I have a list of Item numbers that I need broken down to their root SKUs. Some have suffixes, some have prefixes, others do not. I need help determining how to trim only those with suffixes within the list.
Example:
| Item Number | Root SKU |
| 100260 | 100260 |
| 100267 | 100267 |
| 100268 | 100268 |
| 100270 | 100270 |
| 100270W | 100270 |
| 100276 | 100276 |
| 100276P | 100276 |
| 280591 | 280591 |
| 280591A | 280591 |
| PRM2840 | PRM2840 |
| TCK1524 | TCK1524 |
| WHU4016 | WHU4016 |
| WHU4059 | WHU4059 |
| WHU4072 | WHU4072 |
| WTI0956 | WTI0956 |
| WTI0957 | WTI0957 |
