Hi,
I am building a small optimization model, I am getting "Constraint does not exist" error message. I am not able to identify why I am getting this error. can anyone please help?
Thanks,
Sourabh
This error was generated because a line item referenced in the constraint referenced multiple levels of non-dimensionalized line items. Optimizer works best when relationships are defined in lists and parent hierarchies with dependencies limited to one level removed. Modeling with parent hierarchies and lists items will allow your input line items to be defined by simpler formulas -- let Anaplan do the work!
You can troubleshoot this error by temporarily removing the formula from the line item and running the Optimizer action. If Optimizer is then able to solve the problem, the issue can be isolated to that line item and you can look at simplifying/flattening its formula.
In our case, a second error came up in how the syntax of a constraint was phrased. After changing the syntax, the Optimizer ran successfully.
I am developing a small production optimization model. I am getting following error.
Can anyone please help me to resolve it?
My model details are as below -
My objective function is to maximize the profit. Profit is calculated as Total Price – Total Cost. Price is assigned to End items while the Cost is assigned to Components.
The production plan is constrained by work center capacity. Apart from capacity following are other constraints –
The blue print view for the constraint is as below –
The blue print view for PP_Optimization module is as below –
The action configuration is as below –
@samaplanThanks for your inputs. These are really helpful.

I have faced lot of such issue and realized that if we do complex calculation and use output in the constraints creation , was getting the issue you specified.
Best is keep all the variable on side of the equaiton and all the constants on other side,
such issue would not appear

I have A6 as the parent list and two sibling lists: A6.5 and A7. The A7 list includes an attribute that maps to A6.5. In the UX, the user will select A6.5 using a content selector, and the grid (dimensioned by A7) should display only the A7 items associated with that selected A6.5. Since the selector is a page context and…
A quick reminder of the Bulk Copy functionality. Bulk Copy allows you copy large volumes of data from one slice of a model to another in a single, optimised operation, instead of using formulas or imports. Use case: copy a version (RF1) into a prior year version (PY RF1) using a versions list to allow for year-on-year…
