If it’s a public out of box view in Acumatica graph, you need to write a view delegate and append the where statement. If you want to keep everything as is and add a condition then you can use WhereAnd to add extra condition in your delegate. There are quite a few examples for view delegate on community that you can utilize and edit.
please note the delegate must have the same name of original view but the first letter should be in lower case.
@charithalakshan49 In addition to my previous comment, I found my earlier case that I had a little bit more complex requirements that I did something and I’m confident you will extract what you need from it and ignore the rest. Here is my post from sometime ago:
@aaghaei is correct in his statement. Good catch. WhereNew will fully replace the content of the original Where clause. Take that in consideration if you decide to go with that approach.
