Process steps sequence & process diagram

Hi All,

I'm new to the BPMON and I work on solman technical areas and no exposure on functional area. I have few questions about the BPMON setup and solution documentation.

Is it necessary to define the process steps in sequence for a process. For eg :

Process : E2E_OTC_Sale-from-Stock (CHARM-Development) .

The process steps defined under the above process are:

These are defined by default in solution documentation by SAP. I'm not sure if the below shown steps are in sequence steps for the above process.

Because, I was trying to create a process, based on the business flow diagram received from our function team. I created the process diagram with the sequential steps mentioned as in business flow diagram sent by our functional team. But when I checked in solution documentation browser (in below page , for the process that I created), I see that the process steps are not in sequence when compared to the process diagram I have created for my process (eg: New Folder).

Is it necessary to define the process steps in sequence in the browser? If yes, how do move the positions of process steps as I'm not able to do it.

Is there any relation between the process diagram and process steps?

In what scenarios, the type "Transaction , Process <Link>,Document (best practice), collaboration Diagram... below shown) will be used.

I couldn't find any information on the below tppic. Please help to provide the wiki / KBA/ your inputs.

Regards,

Satish
