Optimization Tool:Error in .check_constraints.L_constraint(constr,x):

I am trying to solve room utilization use case(place as many events as possible in the available rooms) with the help of optimization tool. I am getting this error when I run the workflow.

The configuration of Optimization Tool:

Where am I going wrong?

@MaliniLakshman I would check out the new and improved help doc. I provided a few key pieces that they incorporated into the help doc recently. My suggestions:

1) Not related to your error, but I would always display the field mapping for anchor O. This can prevent  mistakes in case you don't have the casing right (Variable instead of variable) or spelling right (variabel instead of variable).

2) I would verify that in your A input, the first field is named variable.

3) I would verify that all of your constraint columns in the A input are numeric datatypes (click on the line going into the A input).

4) for the B anchor, I would use a select tool to get it down to just 2 columns (dir and rhs, in that order). Make sure rhs is a numeric datatype. from the help doc:

• dir: a string, direction of the constraint inequality. It has to be >=, <= or ==.
• rhs: a number, the right hand side of the inequality, corresponding to b.

5) I would make sure that if you have x columns of constraints in your input A, you have x rows in input B.

If that still doesn't solve it, try and provide sample data or a dummy dataset that is giving you the same problem.
