Comprehensive and Detailed 150 to 250 words of Explanation From Workday Record-to-Report/Course Guide/topics:

The target cost center worktag should be mapped from the Basis section because the basis contains the dimensions and statistical values that determine how the allocation is distributed. In this scenario, cost centers 71000, 72000, and 73000 are the basis dimensions, and their respective square-footage statistics determine each cost center's pro-rata share.

The Source section identifies the amount being allocated: activity in ledger account 6100: Facilities associated with cost center 34000: Facilities. Mapping the target cost center from Source would preserve cost center 34000 on the allocated lines, which would defeat the requirement to distribute the expense to the consuming cost centers.

Within the Target component, Workday permits worktag values to be obtained from Source, Basis, or User Specified configuration. Selecting Basis causes each generated target line to inherit the cost center associated with the square-footage value used in that line's allocation calculation. The Offset component then relieves the originating facilities cost pool and normally retains the source-company and source-worktag context.

Accordingly, Basis is both the calculation driver and the correct mapping source for the receiving cost centers.
