Hi,
For your first point. Please check below
You need to create a derived table in Data Foundation Layer of Universe in IDT. The query should have the placeholder syntax for the input parameter.
Follow these steps:
1. Create a parameter in data foundation of IDT. This will be the prompt visible to the end user while executing the report.
2.Create a derived table in Data foundation in IDT
3. Use the following syntax for the SQL required in derived table:
SELECT <col1>,<col2>... FROM <viewname> ('PLACEHOLDER'=('$$IP_PSTNG_DATE$$',<prompt>))
In the above syntax, PLACEHOLDER is a keyword,
'$$IP_PSTNG_DATE$$' is the input parameter created by you in your view and <prompt> should be replaced by the actual prompt created by you in step 1.
Now create your business layer using this derived table. This should bind the Input Parameter with the front end prompt.
