How to Make Attachment Mandatory in Record Producer ?

[BlackCoder16]

I created a Record Producer and want to make attachment mandatory when service changes and before submission of the Record Producer. 

When I added one file from record producer then I saw it stored that file in attachment table as sn_customerservice_case in table name column instead of sc_cart_item_producer . so i did put query as

getAtt.addQuery('table_name', 'sn_customerservice_case');

but it's not working.

How can I able to do it , please help me ?

Note : Application Scope : Customer Service

Hi @BlackCoder16 ,

On record producer,you can check the "mantadory attachment" in portal settings.

Thanks,
