get attachment.sys_id before catalog item is submitted

[Mart Sinimaa]

Hi all,

i need to have somehow to get attachment.sys_id before catalog item is submitted. (so I can't use current.sys_id...)
The use case is as follows: check whether the file is in the correct format, size, etc.

Hi there,

Is this for a Catalog Item on the Platform UI or Service Portal?

If you are on Paris, you could also have a look at variable type Attachment. This can be used with 2 attributes, to validates extension and size.

If my answer helped you in any way, please then mark it as helpful.

Service Portal

And is this for just the Catalog Item with for example Catalog Client Script? Or about a custom widget to be set up?

If just Catalog Item AND Service Portal... you can't query the sys_attachment table for the correct attachment, because you don't know the sys_id of the sc_req_item (not yet created) or the cart (cart sys_id is added initially on the attachment). 

For Platform UI this would be possible, though Service Portal 😞

Though maybe the variable type which I mentioned would do for you, if you are on Paris-release.
