Purpose

This process describes how you can create and edit characteristic-based process instructions in the process instruction overview. In this way, you define the information that is combined in control recipes and sent to process control when you have released the process order.

As well as characteristic-based process instructions, you can also maintain XSteps using the XStep editor. For more information, see (XSteps) Execution Steps .

Prerequisites

The following settings have been made in Customizing for Process Management :

Process instruction categories defining the function and contents of your process instructions (that is, the process instruction type and characteristics) have been maintained.

In Customizing, you define the following for a data request:

– The number of messages you want to create for it and the message category to which these messages belong

– The characteristics of the message category you want to transfer to the message

– Where and how characteristic value assignments takes place (for example, in the process instruction or in the PI sheet)

An appropriate value assignment function or table field has been allocated to those process instruction characteristics whose value is to be assigned automatically when you create the control recipe.

The process instruction categories of the process instructions, which are required in all control recipes and are therefore to be generated automatically when the control recipe is created, have been assigned to your control recipe destinations.

Process Flow

In the master recipe, you create the process instructions that are not generated automatically.

When creating process instructions, you refer to a process instruction category. The process instruction automatically obtains the same type as the process instruction category to which it refers. The remaining data (characteristics and characteristic values) is copied to the process instruction and can be edited there.

You adjust the copied data to meet the requirements of the corresponding processing step. You can change or delete existing characteristics, or add new ones.

In a data request, you add:

The values for the message characteristics (if known), that are not automatically valuated in the process order or PI sheet.

The text for the input request and, if you use them, input validations

If you do not want to use all message characteristics, you delete the ones you do not need.

You create a process order with reference to a specific master recipe.

When copying the recipe data, the system also copies the process instructions to the process order. If required, you can add more process instructions in the order.

You add information to the process instruction to meet the special requirements of the process order.

In a data request that you use to report a measurement reading, you enter the name of the measuring device connected to the resource you have selected.

By now, a value must have been assigned to all process instruction characteristics, which have not had values assigned to them automatically on creation of the control recipe.

If you want, you can start characteristic value assignment in the order to check and, if necessary, change the values assigned automatically.

When the process instructions and other order data are complete, you release the process order.

You create the control recipes for the order. The system completes the process instructions as follows:

It generates the process instructions defined in the control recipe destination and adds them to the process order and control recipe.

Characteristics, for which the valuation depends on the scope of generation, have their values assigned directly.

If you specify that a process instruction containing the most important material data is generated for each reservation item, the characteristic value for the reservation item is assigned automatically.

It assigns a value to those characteristics to which a function or table field for automatic value assignment has been allocated in Customizing, provided that a value has not yet been assigned manually.
