Updating one column based on reference values in the same table

[virgo0984]

Hi, I have a table 1 with the following values:
ITEM LOCATION SS_DAYS
316TA/JP415 052 21
316TA/JP415 062 0
316TA/JT266 052 43.17
316TA/JP415 062 0

I have table 2 with the relationship between item and location from table 1. That table reads as follows
Original SKU Loc_ORG Replacement_SKU Repl_LOC
316TA/JP415 052 316TA/JT266 052
316TA/JP415 062 316TA/JT266 062

I want to use Table 2 to replace the values of Original SKU/Location with value sof Replacement SKU/location in Table 1. Thus, my results in Table 1 after updating should look like this

ITEM LOCATION SS_DAYS
316TA/JP415 052 43.17
316TA/JP415 062 0
316TA/JT266 052 43.17
316TA/JP415 062 0
