Derivation may refer to: Derivation (differential algebra), a unary function satisfying the Leibniz product law; Derivation (linguistics) · Formal proof or derivation. Derivation definition is - the formation of a word from another word or base (as by the addition of a usually noninflectional affix). How to use derivation in a. Definition of derivation - the action of obtaining something from a source or origin, the set of stages that link a sentence in a natural language to its und.
The standard derivation strategy contains:. Steps for determining units of measure for the quantity fields assigned in the Sales and Distribution SD application or in planning. In general, you can copy the standard derivation strategy as it is. If you have created user-defined characteristics, you should nevertheless enhance the standard derivation strategy with several additional derivation steps, provided that logical dependencies exist.
For information of additional options for changing the standard derivation strategy, see the section Changing the Standard Derivation Steps.
Each derivation step describes how a group of target fields can be populated with values derived from a group of source fields.
One or more values are derived from the combination of values in the source fields and then entered into the target fields. To find out which fields are valid as source fields and target fields, refer to the section Source and Target Fields. There are different derivation types to represent the different logical dependencies between source and target fields see Derivation Types.
You can modify the order for processing the individual derivation steps by entering conditions governing how the step is carried out and by specifying step and field attributes see Influencing the Standard Derivation Procedure. Example You use the "Customer group" field from the material master KNA1 as a characteristic in your operating concern.
End of the example. Features Characteristic derivation is performed with the following: Manual account assignments, including: Automatic transfer of data from other applications, including: When hash and hash-algo are given, a fixed-output derivation is created—i.
If, in addition, recursive? In that case, the reference graph of each store path is exported in the build environment in the corresponding file, in a simple text format. Likewise, disallowed-references , if true, must be a list of things the outputs may not refer to.
This is only applicable to fixed-output derivations—i. This is the case for small derivations where the costs of data transfers would outweigh the benefits. This is useful, for instance, when building packages that capture details of the host CPU instruction set. It is kept as-is, uninterpreted, in the derivation. As can be guessed, this primitive is cumbersome to use directly. A better approach is to write build scripts in Scheme, of course!
For more information, see G-Expressions. Return a derivation that executes Scheme expression exp as a builder for derivation name. Optionally, env-vars is a list of string pairs specifying the name and value of environment variables visible to the builder.
Derivation definition, the act or fact of deriving or of being derived. See more. derivation definition: 1. the origin of something, such as a word, from which another form has developed, or the new form itself 2. the origin from which something. (mathematics) The operation of deducing one function from another according to some fixed law, called the law of derivation, as the of differentiation or of.
