For Release 4.0, several customer requests were taken into
consideration to enhance the WM interface to PP for the staging of
PP/PP-PI production orders. The following topics were
implemented:
1. Generation of complete
requirements :
When the system generates a transfer
requirement for a PP/PP-PI production order for pick parts, it must
contain all of the relevant components for the order. Frequently,
errors that occur during WM staging are passed over. This sometimes
results in the generation of an incomplete transfer requirement
without the knowledge of the user. For automatic WM staging, you
need to ensure that each transfer requirement created by the system
contains all components that are relevant for WM staging.
Now it is possible to make a setting
in Customizing that prevents the generation of incomplete transfer
orders. With this setting, the system will not create transfer
requirements unless it contains all relevant components.
Additionally, a message is entered in the log that references this
error.
Caution: This
completeness check does not refer to the entire production order,
instead, it refers only to the process concerned.
2. Switching Off Quantity Reduction
When Generating
transfer orders:
When the system generates transfer
orders for transfer requirements that were created for pick parts
during WM staging, as a rule, quantity reduction takes place if the
materials are supplied to a fixed production storage bin.
The determination of the available
quantity in the production storage bins affects system performance
significantly and takes place even if it is not necessary (for
example, when the requested quantity is staged in the exact amount
without overdeliveries).
Now it is possible for you to switch
off quantity reduction for each storage type separately.
3. Calculating the Available Quantity
for Quantity Reduction:
Previously, when the system
calculated the available quantity for quantity reduction, all open
reservations and transfer requirements were evaluated. This also
included the transfer requirements that were created manually
(those that were created without reference to a reservation). This
led to an incorrect calculation of the available quantity in the
production storage bin. The following changes were made for Release
4.0:
Transfer requirements that are created manully are not taken
into consideration.
All transfer requirements that refer to a production order are
taken into consideration. In these transfer requirements, items
that do not refer to open reservations (for example, TRs that refer
to deleted reservations or to a production order that has been
technically completed) are not taken into consideration.
4. Confirmation of Batches in Fixed
Storage Bins:
The return confirmation of batches
issued in WM for a production order can only take place for pick
parts. When dynamic production storage bins are used, this
confirmation takes place automatically since in this case the
system carries out the assignment of batches and production orders.
If pick parts are supplied to a fixed production storage bin that
was defined in the control cycle during WM staging, there is no
definitive assignment between the production order and the batches
that are found because such bins are used for several production
orders. In this case, if a notification is to take place, it be
explicitly configured as such in Customizing.
Caution: The confirmation of batches
is not supported for quantity reduction.
5. Complete Staging:
When generating transfer orders for
transfer requirements, you can prevent the system from creating an
incomplete transfer order. If one item (the total quantity of
material in a transfer requirement item) cannot be converted, the
system will not create a transfer order for the rest of the
items.
6. Take Confirmed Quantity in
Transfer Requirements into Consideration:
When you create transfer
requirements, as a default the required quantity of the components
is copied over as the requested quantity. Even when the material is
not available or is only partially available, the total required
quantity of the components is carried over into the transfer
requirement quantity. This could result in the creation of transfer
orders for production orders for which there are insufficient
materials available. On the other hand, materials may only be
partially supplied or not supplied at all for production orders for
which the available quantity was actually confirmed.
Now you can define in Customizing
that the confirmed quantity of a component is to be carried over as
the requested quantity.
Caution: This type
of staging has only been implemented for pick parts since these
parts are staged based on a production order.
7. Display of Material Text when
Staging Release Order Parts (Transaction LP12):
When you stage release order parts
using transaction LP12, you can display the list of the release
order parts together with the material texts.
8. Optimized Database Access to
Transfer Requirements During Quantity Reduction:
In Release 3.0, the system would
access transfer requirements for quantity reduction as a rule via
the
destination storage type index. Since this led to
performance problems for some combinations, as an alternative the
system can now access the transfer requirements via the material or
via a DATABASE-TABLE-JOIN. If performance problems occur during
quantity reduction, you can now change the access method.
9. Various Evaluation Reports:
a) Evaluation of the Production
Storage Bins per Storage Type ( RLWMPPC3):
This report provides an overview of
the production storage bins. A traffic light icon displays the
status of the respective storage bins depending on the stock
situation. This makes it possible to identify critical situations
more quickly. More detailed information is available in the report
documentation (RLWMPPC3).
This report evauluates PP orders from
the WM view. A traffic light icon displays critical situations that
result from discrepancies between reservations and the
corresponding transfer requirements. More detailed information is
available in the report documentation (RLWMPPC4).
c) Consistency Check for
Control Cycles ( RLWMPPC5):
This report checks the consistency of
the control cycles. In particular, the system checks to see whether
the staging in the control cycle is in agreement with the staging
in the reservation. A traffic light icon is used to display
critical situations. More detailed information is available in the
report documentation (RLWMPPC5).
10. Customer Exit for Automated TR
Generation:
When you use this enhancement, you
can automate the generation of transfer requirements during the WM
staging for production orders. More detailed information is
available in the report documentation (MWMPP001).
Change system parameters in customizing
The new control parameters need to be maintained in Customizing
under Define production.
The control data for the production interface in Customizing was
divided into two blocks:
Parameters that need to be maintained from the viewpoint of
Production.
Parameters that need to be maintained from the viewpoint of
Warehouse Management. These were further subdivided into controls
for the
warehouse number and type.
You define the following new parameters in the production
view:
Creating complete transfer requirements
Take confirmed quantity of the transfer requirement into
consideration
You define the following new parameters in the warehouse
management view at the warehouse number level:
Batch confirmation for fixed storage bins
Complete material staging
You define the following new parameters in the warehouse
management view at the storage type level:
Switch off quantity reduction during transfer order
generation
Database access to the transfer requirements during quantity
reduction
Changes to the interface
If the confirmed quantity is taken into consideration when
transfer requirements are created, the system displays this
quantity as the requested quantity in the staging list.
