Transacation V_V2 is timing out

Question

When attempting to run V_V2 Rescheduling Deliveries for Backorder
management the report times out and a Time Out message is received.I am
attaching the short dump below with this? Please advise on the soluiton and
if this is a basis related issue or not? The dump also mentions about increasing the parameter
"rdisp/max_wprun_time". The current setting is 600 seconds.
Runtime Errors         TIME_OUT
What happened?
The program "SAPLV05L" has exceeded the maximum permitted runtime without
interruption and has therefore been terminated.
Error analysis
After a specific time, the program is terminated to make the work area
available to other users who may be waiting.
This is to prevent a work area being blocked unnecessarily long by, for
example:
- Endless loops (DO, WHILE, ...),
- Database accesses with a large result set
- Database accesses without a suitable index (full table scan)
The maximum runtime of a program is limited by the system profile
parameter "rdisp/max_wprun_time". The current setting is 600 seconds. If this
time limit is
exceeded, the system attempts to cancel any running SQL statement or
signals the ABAP processor to stop the running program. Then the system
waits another 60 seconds maximum. If the program is then still active,
the work process is restarted.
How to correct the error
Programs with long runtime should generally be started as background
jobs. If this is not possible, you can increase the system profile
parameter "rdisp/max_wprun_time".
Depending on the cause of the error, you may have to take one of the
following measures:
- Endless loop: Correct program;
- Dataset resulting from database access is too large:
Instead of "SELECT * ... ENDSELECT", use "SELECT * INTO internal table
(for example);
- Database has unsuitable index: Check index generation.
If the error occures in a non-modified SAP program, you may be able to
find an interim solution in an SAP Note.
If you have access to SAP Notes, carry out a search with the following
keywords:
"TIME_OUT" " "
"SAPLV05L" or "LV05LU01"
"WERTE_ERMITTELN"

Answer 1

Increase the value of parameter "rdisp/max_wprun_time" in RZ10 or RZ11 t-code and try again.
