Hi @Da9 ,
In fact, "Created By" is the LookUp Column in the Dataverse, but the Search function is only used to search for text. The Addcolumn() function helps you create a temporary table without making any changes to the data source.
Search:
Search(
AddColumns('0711AS',"CreatedName",'Created By'.'Full Name'),
Control1Name.Text,
"ColumnName",
"CreatedName")
if you do not want to use AddColumn Function, we suggest you try Filter:
Filter('0711AS',Control1Name.Text in 'Created By'.'Full Name' || Control1Name.Text in 'ColumnName')
Hope this will help you,
Best Regards,
Tina
