Automatic Value Assignment to Process Instruction Characteristics

Use

You can use this function to transfer data maintained elsewhere in the system to your process instructions.

This graphic is explained in the accompanying text.

Using automatic characteristic value assignment, you can copy the long text maintained for a phase or the material data maintained in the material list to your process instruction.

If you want the system to generate process instructions when you create a control recipe, a value must be assigned automatically to all characteristics whose value has not yet been assigned in Customizing. Otherwise, you cannot create the control recipe.

Prerequisites

There are two ways of automatic characteristic value assignment:

Automatic value assignment during process instruction generation

You can assign values in this way if the characteristic has been defined for it in the standard system (see below).

Automatic value assignment during control recipe creation

You can assign values in this way if a value assignment function or table field has been assigned to the characteristic in Customizing.

Features

Automatic Value Assignment During Generation

You can only use this type of value assignment for specific standard characteristics. It depends on the scope of generation (see table below).

This graphic is explained in the accompanying text.

If you have selected the scope of generation For all reservation items , the item for which the corresponding process instruction has been generated is assigned to characteristic PPPI_RESERVATION_ITEM (reservation item).

Characteristic Value Assignment and Scope of Generation - Dependencies

Scope of Generation	Characteristics with Automatic Value Assignment
For all reservation items and order items	PPPI_MATERIAL_ITEM PPPI_RESERVATION_ITEM
For all reservations	PPPI_BATCH PPPI_MATERIAL (Material number) PPPI_MATERIAL_CO_PRODUCT (Co-product indicator) PPPI_MATERIAL_CONSUMED (Quantity of material consumed) PPPI_MATERIAL_ITEM PPPI_RESERVATION_ITEM PPPI_MATERIAL_PRODUCED (Quantity of material produced) PPPI_MATERIAL_QUANTITY PPPI_MATERIAL_SHORT_TEXT PPPI_STORAGE_LOCATION
For all order items	PPPI_ORDER_ITEM_NUMBER (order item)
For all inspection characteristics	PPPI_INSPECTION_CHARACTERISTIC
For all predecessors	PPPI_PREDECESSOR
For all variable activities of phases	PPPI_STD_VALUE_PARAMETER_ID (Parameter ID of the standard value)

Automatic Value Assignment During Control Recipe Creation

When you create a control recipe, this type of value assignment is used for characteristics for which the corresponding Customizing settings have been made (see Prerequisites ) and whose values have not yet been assigned.

If you want to check and, if necessary, correct the values determined automatically before you create the control recipe, you can also start value assignment manually in the process order. Note, however, that the characteristic values are not automatically updated when you later change the relevant object (for example, the material list for material characteristics).

The standard system contains a number of characteristics to which a value assignment function has been assigned. In these functions, the characteristic value is often determined according to values of other characteristics assigned to the same process instruction. The sections below give an overview of these dependencies.

This graphic is explained in the accompanying text.

The A indicator (automatic value assignment) is set in the characteristic overview of the process instructions for characteristics whose value is assigned automatically when you create the control recipe. For information on the value assignment logic for standard characteristics whose value is assigned using a function, see the field help for this indicator.

This graphic is explained in the accompanying text.

Assigning Values to Material Characteristics - Dependencies

In automatic characteristic value assignment, material data is determined as follows:

For the relevant material component, if the characteristic for the item number of the material components (PPPI_MATERIAL_ITEM) is contained in the process instruction

For the relevant reservation item, if the characteristic for the reservation item (PPPI_RESERVATION_ITEM) is contained in the process instruction

For the relevant material component, if the characteristic for the order item (PPPI_ORDER_ITEM) is contained in the process instruction

For the header material in all other cases

This graphic is explained in the accompanying text.

If you use batch determination, note the following:

For the system to be able to determine the batch single record, we recommend using the characteristic PPPI_RESERVATION_ITEM in the process instruction. Characteristic PPPI_MATERIAL_ITEM is not unique since there may be several batches for one material item.

To ensure the correct value assignment of all characteristics, always use process instruction generation if you use batch determination.

This graphic is explained in the accompanying text.

Assigning Values to the Unit of Measurement - Dependencies

A value is only assigned to the unit of measurement automatically if a quantity has been determined automatically in the same process instruction before.

This graphic is explained in the accompanying text.

The unit of measurement of the material quantity is automatically assigned to the characteristic if a value has been automatically assigned before to one of the following characteristics in the process instructions:

PPPI_MATERIAL_QUANTITY

PPPI_MATERIAL_CONSUMED (quantity of material consumed)

PPPI_MATERIAL_PRODUCED (quantity of material produced)

This graphic is explained in the accompanying text.

Assigning Values to Activity Characteristics - Dependencies

A value is only assigned automatically to characteristics for variable activities if a value has been assigned to the characteristic for the corresponding parameter ID of the standard value (PPPI_STD_VALUE_PARAMETER) in the process instruction.

This graphic is explained in the accompanying text.

Assigning Values to Resource Characteristics - Dependencies

Using the value assignment function COAV_RESOURCE_CHARACTERISTIC, you can copy characteristic values that have been entered during resource classification to your process instruction characteristic. One of the following requirements must be met:

The name of the process instruction characteristic is identical to that of the classification characteristic.

The name of the classification characteristic has been assigned as a value to the immediately preceding process instruction characteristic.

This graphic is explained in the accompanying text.

Grouping Input Values - Dependencies

A value is only assigned automatically to the characteristic for grouping input values if the following requirements are met:

If the item number of an inspection characteristic (PPPI_INSPECTION_CHARACTERISTIC) is contained in the process instruction, the description of the inspection characteristic is assigned to the characteristic for grouping input values.

If the material number (PPPI_MATERIAL) is contained in the process instruction, the material number is assigned to the characteristic for grouping input values.
