Sr. SAP Workflow and ABAP Consultant

Designed and built a cross system material creation application. Used BRF+ rule engine to map existing parts in one system to new material being built in different system. Materials were created and extended using default values and/or mappings that could be overridden at process time.

Designed and built generic approval workflow based on rules in a BRF+ rule engine. This rule engine completely separated all the business rules from the approval workflow. The rules determine how many approval types are required based on rules that classify the object (vendor master), of each approval type, how many approval steps; which approval types are sequential and which are parallel.

Designed and developed Generic Object Services (GOS) enhancements to allow the ‘Store Business Document’ service to store business documents during a creation transaction (before the business object number is created). This allowed the ‘Create Attachment’ service to be disabled so that all documents would be stored properly in FileNet, using ‘Store Business Document’.

Designed and built a generic workflow ALV that reports on any workflow’s task container elements. Any workflow definition can have a custom application of this report simply by configuring the container elements to be shown. BAdI technology is utilized to create hot spots for any of the container elements. In addition, authorization checks can be configured so work items will be visible on report based on authorizations.

Developed multiple workflow solutions: PO Release workflow which allows the user to approve inside of R/3 or from HTML email with WebDynpro links; AP coding and approval workflow; PO confirmation exception workflow with updates to PO if desired.

Integrated 3rd party supplier portal Taulia, which included multiple user-exits to customize the Taulia solution so it would fit Halliburton’s needs.
