Hey Arun,

I think you should refer to the same link referred by Jyothi.

Linkactive() : Such method is executed whenever a user moves to another record in the master table that gives an update to all linked data sources.

Next() : Moves focus to the next record in the data source.

Print() : Prints the current record.

Create() : Creates a new record in the data source.

ValidateWrite() : Determines whether data is valid and ready to be written.

Regards,

Geetika

int next()
{
    return Salestable_ds.next();
}

// This will move the focus to the next record in your datasource.


```
Validatewrite()
```

```
// used to  check and validate data
```

```
I am using to check mandatory field for address AccountNum

public boolean validateWrite()
{
boolean ret;
;
if(this.Address != "")
ret = super();
else
warning(" Please fill the address value");
return ret;
}

```

I believe your field Rno is not of type string. In such case(integer) you should write the condition as if(!Atna_Mark.Rno)

If you want error and you dont want it to be written to the database in case if the field is not filled , then It should be like this in your validateWrite method

if(!Atna_Mark.Rno)

ret = checkFailed(strfmt(" Please fill the address value"));
