Adding a character to certain values in a column

Hi , theu1996 

As mention by  UAV-Test-Pilot  ,If the data is lost in excel，I would suggest you to  format  you table column as text in excel before  you enter data.

Then check whether the data lost in data previews.

For how to fill in the missing data, please follow the steps below：

1.exacte the first character of  column"machine"

2.create custom column "missingdata" as below:

custome column formula as belowL

=if [Plant] = 17 and ([First Characters of Machine] <> "0")  then 0 else ""

3.merge column "misssing data" and  column"machine"
