Updating a formula that removes a specific text string from a concatenation in Excel

The current formula in Column E, shown below, concatenates Columns A, B, C and D to create a unique Product Number:

=A2&IF(B2<>"","-"&B2,"")&IF(C2&D2<>"","-"&C2&D2,"")

Open in new window


I need to update the current formula whereby if the specific text string "-AAU" is in Column B, it is not to be included in the final concatenated Product Number in Column E.

I have included a sample spreadsheet that has the current formula in Column E, and the updated, desired results I am looking for in Column F.

Thanks in advance for assistance with this...

Try this

=A2&IF(B2<>"",IF(RIGHT(B2,4)="-AAU","-AAU","-"&B2),"")&IF(C2&D2<>"","-"&C2&D2,"")
