Final answer:
The limits for voids/bottle returns that cause an "EC 90" error and require a CSDH and keys to clear vary depending on the business or establishment's policies. It is important to refer to the specific policies and guidelines set by the company or establishment in question.
Step-by-step explanation:
The limits for voids/bottle returns that cause an "EC 90" error and require a CSDH (Cashier Shift Data Holder) and keys to clear can vary depending on the policies and procedures of the specific business or establishment. In general, when a customer returns a bottle that cannot be accepted due to certain conditions such as damage or expiration, an "EC 90" error may be triggered. This error usually prompts the cashier to perform certain actions, such as contacting a manager, using a CSDH device, or inputting a specific key code to override the error and complete the transaction.
For example, a grocery store may have a policy that if a customer returns a damaged or opened bottle of soda, the cashier would need to use a CSDH device and enter a specific key code to override the "EC 90" error and process the return. The limit for voids/bottle returns causing this error would then be determined by the store's return policies.
It's important to note that these limits and procedures can vary between different businesses or industries, so it's always best to refer to the specific policies and guidelines set by the company or establishment in question.
