Data Source Problem

Hi all,

We have a data source called 2LIS_18_I0NOTIF, which gets the data from R/3 to ODS on daily basis( Delta update).

On 19th Feb 2005 this data source got failed due to SYSTEM_NO_ROLL error in the source system(R/3).

We know that the above error has come due to insufficient memory space.

So we approached basis team to increase the memory size if possible.

But increasing the memory size is not possible they said.

So I thought of extracting the data from failed date(19th Feb) to till date(23rd Feb) thru full update using 0CALDAY as input parameter in the scheduler and later initialize the delta without data transfer. Will this approach work?.....

Please suggest with alternatives/suggestions.

many thanks

    Hi Venkat,

    to perform a full you need to fill related setup tables, but I believe this is a dangerous approach....first of all you need to stop your source system posting operations (related to your application component) and then fill your setup table with a consistent safety time interval (not only from 19th but before), otherwise you it will be possible that some record in your ODS still remain with only some delta changes and not other ones...then you have to overwrite anything with a full repair request, then delete your previous delta channel and reinit with no data...but, honestly, I suggest you to reinit your flow !

      unfortunately there is no second approach (all my previous post contains an explanation of method suggested by you)...if you are not able to assure a consistency to your full repair request (via setup), the only way to follow is to completely reinit your flow and start again...
