LO data loads (DELTA)

Hello,

I have gotten to the point of switching on the V3 and running Delta loads for LO data.

My question is this:

What happens when you have a Delta load that gets interrupted? For example lets say I have a process chain and when it begins loading data from VAITM, the transfer is interupted and thus fails.

How would I recover from a situation like that so I don't end up missing, losing, and in attempt to correct duplicating data?

Also what would happen on the R/3 side, say I have the V3 updates scheduled hourly. What would happen if the R/3 system was rebooted in the middle of an update or something similar?

Thanks,

Nick

    Usually this situation occurs if suddenly the connection between R/3 and BW Breaks. In this case you just restart the delta processs again and you won't loose any data.

    Before reboot the R/3 system they inform BW team so that we stop V3 Jobs and when Reboot is completed we need to start the V3 Jobs.

    Hope this helps

      Nick,

      i want to ADD few points to abouve lines. when ever you request delta from BW, once if it is success(Green) it will send confirmation to the R/3 System. then these time stamps, Request number(delta load request) will saved in one R/3 Table. if any reason, r/3 system didn't get any response, R/3 system will think, still process is going on. this is happend for delta1. delta records will cleared from delta queue for delta1 records after the next delta success. you can ensure that, data is consistent and doesn't effect.

    Hi Nick,

    if the process is interrupted between transfer from R/3 to BW generally the system R/3 doesn't receive the commit and so you can launch IP for delta without loosing data.

    if R/3 system crash during data transfer I think you will loose delta, so you have to re-init the whole process.

    Ciao.

    Riccardo.
