentChange.setmiddleName(wdContext.currentEt_Students_Student_SearchElement().getMidnm());

inputStudentChange.setbirthDate(wdContext.currentEt_Students_Student_SearchElement().getGbdat());

inputStudentChange.setObject(

wdContext.currentEt_Students_Student_SearchElement().getObjid());

The same thing commint BAPI also

Try like this it might helps you.

Thanks,

Lohi.

Hi Lohitha,

Thanks for your help. My solution was :

.....

Bapistudent_Personal data = new Bapistudent_Personal() ;

data.setLast_Name(lastName);

data.setFirst_Name(firstName);

data.setMiddle_Name(middleName);

data.setDate_Birth(birthDate);

inputStudentChange.setStudentpersonaldata(data) ;

Bapistudent_Personalx datax = new Bapistudent_Personalx() ;

.....

Regards,

Mathieu
