There are in fact three types of production process that can be executed in SAP. They are :
3. Production – Process Industries.
The configuration settings related to Discrete Manufacturing and essential Repetitive manufacturing is discussed in detail here.
First, it is good to 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.
Here, I believe you have got an idea about the steps involved prior to the production execution process. Next, let’s discuss about the production execution process now.
The SAP 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 :
a) Material availability
b) Capacity availability
c) Creation of Batch
d) 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 in the 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
a) Through confirmation.
b) 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 in the Production scheduling profile and order type parameter.
Now, you will easily understand What is Backflushing?
It is the process of issuing components automatically while confirming the production or process order.
Hope the above briefing and explanation has given you the enough idea to go ahead for the configuration of the production execution process.
