如何将高级过滤表达式添加到 Informatica Data Integration Hub

Question

I am working in a project with Informatica Data Integration Hub. We are evaluating the idea to use FILTERS in the subscription site:

• Basic Filter expressions
• Advanced Filter Expressions

In the following picture I'm using some examples of basic expressions ( just for testing purposes, don't think about the meaning of those basic filters, they have no meaning at all ).

I cannot find anything in the documentation regarding which syntax should I follow for these advanced filter expressions. What I read in the documentation is that the filter conditions in advanced expressions should follow the rules of "Powercenter Expressions"

Can anyone tell me where I can find the documentation about the syntax of those expressions? Does anyone know why I can put whatever I want in the advanced expression field and it is not even evaluating for syntax purposes?

Thank you

Here's a the filtering condition doc briefly covering the topic.

Here's a document on working with expressions in Informatica.

Basically it's all pretty Excel-like. You pick a function, put arguments in brackets and that's it.

Now, the difference between basic and advanced filtering is, that in basic mode you put several conditions that need to be met at once, as Informatica is using AND to combine them. In case you need more anvanced AND/OR logic, you need to use the advanced expressions and write the complete syntax on your own.
