Good practices to improve model performance

General recommendations

It is important as model calculations increase to ensure that the calculations and structures are as optimal as possible. Easy checks include:

• Ensure the dimension order in the "applies to" is consistent
• Consider if all of the dimensions for the calculations are necessary
• Reduce the number of line items with the same formulas (calculate once, reference many times)
• Consider the use of subsets and line item subsets
• Use a balanced approach to sparsity
• Ensure "text joins" are optimal

See the following articles for more information on the above:

Customer requirements 

General recommendations also include, whenever possible, challenging your customer’s business requirements when the customer requires a large list (>1M), a large amount of data history (this should be kept out of the planning model if possible), and high number of dimensions used at the same time for a line item (>5).
