What are V1 & V2 updates within the SAP LUW? Why & How they
occur?
Answer / vijayanand poreddy
An update is divided into different modules (see also
Update Request). Each module corresponds to an update
function module.
There are two types of module.
The SAP System makes a distinction between primary, time-
critical (V1) and secondary, non-time-critical (V2) update
modules. The system also supports collective runs for
function modules that are used on a regular basis.
This distinction allows the system to process critical
database changes before less critical changes.
V1 modules describe critical or primary changes; these
affect objects that have a controlling function in the SAP
System, for example order creation or changes to material
stock.
V2 modules describe less critical secondary changes. These
are pure statistical updates, for example, such as result
calculations.
The V1 modules are processed consecutively in a single
update work process on the same application server. This
means that they belong to the same database LUW and can be
reversed. Furthermore, V1 updates are carried out under the
SAP locks of the transaction that creates the update (see
The SAP Lock Concept). This ensures that the data remains
consistent; simultaneous changes to the objects to be
updated are not possible.
All V2 updates are carried out in a separate LUW and not
under the locks of the transaction that creates them. If
your SAP System contains a work process for V2 updates,
these are only carried out in this work process. If this is
not the case, the V2 components are processed by a V1
update process.
All V1 modules of an update must be processed before the V2
modules.
