本文深入探讨了SAPVC变式OD语法中VariantConfiguration的使用，包括操作符如AND、OR、NOT，内置条件如SPECIFIED、IN、TYPE_OF等的详细解释。此外，还介绍了列表、大小写转换、字符串拼接等特性。

SAP VC 变式 OD 语法 Variant Configuration

Operators

Operators	Use in Dependencies
AND	Two statements that are both either true or not true are linked with AND. Length = 300 and Width = 200
OR	Two statements of which at least one is either true or not true are linked with OR. Color = ‘red’ or Basic_material = ‘wood’
NOT	You can negate one or more expressions by using NOT. NOT (Color = ‘blue’) NOT (Color = ‘red’ and Basic_material = ‘wood’)
IF	Conditions in actions and procedures start with IF. Color = 'red' if Model = ‘A’

Special Features

Lists

In lists, the individual elements are always separated by commas.

COLOR = 'RED' IF MODEL = 'A', COLOR = 'BLUE' IF MODEL = 'B', COLOR = 'GREEN' IF MODEL = 'C',

Case sensitivity

In characteristic names, object variables, and operators, there is no distinction between upper case and lower case letters.

Concatenation

All letters are converted to lower case.

Leather_saddle = LC('Alpha')

= 'a'

All letters are converted to upper case.

Leather_saddle = U C('Alpha')

= 'A'

This function is important if the assigned characteristic does not allow lower case, but the assigned expression may contain lower-case letters.

The string is cut off at the maximum number of 30 characters.

Leather_saddle = Alpha || Beta

= 'AB'

List of Built-In Conditions

Expression	Implied Condition
SPECIFIED	Characteristic has a value: SPECIFIED COLOR See Built-In Condition SPECIFIED
IN	One of these values must be set: COLOR IN (‘red’, ‘green’, ‘blue’) See Built-In Condition IN
TYPE_OF	Only for certain objects: TYPE_OF ($ROOT, (Material) (300) (NR = 'U91’)) See Built-In Condition TYPE_OF
PART_OF	The object is a component of a BOM (only in constraints). See Constraints: Entering Conditions
SUBPART_OF	The object is a component of an assembly that is part of the BOM of a configurable material (only in constraints).
