WM: Enhancements to the PP-Interface


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:
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).
b) Evaluation of the production orders from the WM view ( RLWMPPC4):
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:

You define the following new parameters in the production view:

You define the following new parameters in the warehouse management view at the warehouse number level:

You define the following new parameters in the warehouse management view at the storage type level:

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.
