A Beginner's Guide To PI sheets

 

Introduction:

 

PI Sheets in general can be used to describe the total production process or a part of it. The PI sheet is
used to inform the process operator about the individual production steps that need to be performed.
Apart from control information, the PI sheet can contain input fields and pushbuttons. You can, for
example, define fields into which you want the process operator to enter the quantity of
material components consumed for a phase. The material withdrawals must then be posted as goods
issues in inventory management. You can use process messages to automatically carry out this function.
In General there are two types of PI sheets in Normal SAP
  1. ABAP based PI sheets
  2. Browser based PI sheets

 

  We shall concentrate on the later version that is browser based PI sheets 

1 Master Data:

  
  1. Material Master
  2. BOM
  3. Master Recipe.
     

2 Configuration Requirements

  In the initial step transport all the predefined characteristics, message categories
and display variants predefined by SAP from the reference client to our logon client.
 
  1. SPRO-->Production planning for Processindustries-->Process management-->Standard settingsSAP1.jpg

  

Here transport all the standard settings to your local client. 

3 Control Recipes and Control Recipe Destinations

  Control recipes are used to transfer the control data defined in the process order by
the user to the process control. The control data like process instructions
assigned to the phase are transferred to their respective destinations assigned
in the phase.
Control Recipe Destinations:  SAP standard has Four types of recipe destinations defined 
  1. Transfer to ABAP list based PI sheet
  2. Download to ext. system, initiated by
    SAP process management
  3. Download to ext. system, initiated by
    ext. process control
  4. Transfer to browser-based PI sheet

Path: SPRO-->Production planning for Processindustries-->Process managementà-->Decentralized Process Management

     -->Define and Set Up Control Recipe Destinations

Here in the work area enter the plant and select enter. Now double click the HTML-PI sheet (05) to open it.
Here it has the destination type 4 which will enable to create browser based PI sheets. In the destinations
we can assign digital signatures for the process steps.  Here we can have levels of approvals defined for the process step. 

4 Process Message Characteristics

  There are standard process message characteristics available in SAP which can be transported to the local client.
All standard characteristics for process messages starts with ‘PPPI’ and cannot be changed. If we require additional
characteristics then user can create them as per the business requirement.
Path: SPRO-->Production planning for Processindustries-->Process management--> Process Messages
-->Define Characteristics forProcess Messages
 
Process Messages and Destinations:  Process Messages are used to transfer the process data from process control to the
defined destinations.
  Process messages trigger various business functions such as GI, GR, mail trigger, data
transfer to external system etc.
  The actual data entered in the system are transferred to the respective work areas defined
in the destinations.
  The process message categories contains the process instruction characteristics, message
destinations and the characteristics which the destination needs to update.
  Standard SAP contains several Process messages
which can be transported to the local client; in addition we can create new messages with destinations as per the business need. 
Path: SPRO-->Production planning for Process industries-->Process management--> Process Messages-->
Define and Set Up Process Message Categories
SAP3.jpg
  The message categories will have process instruction characteristics assigned
sap4.jpg
Each Message will have destinations with their respective address assigned
SAP5.jpg
We can create multiple destinations in a single message category. 
Now each destination needs to be assigned characteristics to update the target
fields

5 Assigning Process Instructions to Master Recipe

  Open the master recipe in change mode and go to operations header screen. Here we can assign the activities which needs to be carried out through PI
sheets to eachphase as per the business requirement.
SAP7.jpg/servlet/JiveServlet/downloadImage/38-84701-214938/SAP.jpg
Select the phase for which you want to assign the instructions and click on Process Instructions.In the next screen assign the process instruction categories to the selected phase and click on simulate PI sheet.This will display the output format of the PI sheet if there is no error in the assignment
/servlet/JiveServlet/downloadImage/38-84701-214939/SAP.jpgSAP8.jpg
The simulation will not work if there is any error in the characteristics assigned.
After assigning successfully save the Master Recipe.

6 Releasing Control Recipes


Now create the process order as usual and once you release the order the ‘Generate Control Recipe’ indicator
gets enabled, click on this indicator to release the recipes and save the order.

Upon successful release of control recipes go to T code CO53 to convert the recipes to PI sheets
In the initial screen enter the order number and press ‘display’
SAP.jpg

In the next screen select the recipe and press -send,this action will generate PI sheets
SAP.jpg
 
Now go to T code CO60 and open the PI sheet which has been generated for this order
Here enter the plant, order number and execute(F8)
SAP.jpg
In the next screen select the PI sheet and press ‘maintain PI sheet’ This will open the PI sheet in Change mode

7 PI Sheets

We can have a wide array of instructions assigned for each phase.
Phase 0020 has the following assigned
  1. Standard operating Procedure – here we can enter
    the instructions which the user needs to do and check while performing
    operation 20. If DMS is integrated with PI sheet we can assign drawings and
    PDF  files if required
  2. The table is used to enter the GOODS ISSUE
    quantity for the order, this is just a sample configuration so we can have the
    material number assigned. The + mark at the bottom of the table allows to add
    multiple lines so that we can have partial GI’s and also to enter for multiple
    materials. This is enabled by using ‘Repeated Data Request’ in the instructions
  3. ‘GO TO MIGO’ tab allows the user to go directly
    to MIGO, likewise we can go to any transaction which is required, it is also
    possible to open a blank SAP screen.

Phase 0040 is used to record the temperature, data and time of the reading, this will be only for information and it
will not update any table records. This can be used in process industries where it is required to record a measured value
like temperature, pressure etc.

Each step can also be incorporated with ‘DigitalSignatures’. This will help track the data entry user and also the time
(Records of signature will be available in DSAL)
sap.jpg

Phase 0080 can be used to carry out GR for materials,here again we can add a wide array of instructions like batch, final delivery
etc.

Data required for phase wise confirmation, time ticket confirmation etc can all be incorporated in a PI sheet.

QM results recording can be carried in the same manner as above or can be done through a call transaction.

Once the user enters the values in PI sheets the data needs to be transferred so that it will update the order.

This can be done through T code CO54.

In CO54 enter the order number and press message list
sap.jpg
Here select the process messages and press send, the data will get transferred to their respective locations.

SAP.jpg
Now open the process order and check the goods movement carried out through PI sheets
SAP.jpg
This is just an overview document, apart from the above awide array of activities like time ticket, final delivery,
simple signature, digital signatures with authorization levels etc can be done through a PI sheet.
