Delta Update Problem when loading to Cube

Question

Dear all.
Scenario:
DataSources 2LIS_18_NOTIF and 2LIS_18_I0TASK are extracted to ODS Daily which is a Delta Update.Weekly once they are updated to cube which is also Delta Update.This is automated by a process chain.
DataSource 2LIS_18_NOTIF failed on 27.07.2005 which we did not notice.Datasource 2LIS_18_IOTASK is fine.I did a repeat delta for 2LIS_18_NOTIF which is successful.Data upto ODS is fine.
Now the problem is loading data from ODS to cube which is Delta Update to be loaded every week.There are some Update rules written in which <b>sy-datum</b> is used.
Proposed Solution:
Change sy-datum for every monday date and do the delta update for 7 2LIS_18_I0TASK requests and 1  2LIS_18_NOTIF request.Delete the request from Cube,to remove delta management for 2LIS_18_NOTIF request.Now load for second week with 7 2LIS_18_I0TASK requests and the same 2LIS_18_NOTIF.Do this for all weeks and finally reconstruct all the requests which are deleted from cube.
if i follow the above approach can there be any Data inconsistency?
please help me to resolve this issue.
Regards
Ravi.

Hi Ravi,
If you are going to make a code change, which it looks like you are going to do, then I would suggest the following:
- Create an InfoObject called ZMondayd. Define is a type date, and allow master data.
- Input in the date you want your update rules to use
- In the update rule, change the code to read the value from the InfoObject, not sy-datum.
- Load your data.
I would also set up a process to update the InfoObject on a weekly basis to hold the date that you want. By using this method, if for some reason or another this process fails, you do not have to make any code changes, just maintain the InfoObject with the correct date, and reload the data.
