0HR_PT_1 Datasource doesnot extract New employees in Delta Load

Question

Hi Gurus,
I did an initialization of delta based on Company code selection and calendar month range (01.2008 to 12.2009) in the month of Aug-09 around 60million records came into BI.The dataload was successfull (Info yellow but made into green). After that when the new employees created in ECC for these emplyoees there is no data being extracted through 0HR_PT_1 datasource.
Gone through the following notes
Note 670751 - Time management extractors and new employees
This talks ablut selection range for Personnel Number which i have not given at the time of init. But now already data is there in BI and it will take hell out of time. Its not sure even though we did init selection with peronal Number ranges 10 years data is coming into BI.
Note 353177 - Long-run. progr. at time data extrct. in delta mode
This note talks about time frame which itself is a confict with the infotype 0439.
Please suggest how to minimize the successfull initialization of delta with out missing the new employees workschedule data.

Answer 1

If u click the 'Documentation' icon at the IMG node, u can see the following
Define Time Frame for Transfer
In this step, you define the time frame used to select time data for reports in the Business Warehouse. Only time data entered for a date or period within this time frame is transferred to BW.
The time frame you specify is activated when you
Request data for initializing the delta transfer
Request the delta since the last request or repeat the delta request
Transfer all requested data and do not restrict the required period in BW.
Example
1. You regularly use BW to gain an overview of the current calendar year.
You enter January 1, 2001 as the earliest transfer date and December 31, 2001 as the latest transfer date. At the start of the next year, you set the dates forward one year.
2. You want to have regular access to the current data. You also want to take account of time data that has changed in the last six months. You are also interested in absences that have been recorded for future periods.
You therefore set the earliest transfer data to six months ago and the latest transfer date to six months in the future. Each month, you set the dates forward one month.
Recommendation
Make the time frame as small as possible to avoid unnecessarily long runtimes, and as large as necessary to transfer all relevant data.
Activities
1. Choose the Check Feature TIMMO activity.
2. Check the modifiers specified. If you want to use special modifiers for BW, adjust the feature accordingly.
3. Choose the Earliest Transfer Date activity and enter the date up to which
a) Data is to be selected (when you request all data)
b) All changes made after the last request are to be selected (for a delta request)
4. Choose the Latest Transfer Date activity and enter the date up to which data entered for the future is to be selected.
5. Note these activities (outside the SAP system) for your periodical activities so that you can update the time frame monthly or annually, for example.
