Chevron Phillips Chemical, The Woodlands, TX

Sr. ABAP and SAP Workflow Consultant

  • GOS project: multiple imaging enhancements, ‘Store Business Document’ from create transactions, enhancement to enable/disable services based on roles and/or the BRF+ rule engine.  Examples: instead of deleting a service via SGOSATTR, disabled service to ‘Create Attachment’ if user is in a business object that has ArchiveLink business documents defined, another example: restrict users from modifying attachments if they only have display authorization for the business object they are currently viewing.
  • Imaging project: developed tools to upload, download, print ArchiveLink documents.  In addition allowed user to search business documents by business object, copy or transfer business documents to business documents of other BOR objects, e.g. copy images from purchase requisition to purchase order.
  • CFS Web Services project: built interface to upload real time transactional and master data to Oracle’s service cloud for Customer Feedback System. CFS application consumes Oracle’s REST services to upload data to cloud from SAP backend.

Halliburton – BattleRed PTP Transformation team member, Houston, TX

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.  User exits include: vendor address change approvals, PO selection, PO confirmations, AP invoices, payments and Taulia’s dynamic discounting functionality that allowed vendors to dynamically choose their discount.

LyondellBasell, Houston, TX

Sr. ABAP and SAP Workflow Consultant

  • Designed and built several workflows using the full object oriented functionality of the ABAP Classes.  Integrated older workflow technology (BOR) with new class-based so that one workflow could have different tasks that could call either.  Converted BOR-based workflows to object-oriented class-based workflows when benefits could be achieved from OO.
  • Designed custom LSO (Learning Solutions) booking and cancellation approval workflows.  The approval step was a BSP.  These workflows utilized the standard LSO BOR events that were raised via the portal.  The custom LSO workflows were designed with OO Class functionality.
  • Developed HTML email notifications for HR Personnel Transfers actions.
  • Provided production support for many complex workflows in FI, MM, HR modules.
  • Developed multiple custom workflow for various cross system applications that integrated web based front end with SAP using web services and XML and HTML.
