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.
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
