How to replace blank with "NA" while using Rex command

[manojchacko78]

I am extracting these three values and if there is any empty value in any of the fields, it returns as no result.

How i replace the blank values with NA in the rex statements

| rex field=AddtionalData "Business unit:(?<BusinessUnit>[^,]+)"
| rex field=AddtionalData "Location code:(?<Locationcode>[^,]+)"
| rex field=AddtionalData "Job code :(?<Jobcode>[^,]+)"

| stats count by  BusinessUnit Locationcode Jobcode
| fields - count

Hi @manojchacko78,

you can use fillnull to replace spaces with  "NA"

| rex field=AddtionalData "Business unit:(?<BusinessUnit>[^,]+)"
| rex field=AddtionalData "Location code:(?<Locationcode>[^,]+)"
| rex field=AddtionalData "Job code :(?<Jobcode>[^,]+)"
| fillnull value="NA" BusinessUnit 
| fillnull value="NA" Locationcode 
| fillnull value="NA" Jobcode
| stats count by  BusinessUnit Locationcode Jobcode
| fields - count

Ciao.
