WE use a third-party Project management System identified as FIELD1 (Cost Accounting Control). This is his how they manage project billing for labor cost. We are using an extensible flexfield (PERSON) to associate this to the employee. We have defined Custom Attributes with Table Value sets to allow the filtering in the Time Entry Layout Components. There are three fields (custom attributes) and three Custom Time Entry Layout Components. They are FIELD1. FIELD2 and FIELD3.

Rows in the EFF:

Unique Identifier, Field1, FIELD2, FIELD3, Start Date, Completion Date and Status
