What causes this issue?

You are trying to assign an inspection plan to a testing schedule item
(storage condition) that is not compatible with the strategy of the

strategy, or the strategy it uses is not identical to the one that was
created for the testing schedule.

System Response

You can only assign an inspection plan to a testing schedule item for a
stability study if the inspection plan uses the same strategy as the
testing schedule.

Select an inspection plan that uses the same strategy as the testing
schedule. You can use the function "Select Inspection Plan" to do this.
