I believe you are trying to concate two string values and with space separator. Please find below the code snippet for the same , i hope it helps.

 

Case 1:

String concate code with space separator:

 

${str:concat(str:concat(record:value('/"employement_details.0.CurrentCompany"'),' '),record:value('/"employement_details.0.c2HhPayroll"'))}

 

Case 2:String concate code with nospace separator:

${str:concat(record:value('/"employement_details.0.CurrentCompany"'),record:value('/"employement_details.0.c2HhPayroll"'))}

 

Case 3 : String concatenate without str:concat function :

${record:value('/"employement_details.0.CurrentCompany"')}  ${record:value('/"employement_details.0.c2HhPayroll"')} ${record:value('/"employement_details.0.ctc"')}

 

 

Thanks & Regards
