How Are the PI Instruction Categories Assigned to Process Order

HI SAP PP-PI Experts,

I would like to know how Process Instruction Categories are getting selected and assigned to process orders without maintaining this in C202 (Master Recipe). I have checked our setting in the control recipe destination and it has PI Categories assigned but not all of these are assigned to process order when Control Recipe is created. May I know how that happens and where I can set this up?

Thank you!

Jay

    Hi,

    As correctly mentioned by Mr Sahil, Process Instruction Categories are assigned to CRD (Control Recipe Destination) which is set in master Recipe.

    Here's a brief snapshot:

    1. Define the Control Recipe Destination in O10C (with a Proper Control Recipe Destination Type (this decides where you shall use PI Sheet or External MES)

    2. Created or maintain the Process Instrctions in O12C for that specific plant . From your query above I assume that you know this

    3. Assign the Process Instructions to the CRD in O10C and use the Filter and Scope properly

    4. These IMG settings are then used in the Master Data - Master Recipe where for a specific Phase you use a Specific CRD (you have used MP). You may have multiple phases and multiple CRDs assigned to a single Recipe

    5. Process Order while creating the Control Recipe (which is a set of Process Instructions) checks the CRD for a specific Phase and generates the Process Instructions based on the Scope and Filters activated in O10C

    The reason you can't see all the Process Instructions assigned to CRD in your process Order is specifically due to the scope of generation and or the filters set (in O10C). Also the additional Process Instructions that you can see is there may be due to any Dynamic Functional Call type (06) Process Instruction being used in the O10C setting which might have called other Process Instruction (though this is difficult to confirm from these two screen shots you have attached). Also you can check the Process Order Status. If instead of CRCR it is something else (like X***) then I assume you might have the Xstep activated.

    Hope this helps

      Hi,

      I don't have any specific document for this. However, here is my 2 cents:

      1. Scope of Generation--> This is available in a drop down list. If the scope of generations is not maintained it is assumed as 00 which signifies that the Process Instruction is generated only once for this Phase. If you wish to generate it for each component or reservation item you use 01 or 02. )4 is used for All inspection Characterisitcs. Let me explain it with an example. If the Process Instruction Category is such that it holds a few Material Information (like Material Number, Quantity Required, Unit of Measure etc), then you might be interested to generate this Process Instruction for all the components assigned to the Process Order and you use 02 or 01 in this case ( I believe you know the difference between Order items and Reservations). This will ensure that the Process Instruction is created Multiple times for for every component assigned you shall find a separate Process Instruction. I used in while sending the component list to the External ME system where we need to send all the Component details attahced to the Order. Similarly for all Inspection Characterisitcs also you can generate the Process Instructions by this setting. 05 and 06 are used if you wish to generate the Process Instruction for Predecessors and Sucessors Phases. this might be also one of the reason that you can see Process Instructions getting generated for a Phase though it has directly never been assigned to it in O10C.

      2. Filter--> Similarly the Filter is used to generate Process Instruction based on certain criteria that you decide. First Provide a Name to the Variant and Press Enter and it shall take you to the detail screen where you can set your criteria. e.g. Order Type. We used this in generating a specific Process Instruction for a specific Order type. Also you can set the filter by filtering based on Component number and Item type and hence in a way i is just fine tuning you Scope of generation based on you defined and designed criteria. Remember one more thing, The Variant is saved in a WORKBENCH request and hence is a cross client setting, so better to be sure before setting this

      Hope this helps you in some way

      Regards,

    Namaste,

    just for curiosity: What is the business need to use process instructions that are maintained in customizing of control recipe destinations? We had some customers that did so in the past but decided to use XSteps and Standard XSteps instead. The fact that process instructions of control recipe destinations are maintained via customizing is a disadvantage for productive systems (of the regulated environment). Especially when you have to change the process instructions that are assigned to the control recipe destination.

    Some more details about control recipe destinations (CRD):

    • Control recipes that do have control recipe destination 1 create ABAP list-based PI Sheets. This type of PI Sheet is outdated since R/3 4.6C and doesn't contain advanced features and functions.
    • Control recipes with control recipe destination 4 generate browser-based PI Sheets when sent to the destination. Process instruction maintenance using XSteps is possible (and recommended).
    • Control recipes with type 2 ("external control recipe") transfer their process instructions to external systems via the PI-PCS interface. Sending process is triggered by SAP ERP system. Process instruction maintenance using XSteps is possible ( but not as comfortable as for CRD type 4)
    • Control recipes with type 3 ("external control recipe") also transfer their process instructions to external system via the PI-PCS interface. The sending process is triggered by the external system. Though some customers have been able to use XSteps for creation of such control recipes, XSteps aren't released to support CRD of type 3

    Regards

    Process instruction categories are standard process instructions that have been predefined in Customizing for Process Management

    If you want to create process instructions in the master recipe and process order, you must always enter a process instruction category that has been predefined in Customizing. The characteristics of this process instruction category are copied into the process instruction. You can, however, change or delete the characteristics and assign process-specific values to them. You can thus adjust your process instructions to the specific requirements of your master recipe or process order.

    Process Management -> Process Instructions -> Define Process Instruction Categories (General).

    Dear,

    Process instruction categories are assigned to phases in master recipe. These Process instruction categories have process have relevant Process instructions that are sent to control recipe and carry the process messages that are received back.

    Hope it helps.

    • Thanks Sahil for your response. That is I am well aware of, but thecase here is that only the control recipe destination is set-up in the Master Recipe Operations and it is still able to automatically assign the PI categories in the order. I would like to know where to configure the PI categories assignment for process order. As I mentioned there are PI categories assigned in the control recipe destination however I don't know how these are getting assigned to the operations on the process order upon control recipe creation.

    Hello Jay,

    Also please check wat is the control recipe type whether it is 1, 4 OR 2,3

    1,4 are for PI sheets and are generated at process order release and 2,3 are for Process instructions categories.

    Thanks
