Excel公式，如果一列中单元格的值保持不变，但另一列中的值发生变化，则显示给我

Question

I hope you can help. In Screen Shot 1. You can see that the number 4424383 in column Y appears 6 times from row 2 to row 7

In column U you can see the numbers 12345 and 76259 and they also appear from rows 2 to 4 and 5 to 7

What I need is a formula that can produce a piece of text that says "Investigate" in column Z, if the number in Column Y stays the same but the number in Column U changes.

If you look at Screen Shot 1 you will see the green number 4417458 in column Y and the green number 76260 in column U this DOES NOT need to be investigated.

Like wise with the purple numbers

Its only when the HUB_PARTY_ID or Y number continues to be the same but then the MTNG_ATNDEE_ID or U column number changes that I need "investigate" to appear in the Z column.

as always any and all help is greatly appreciated.

You can use the below formula starting with the third row of column Z

=IF(AND(Y3=Y2,U3<>U2),"Investigate","NA")

Result:
