SAP PI : ccBPM / BPE tables

ccBPM stands for Cross-Component Business Process Management.
“Cross-component Business Process Management (ccBPM) contains functions for enhanced service orchestration that are based on integration processes.

An integration process is composed of a specific flow of steps – including the sending and receiving of messages – during which the status of the process is persisted on the Integration Server.” (source)

BPE stands for Business Process Engine.

“The Business Process Engine (BPE) processes integration processes at runtime. Since the BPE uses functions of the Workflow Engine and generates workflows from integration processes at runtime, you must customize the Workflow Engine automatically by using transaction SWF_XI_CUSTOMIZING before you can use the BPE.” (source)
