What does "Not compatible with previous inputs or available publisher inventory" mean?

When initiating an investment based activity prediction, and while adding media constraints, you may experience this error message after trying to save a constraint: "Not compatible with previous inputs or available publisher inventory". 

This is due to the violation of either of the following media constraint checks:

• Logical violation: your media constraints can be mutually violating each other, if they are not compatible
  • Violation example 1: you input a fixed constraint for "TV" investments of 1.000.000, but your total activity budget is only 750.000.
  • Violation example 2: you input a max constraint for "TV" investments of 200.000, but you also input a constraint for investments on the TV broadcaster "SAT1" of 300.000.
  • Violation example 3: you input a fixed constraint for "Digital Display" of 400.000, but you also input a max constraint for "Digital Display" of 350.000

• Media inventory availability violation: we check whether your requested media constraints are viable in relation to available media inventory
  • Violation example 1: you input a fixed constraint for "TV" investments of 100.000.000 for a period of 2 days
  • Violation example 2: you input a max constraint for "TV" investments of 10

We are working on providing more understandable and contextual violation messages, for you to easier understand what exactly you violated and why.
