hello,

I add new field in table the I want to initialize this field using chain of command in class extension,

I add code like this :

[ExtensionOf(classStr(OutLogisticOrderOut))]
 final class OutLogisticOrderOut_Extension
{
    public void createDetLOLine(Envelope _envelope, EnvLOOut _envLOOut, Warehouse _warehouse, ExchangeLineInfo _lineInfo)
    {
        Common                  sourceLine;
        DetLOLineOut            detLOLineOut;
        SalesLine               salesLine;
        sourceLine = this.retrieveSourceLine(_lineInfo);
        salesLine = sourceLine;
        detLOLineOut.PrepackGroupId = salesLine.Code;
        next createDetLOLine( _envelope,  _envLOOut,  _warehouse,  _lineInfo);
    }

}

the method createDetLOLine() : insert data in the table DetOLLine :

Hi BASMA,

It should be the before the next call. If you add the code after next your custom field doesn't get a value because record gets inserted into a table DetOLLine at line number 12.

Also don't create a new buffer for DetOLLineOut table. Use the buffer that is referred in the original method "createDetLOLine".

Thanks,

hello,

I get error When I delete the declaration of buffer :

public void createDetLOLine(Envelope _envelope, EnvLOOut _envLOOut, Warehouse _warehouse, ExchangeLineInfo _lineInfo) { Common sourceLine; SalesLine salesLine; sourceLine = this.retrieveSourceLine(_lineInfo); salesLine = sourceLine; detLOLineOut.PrepackGroupId = salesLine.Code; next createDetLOLine( _envelope, _envLOOut, _warehouse, _lineInfo); }

Error The qualifier 'detLOLineOut' is not valid for field 'PrepackGroupId'.

What is the buffer name for "DetLOLineOut" table declared inside the method createDetLoLine?

Just navigate to the method and see the buffer name for "DetLOLineOut".

Use the same buffer to initialize values to your custom field.

Thanks,

After adding the new field have you done build and synch?

Try doing build and synch of your model and check again.

Error says that field 'PrepackGroupId' is not available in table.

Thanks,

Check whether intelli sense is working - Just type the buffer name and see whether its showing any suggestion for that buffer.

If that doesn't work then try adding the logic on table level insert or initValue method before next keyword. But make sure you will have required values to assign it to your custom field.

Thanks,

Is the buffer 'detLOLineOut" is declared globally or declared inside the method 'createDetLoLine'?

I think its declared inside the method that's why you are getting the error.
