Hello Guys,
This document is basically for those who are new in SAP PP module.
We have so far seen the Master data and production
planning steps in PP. In this document we will go thru
the nuts and bolts of Production Execution. Alright lets
breeze through this.
There are three types of production process in SAP.
1. Discrete Manufacturing
2. Repetitive Manufacturing
3. Production – Process Industries.
Configuration settings related to Discrete Manufacturing and
essential Repetitive manufacturing is discussed in detail here.
First let us understand what is happening in the system prior
to the production execution process.
a. Planning quantities are derived and maintained in
the system.
b. Material Requirement Planning run will generate
the planned order for the net required quantity with
the start date of the production process
c. Master data (BOM and Routing details) will be
copied in to the planned order automatically during
MRP run.
Guys, I believe you got an idea about the steps involved prior
to the production execution process. OK, let’s discuss about
the production execution process now.
Production Execution process contains five important steps.
They are
1. Converting planned order to production order
2. Releasing the production order
3. Goods Issue for production order
4. Confirmation of production order
5. Goods Receipt against production order
1. Converting planned order to production order:-
Planned order has to be converted to production order to
account the entire production.
Production order or process order type has to be
mentioned when converting the planned order. Entire
master data will be copied to the respective order when
converting the planned order.
Order type is the most important configuration setting for
production execution.
2. Releasing the production order:-
Release of production order is an important step in
production order. Releasing of production order indicates
the commencement of production. Unless the order is
released, further processing of order is not possible.
While releasing the production order system can perform
1 Material availability
2 Capacity availability
3 Creation of Batch
4 Reservation creation
Configuration settings related to the above functions are
covered in Availability check, order type parameters.
3. Goods Issue for production order:-
Goods issue covers issuing required components to make
the finished product to a production order. While making
the goods issue, the document number can be updated in
the production order.
Configuration setting related to this is discussed in order
type parameter.
Goods issue can be made in parallel during confirmation
of operation. Relevant configuration settings related to
goods issue during confirmation are discussed in
confirmation parameter.
4. Confirmation of production order:-
Reporting of usage of components and activities are
termed as confirmation.
Confirmation to the each operation will be executed
according to the control key attached with each
operation.
Confirmation configuration setting controls
Adhering to the sequence of operation
Under delivery / over delivery tolerance
Back-flush components
Proposal and calculation of activity standard value
Above configuration settings are discussed in
confirmation parameter.
5. Goods Receipt against production order:-
Once the production is completed, finished products will
be received from the production order into the respective
storage area.
This can be achieved through two ways
1. Through confirmation
2. Through separate transaction.
Document number will be generated for each goods
receipt. This document number can be updated in the
production or process order.
Configuration settings related to these are discussed in
Production scheduling profile and order type parameter.
Now you will easily understand what is backflush? It is the
process of issuing components automatically while confirming
the production or process order.
Hope the above briefing has given you the enough idea to go
ahead for configuration of production execution process.
Best Regards,
Dheeraj Rawal
