Documentation
Definition
A workflow expression describes how a fixed value is to be determined, that is, it corresponds to a URL of a value. An expression satisfies the expression syntax and is located in one of the three following categories:
- Constant
- System field
All components of the system table can be contacted.
- Container expression
A variable (or the component of a variable) in the process context.
Use
All components of the system structure can be contacted using system fields. The name of the component is specified enclosed by percentage symbols ('%').
The most flexible way to address data is by using container expressions. All process relevant data in the workflow environment is stored in a container, which forms the namespace for the entire process and for each of its steps. A container element (variable in the process context) can be contacted using its unique name. If the container element has a structure (for example, a business object or an ABAP structure), its components can also be dereferenced over any number of nesting levels. The syntax for container expressions is as follows: The expression is enclosed in an ampersand ('&'), the dereference symbol is a period ('.').
Example
'A string', 17, '19:25:59', ... The expression itself is a value in a constant.
%DATE% Refers to the current system date (SYST-DATE).
&FORM& Specifies the container element called 'form'.
&FORM.ISSUER& Specifies the component 'issuer' of the 'form' element.
