Example: Array notations in automation scripts
When variables with relationship path bindings are resolved at run time, the scripting framework constructs and inserts a standard array object into the script code. The script code references the required array of values by the variable name you declared in the launch point configuration.
Example
Business logic needs to be implemented
so that the total material cost that is associated with a work order
is calculated. An object launch point is defined on the WORKORDER
business object. You define a variable called matcostarray to
represent the array of material costs. The binding for this variable
uses a relationship path MATUSETRANS.linecost*
. The
relationship path traverses a pre defined relationship called MATUSETRANS.
Traversing this relationship gives the script access to all of the
MATUSETRANS business object records associated with the work order
to retrieve all material costs. The variable is directly referenced
in the script code:
if matcostarray is not None:
if len(matcostarray)>0:
for value in matcostarray:
if value is not None and value !=0:
totalmatcost += value
- Check whether the array object is valid.
- Check whether the array contains multiple elements.
- Loop through the array to retrieve each element.
- Sum the individual values into the local variable totalmatcost.
