# Why can't a user modify an order or transaction?
If a user cannot change quantities, reschedule a reservation, or access the **modify** link on a transaction, several permission or system conditions may be preventing the modification. This faq explains the most common reasons and how to resolve them.
**What permissions are required to modify a transaction?**
By default, employees **can** modify transactions. However, users **cannot** modify reservations if:
- They are assigned the **limited** permission level, or
- Custom security settings have disabled modification rights
If the modify link is missing or disabled, verify the user’s permission level.
**Why might the modify link be missing or unavailable?**
There are two main scenarios that prevent modification even when permissions are correct.
**1. The computer is not registered as a terminal**
If the device is not registered as a terminal:
- The user will **not see the modify link at all**
- The transaction page will not show modification options
### **How to fix it**
Register the terminal in:
**Admin tools → terminals → registered terminals**
Once registered, refresh the transaction page and the modify link should appear.
**2. The transaction is more than 48 hours old**
High trek pos locks transactions after **48 hours** to maintain accurate accounting. This prevents users from changing historical quantities or attendance after revenue has already been recognized.
Examples:
- You cannot reduce the number of guests from last week
- You cannot reschedule an event that occurred several days ago
### **Why this restriction exists**
After 48 hours, the transaction has already been counted in:
- Profit and loss
- Recognized revenue
- Attendance reporting
Changing it would create accounting inconsistencies.
**How do I make changes if the transaction is locked?**
You must use a **refund/return**, depending on the situation.
### **To reduce quantity and return money**
Use a **refund/return** to adjust the qty and issue funds back to the customer.
### **To reschedule a no‑show or make an exception**
1. Refund the entire order to **account credit**
2. Use the account credit to create a **new reservation** for the desired date
This maintains accounting accuracy while allowing flexibility for customer service situations.
