Difference between Process Message Categories and Process Instructions

[Former Member]

Hi,

I am trying to understand the difference between Process Message Categories (o13c) and Process Instructions (o12c) and there roles.

I understand that Process Instructions are specifically linked with control recipes but my confusion is to the role of process message categories.

Spoecifically there use in PI Sheets.

Can someone give me a brief distinction/explanation please

cheers all

Hello, put in a a simple way, process instructions are the information provided to operators or control system in a control recipe or PI Sheet. They are the tool to the link from SAP to Shop Floor . Examples are Component lists, phase activities, operative instructions, etc.

Process message consist of the information coming from Shop Floor to SAP. Information are amterial consumption or produced quantities, start and finish times in a phase, actual activities, process conditions (temperature, pressure, etc. )

In some cases, the process instruction contains a reference to a process messsage, which leads to the automatic generation of the process message in the PI Sheet.

Hope this helps-

For instance

Information from SAP to PI Sheet

Process Instruction CONS_1 (information about the component to be consumed)

10 PPPI_DATA_REQUEST_TYPE Simple data request

20 PPPI_MESSAGE_CATEGORY PI_CONS

30 PPPI_PROCESS_ORDER

40 PPPI_OPERATION

50 PPPI_PHASE

60 PPPI_MATERIAL

200 PPPI_AUTOMATIC_VALUE Event date

210 PPPI_AUTOMATIC_VALUE Event time

300 PPPI_INPUT_REQUEST Material quantity consumed:

301 PPPI_REQUESTED_VALUE PPPI_MATERIAL_CONSUMED

302 PPPI_UNIT_OF_MEASURE

Note that there is a reference to process message PI_CONS

Information from PI Sheet to SAP

Process Message PI_CONS (characteristics have been completed by the operator)

PPPI_BATCH Batch

PPPI_EVENT_DATE Date of event

PPPI_EVENT_TIME Date/time of event

PPPI_FINAL_ISSUE Indicator: final issue

PPPI_MATERIAL Material number

PPPI_MATERIAL_CONSUMED Quantity of consumed material

PPPI_OPERATION Operation number

PPPI_PHASE Phase number

PPPI_PROCESS_ORDER Process order

PPPI_RESERVATION Reservation

PPPI_RESERVATION_ITEM Item number of reservation

PPPI_SPECIAL_STOCK Special Stock Indicator

PPPI_STOCK_TYPE Stock type

PPPI_STORAGE_LOCATION Storage location

PPPI_UNIT_OF_MEASURE Unit of measure

PPPI_VENDOR Vendor

You can see in O13C the function module required to process the message and update the process order with the information about component withdrawal.

Hi

Process instructions are nothing but the process parameters(Characteristics) that need to be maintained in your process

Process instruction categories describes the information contained in the process parameters.

Really need a bit more....

For example (O13C) PPPI_PROCESS_ORDER is a characteristics of Process Msg cat PI_COMM.

(O12C) PPPI_PROCESS_ORDER is a characteristics of Process Instruction catergory CONF_PH how do the two relate ?

What purpose does the Process Msg cat provide ?

I guess this is my question and confusion
