Final answer:
The cost designator in the ERRCD code for an equipment item is replaced using a specific code that represents a cost range or category.
Step-by-step explanation:
In the ERRCD code, the cost designator represents the cost of replacing an equipment item. This code is a single letter that denotes a specific cost range. The exact code used to replace the cost designator depends on the specific range or category that the cost falls into.
For example, let's say the cost range for replacing an equipment item is divided into four categories: Low, Medium, High, and Very High. In this case, a code such as 'A' might represent the Low category, 'B' might represent the Medium category, and so on.
It's important to note that the specific codes used for the cost designator can vary depending on the system or organization implementing the ERRCD.
