Question1: How to save sample data from SOAP UI ? or any alternative Solution to this

We are trying to create a data model through CatalogService Soap API(we used the createObject() method), we successfully created it but we didn't find a way to save sample data through it. This is a problem when we try to create report for that data model as it requires some sample data to be saved for the layout and template builder for the report.

Our ask is that is there a way to save sample data from soap api call? or is there any alternative to this problem?

Question2: Our second question is about the selection of 60 columns limitation. While building sql query for data model from UI, we were not able to select more than 60 columns in the sql query. We wanted to know about this limitation as it is restricted us to retrieve all the columns for a table in a single report. Can you suggest a workaround for this?

Question3: How to add the Authorization services in SOAP UI for Oracle BIP WSDL SOAP APIs?

Question4: How to identify custom objects while building sql queries in data model?

Question5: How to store reports in UCM storage? Is there a way we can add content server as a destination while scheduling a report job? I tried adding ucm storage as one of the destination but the connection of it wasn't successful even though our UCM is setup correctly and is working fine in BICC.
