Cost lines, generated in the itfm_allocation_aggregate table, were a multi-model data. With this you can view cost split in any segment combination, which did not help in performance or save the database space. Generating controlled cost lines helps you to control the allocation lines that is required for your business needs.

1. Navigate to Financial Modeling > Cost Models > All.
2. Enable the Generate Controlled Cost Lines check box to generate cost lines of the amount aggregated at the account level in the itfm_allocation_aggregate table.
3. If you require the sub-bucket information of the generated lines, then select the Include sub-Bucket Info check box.

   The generated controlled cost lines are sufficient to plot single dimension charts along with the buckets.

4. Define breakdown relationship explicitly to view reports on relationship between two segments.

   The engine then generates the additional breakdown allocation lines in the itfm_allocation_breakdown table, which help to plot two-dimension chart between segments. For example, IT Shared Service contribution to Business Unit.

5. Select a segment in Choose Segments for GL Expense Lines to generate GL expense lines for the segment in the itfm_allocation table.
