Everyone knows enterprise and personnel structures are the cornerstones to an effective SAP ERP HCM system; however, these structures can present challenges to even the most experienced administrators. This session walks through the building blocks of the enterprise and personnel structures in SAP and provides best practices for customizing them to meet your needs. Understand personnel areas, personnel sub-areas and their relationships to each other and company codes. Learn more about the interconnectedness of these structures and the implications of best and worst design practices. Learn how to organize your business needs in order to understand your unique requirements, maximize the enterprise and personnel structures categories, and to harness SAP's reporting potential. Learn how to recognize bad structures that are duplicative or don't fit your reporting needs and how to improve them. Take a look at alternative fields beyond enterprise and personnel structures that can be used to identify or categorize employees, including employment status, customer defined status, and work contract. Take home questionnaires to help guide the categorization and design process, as well as examples of good and bad enterprise and personnel structures.
