Synchronisation
Everything that is changed in SAP S/4HANA is immediately reflected
as a change in the RAPID production planning cockpit and vice versa:
Everything that is changed in the PPC is reflected on the SAP
S/4HANA side.
The role of the database in SAP ERP is fulfilled by the live cache
in embedded PP/DS: The live cache can be updated both by simulation
and by making persistent changes that will be visible when
re-entering and as well to other users.
Synchronisation also has two main points:
Simulated changes:
From the PPC, SAP functions can be called up in a simulated mode
(for example, production order maintenance). Here from either side
(PPC or S/4HANA) changes can be made in planning, which are
reflected in the PPC or S/4HANA in simulation mode without the need
to save in both.
Persistent changes in the live cache:
All simulated changes can be saved in the RAPID planning cockpit
"PPC". All changes made directly in the PPC user interfaces or by
PPC algorithms, as well as all changes made by jumping to S/4HANA
functions, are saved persistently to the live cache.
Master Data
S/4HANA with embedded PP/DS has a reservoir of flexible master data
for production planning, which is also fully used by PPC: both for
creating and maintaining the most important transaction data in PPC
(planned orders/production orders) as well as their parameters for
planning purposes.
In embedded PP/DS master data is mirrored, i.e. the data exists on
the S/4HANA side as well as for PP/DS (transformation from one side
to the other is analogous to the CIF in APO). The PPC always
accesses the PP/DS master data, for example:
Product master
for example, lot-sizing parameters, planning strategies and ATP
fields
Product data structure
-
Input and output: Which products are manufactured and which
components are required
-
Production sequence of operations when determining alternative
resources, buffer time and overlap settings for
scheduling/simulation in PPC
Resource
Parameters for scheduling and executing simulations in PPC
Source of supply ID (analogous to production version)
Consideration of the sources of supply when creating new planned
orders in PPC
PPC Master Data
In addition to the master data in SAP S/4HANA with embedded PP/DS,
you can create your own master data in the PPC in order to achieve
certain planning functionalities that cannot be mapped with this
flexibility using just SAP PP/DS master data. These data always have
a direct reference to existing PP/DS master data (for example,
product master, resource, product data structure).
These include:
- Referencing a resource to a PPC resource
- Grouping of resources into resource groups and hierarchies
-
Feasibility matrix: determination of alternative resources per
operation (alternative mode)
-
Maintenance of product allocations according to available
capacities
