ERPConnect SAP Table Join and filter (Query) without creating a SAP Query

Question

I know very little about SAP and I have been asked to extract some data from it using ERPConnect (and if required LINQ to SAP)

I can see that it is possible to create BAPIs and Queries in SAP but these need to be pre-defined within SAP and then ERPConnect can be used to get data via those BAPIs and Queries.

Is it possible to use ERPConnect to create a query for me, instead of the Queries needing to exist in SAP? i.e. Join and filter several Tables and return the results?

I am also opposed to extracting data for 3 very large tables and then working out the joins and filtering it afterwards, my intention is to generate the query first and then only get what I need.

Answer 1

The best way would be to have someone code the selection in ABAP, wrap it in a RFC-enabled function module and use it. If for some reason this is not possible, you might want to look at RFC_READ_TABLE - but be aware of its limitations, there are numerous questions about it here. I find it hard to give more detailed recommendations based on the rather vague question.

Sorry, I know this is late, but there is an alternative. You could develop a general-purpose remote-enabled function to which you can pass your query (including joined queries), and execute it within SAP, returning the results to the caller. ERPConnect also includes built-in query capability. I wouldn't dismiss it without investigating further. I've done many queries against SAP tables using ERPConnect.
