Ui action button to upload an attachment of type only excel and csv

[Kishor O]

I have created a UI action Bulk task once the user clicks on the button it prompts to select an attachment.
Now I want it to accept only Excel and csv files.
How can I achieve this?

Hi @Kishor O ,

you should avoid customizing the OOB UI macro. you should try using the business rule on sys_attachment.

Business Rule Condition and Script:

you can just avoid the attachment from getting attached to the record but infoMessage or alert is somewhat difficult

Condition: current.table_name == 'my_table' // add the tableName of your table here

Script:

var fileName = current.file_name.toString();

  if(fileName.indexOf(".xls") != -1||fileName.indexOf(".csv") != -1){

  gs.addInfoMessage("File should be xls(or) CSV file"); // but this was not coming while I tested, you can explore on this

  current.setAbortAction(true);

  }

If I could help you with your Query then, please hit the Thumb Icon and mark it as Correct !!
