Hi,

Do you really need to use makeresults ?

You can try something like this

| makeresults
| eval B_field=""
| append [ makeresults | eval B_field="Test"]
| eval result=if(isnull(B_field) OR B_field="","Dummy_Data",B_field)

index=app_core sourcetype=app_log apple_cluster_name=APP_TEST is_scheduled=1 eai_acl_owner=* 
| eval 
    [ search index= app_core sourcetype= app_log apple_cluster_name= APP_TEST is_scheduled=1 eai_acl_owner=* 
    | eval 
        [ search index= app_core sourcetype= app_log is_scheduled=1 apple_cluster_name= APP_TEST eai_acl_owner=* 
        | rex max_match=0 field=search "savedsearch\s{0,}\"{1}(?<anotherSavedSearchUseInSearch>(\w+){0,})" 
        | stats count values(dataStatus) as dataStatus dc(anotherSavedSearchUseInSearch) as rexCount 
        | eval dataStatus = if(count == 0 ,"dataDoesntExist","dataExists") 
        | eval dataStatusAndRexStatus = dataStatus.",".rexCount 
        | return dataStatusAndRexStatus ] 
    | eval dataStatus = mvindex(split(dataStatusAndRexStatus,","),0) 
    | eval rexCount = mvindex(split(dataStatusAndRexStatus,","),1) 
    | rex max_match=0 field=search "savedsearch\s{0,}\"{1}(?<anotherSavedSearchUseInSearch>(\w+){0,})" 
    | eval anotherSavedSearchUseInSearch = case(dataStatus == "dataDoesntExist","NoTitle2", rexCount == 0,"NoTitle2",rexCount > 0,anotherSavedSearchUseInSearch) 
    | stats values(anotherSavedSearchUseInSearch) as Title2 delim=" " 
    | nomv Title2 
    | return Title2]

From subsearch ——> Title2 is returning some value.

But mainsearch (index=app_core sourcetype=app_log apple_cluster_name=APP_TEST is_scheduled=1 eai_acl_owner=* ) —> This is common ,
1. doesnt have any data in it , then it is showing error : Error in 'eval' command: Arguments are missing. Usage: eval dest_key = expression.
2. if data exists , then it doesnt thrown any error.

The query should also work when data doesnt exists.

As stated in the other question (https://answers.splunk.com/answers/726353/subsearch-returns-empty-value-main-search-also-ret.html) you can use a eval Title2=coalesce(Title2,"") to ensure your subsearch returns a valid result.
