Tables in Actions and Procedures (SAP Library - Variant Configuration (LO-VC))

Tables in Actions and Procedures

Purpose

In actions and procedures, tables are used to infer values.

Note

When transferring the export parameter, the inferred default value can be overwritten by the user, using the following syntax:

<formal_arg> ?= <actual_arg>

Example:

table ZSTROMQUANTITY ( month_quantity = Month_quantity,

quantity_1 ?= $self.Quantity_1_4,

Quantity_2 ?= $self.quantity_2_4,

Quantity_3 ?= $self.quantity_3_4)

if specified runtime_month_4,

Prerequisites

Actions and procedures only read the first value assignment alternative defined in the table structure.

Values can only be inferred for a characteristic that refers to the data field of the first value assignment alternative.

You must enter the variable $SELF for characteristics of the class for which you want to infer values.

You must ensure that exactly one value is inferred when you access a table – in other words, you must not have more than one value to choose from (see Value Assignment Alternatives).

Process Flow

The following example is for an action. The tables calls in actions are the same as the table calls in procedures.

Configurable material BIKE has characteristics SADDLE, SADDLE_SUPPORT, and SUPPORT_MATERIAL. The data for the saddle can determine the type of SADDLE_SUPPORT.

Choose Tools ® Table Structure ® Create.

Create table T_SADDLE and assign your three characteristics to it.

Note

All characteristics are single value, so you use the same characteristics in the table and in the class.

Characteristic SADDLE is defined as a key field in the value assignment alternative:

Characteristic

Key Field

SADDLE

X

SADDLE_SUPPORT

SUPPORT_MATERIAL

Choose Tools ® Table Contents and enter the following combinations of values:

SADDLE	SADDLE_SUPPORT	SUPPORT_MATERIAL
SR_ErgoGel	Patent support	Steel
SR_Gel	Standard support	Steel
Touring_saddle	Standard support	Aluminum
MTB_saddle	Special patent support	Aluminum

Create action ACT_SADDLE_SUPPORT. The characteristics in the class are compared with the characteristics of the table. First, you refer to the characteristics in the table, then to the characteristics in the class. The characteristics of the class are referred to with $SELF:

TABLE T_SADDLE

(SADDLE = SADDLE,
SADDLE_SUPPORT = $SELF.SADDLE_SUPPORT ,
SUPPORT_MATERIAL = $SELF.SUPPORT_MATERIAL)

Assign this action to the configuration profile.

Result

In the class, assign a value to characteristic SADDLE. The table call in the dependency finds the correct table line and infers values for SADDLE_SUPPORT and SUPPORT_MATERIAL.
