Q1 What is the key structural difference between ISSG and Unconstrained Security Groups in Workday?
Answer: An Integration System Security Group (ISSG) is specifically constrained to integration system accounts for automated API calls and batch feeds. Unconstrained Security Groups give access across all organizations without organizational scoping, whereas Constrained groups restrict access based on target Supervisory Orgs, Companies, or Cost Centers.
Q2 How does ESI (Extract Single Instance) work in Workday Calculated Fields?
Answer: ESI evaluates a multi-instance field (e.g. all Dependents or all Historical Cost Centers) against specific filter conditions and returns a single target instance (such as the First, Last, or Specific matching record) so subsequent Calculated Fields (like LRF or TF) can extract values from it.
Q3 When should you use Workday Studio over an EIB or Core Connector?
Answer: Use Workday Studio when requirement involves complex conditional branching, multiple data source aggregation, custom XSLT 2.0 transformations exceeding 10MB, asynchronous file splitting/merging, or bi-directional web service calls. EIB is best for simple flat-file extract/load, and Core Connectors for standard third-party vendor integrations (like Benefit carriers or ADP).
Q4 What are the main components of a Workday Extend App architecture?
Answer: A Workday Extend app consists of PMOD (Presentation & Model Object Definitions) for data structures, Custom Pages built with Page Builder components, REST Orchestrations for business logic, and custom Business Process (BP) step event definitions.
