This is another cool nice feature
in SAP BW 7.3. Sometimes DTP load
fails with one off error messages like RFC connection error, missing packets,
database connection issues etc. Usually these are
resolved by repeating the failed DTP load.
In BW 7.3 there is an option
under execute tab which if you check will automatically repeat red requests in process
chains. I think this is a cool feature and saves us time and effort in
monitoring data loads.
Below
is F1 help on this option.
Automatically Repeat Red Requests in Process Chains
If a data transfer
process (DTP) has produced a request containing errors during the previous run
of a periodically scheduled process chain, this indicator is evaluated the next
time the process chain is started.
If the indicator
is set, the previous request that contains errors is automatically deleted and
a new one is started.
If the indicator
is not set, the DTP terminates and an error message appears explaining that no
new request can be started until the previous request is either repaired or
deleted.
Use
If you set the indicator, you
reduce the administrative effort for process chains. Terminated process chains
can repair themselves.
Dependencies
Note that if a delta update
is carried out, the repaired request contains not only the data of the
terminated request, but all data that has been added to the source since then.
This can lead to both performance and consistency problems.
Example of a Consistency Problem:
A transfer that has the
prerequisite that the data of only one day is transferred at a time, and that
produces incorrect results, leads to consistency problems if, during the
repair, the data of more than one day is to be transported at the same time.
