Parallel Workflow feature using standard Supplier template WS54300005

Hello Experts,

I am having one requirement to implement the parallel workflow for supplier creation WS54300005 using SWDD tcode.

Could anyone please explain what are the steps required to enhance this workflow template accoridng to our requirement and how much it is feasible to achieve without using rule based workflow template.

My requirement is there are only one requestor and two approvers(parallel) which will be decided based on valuess fetch from some zcustom table.

P.S:- I am newbie to ABAP workflow concept, i.e. SWDD tcode

Any useful help will be appreciated.

Regards

Ashu
