nlapiYieldScript()
Creates a recovery point and then reschedules the script.
The newly rescheduled script has its governance units reset,
and is then placed at the back of the scheduled script queue.
To summarize, nlapiYieldScript works as follows:

nlapiYieldScript()は定期スクリプトの再スケジュールで使われます。
このAPIの実行で、
�@リカバリポイント作成
�A新しい定期スクリプトを起動
�B新しい定期スクリプトに�@を渡す

function runScheduledScript(status, queueid)
{
var records = nlapiSearchRecord('customer', 15);

for( var i = 0; i < records.length; i++ )
{
handleCustomer(records[i].getRecordType(), records[i].getId());

if( (i % 5) == 0 ) setRecoveryPoint(); //every 5 customers, we want to set a recovery point so that, in case of an unexpected server failure, we resume from the current "i" index instead of 0

checkGovernance();
}
}
/*********************************************************************************************************/
function setRecoveryPoint()
{
var state = nlapiSetRecoveryPoint(); //100 point governance
if( state.status == 'SUCCESS' ) return; //we successfully create a new recovery point
if( state.status == 'RESUME' ) //a recovery point was previously set, we are resuming due to some unforeseen error
{
nlapiLogExecution("ERROR", "Resuming script because of " + state.reason+". Size = "+ state.size);
handleScriptRecovery();
}
else if ( state.status == 'FAILURE' ) //we failed to create a new recovery point
{
nlapiLogExecution("ERROR","Failed to create recovery point. Reason = "+state.reason + " / Size = "+ state.size);
handleRecoveryFailure(state);
}
}

}

{

}
// state.status will never be SUCCESS because a success would imply a yield has occurred. The equivalent response would be yield
}
