How to reduce downtime for setup table

Question

Scenario u2013According to system data, Setup table will normally take 5 days to fill but client agreed only for max 2 days downtime. User can do change only last 3 month documents not before that. For filling 3 month data in set up table 1 day required so I have to mange options accordingly.
Datasource u2013 2LIS_13_VDITM -> DSO u2013 ZBIllIG ->Info cube
I have to Reduce Downtime for Setup table so planning following optionsu2013
1.     First run the info package for Initialization without data transfer. Then start filling setup table without blocking the User. In case Users changes any document at the time of filling setup table then these changes will move to delta queue. Once setup table filled then execute full repair request and then Delta info package.
2.     Early delta initialization u2013 no idea how to perform steps.
Please share your views with detail steps.
OLI*BW doesnu2019t have any date range in selection criteria so manually I will find out document for particular dates and use these document range.
Checked lot of post in SDN but still expecting final answer to go ahead in Production.

Hi ,
Your requirement is Billing ODS and Cube - Reset up in R/3 SYSTEM & Initialization in BW SYSTEM .
Before starting find the previous data load volume and size.
1.Go to LBWG application value=13 (Always Schedule the job in the back-ground mode)
2.Verify using tcode u2018SE16u2019 that there are NO records in u2018MC13VD0ITMSETUPu2019 table after above delete job is complete.
3.Suspend the process chain job in BW.This is to avoid it getting kicked off while the reload process is still in progress.
4.Need to check LBWQ in R/3 system for MCEX13, unprocessed Outbound queue (records). This should be empty as the last delta would have processed all.
5.Delete the initflag in BW.
6.Need to check RSA7 in R/3 SYSTEM to verify that there is NO record for 2LIS_13_VDITM    (to be done right before the Setup job).
7.Create New Info Package for Info Source '2LIS_13_VDITM' for u2018Initialize without Data Transfer Optionu2019 .Execute the package.Re-establish the Delta processing flags in R/3 and BW for the Billing TD load .
8.Save the record count for table u2018VBRPu2019 using SE16 right before the setup job.
9.Schedule Billing Data Setup Job 'OLI9BW'  in R/3 SYSTEM .
10.After the Billing Setup job is complete in R/3 system, get the record count of table u2018VBRPu2019 again using u2018SE16u2019
Expeted time in R/3:5 to 7 hrs(setupjobs)
Expeted time for init and fullload : 6 hrs
ODS activation : 3hrs
Cube and with agrregates fill all : 8hrs.
