SAP Workflow Course – Section 10-01: Containers and Bindings 2

Containers

Contents:

• Containers

• Container bindings


Containers: Objectives

At the conclusion of this section, you will be able to:

• Create a workflow container element

• Create a task container element

• Define a container binding

• Create a diagram of container bindings


Containers: Business Scenario

• The ‘material’ business process you want to support with workflow has dialog steps

• Information passed into a task is imported at the beginning of the workflow or produced by prior steps

• You want to know how data is stored in containers and can be used in later steps

Runtime: object reference to object typein accordance with data type reference

Runtime: value has data type in accordance with data type reference

Data type reference to object typein object repository

Data type reference to field in ABAP dictionary

Container: Definition/Runtime

• Table-like data structure used for

– Field values

– Object references

What data has to move in order to support the process?

Binding

• Design question at definition time:

– Definition of modeling and assignment rules which are implemented at runtime for

• Transferring data in one container to another container

• Assigning (initial) values to some container elements

• Runtime

– Binding definition is executed at runtime

• Meaning data is moved from one container to another

Containers: Section Summary

• Containers are table-like data structures

• Containers contain control information for the workflow system

• Containers are used for field values and object references

• During runtime the different containers provide each other with necessary information (binding definition transfersdata from one container to another)
