Hi, can anybody please help me on: while I am triggering client script from external Suitelet version 1.0, I am getting INSUFFICIETN_PERMISSION or Insufficient Privileges error during nlapiSearchRecord() API execution? I have made search public still I am getting the same error.

I am not 100% sure, but can you please try this. In the suitelet deployment, change execute as role to admin, or to some role that has permission for viewing the search record as well as all the join records.
