Question

What is the best way to access table data from a SAP system?

I tried it with it RFC_READ_TABLE, but this RFC returns the data in concatenated form within a single column and has a size restriction for row data.

Is there a better way to access SAP data in generic form without creating custom RFCs into the system?

I am searching for a standard RFC solution, not a custom script.

If I understand your question right, you want to read a table, but at time of programming, you don’t know which table.
With Select * from (tablename)you can read with a dynamic table name.
The target field can be defined dynamic with create data.

An example (untested, currently I have no access to an SAP-system):

  DATA: lv_tablename TYPE string,
        ev_filelength TYPE i.

  lv_tablename = 'mara'. "e.g. a parameter

  DATA dref TYPE REF TO data.
  CREATE DATA dref TYPE TABLE OF (lv_tablename).

  FIELD-SYMBOLS: <wa> TYPE ANY TABLE.
  ASSIGN dref->* to <wa>.
  SELECT * FROM (lv_tablename) INTO TABLE <wa>. "Attention for test, may be large result
  "<wa> is like a variable with type table mara
