We are dealing with a prospect that has an SAP system (R/3 4.0B) that is used, at a minimum, for invoicing and accounts receivable. We wish to provide them a solution based on our non-SAP technology, but need to get infomation on customer accounts and open invoices.
It would be nice to do a tight integration and query directly into the SAP system, we have been unable to find any documentation that explains a methodology for performing this access from an external system. Does anyone have any advice on a starting point? We have talked to SAP who directed us to the IFR.SAP.COM site, but that repository assumes that one has extensive knowledge of SAP to begin with.
It would be acceptable to us to perform periodic extracts of entire invoice and customer tables to create an external repository. It seems that using IDOCs would be the starting point for this, but again we haven't been able to glean what we need to know to actually make this work.
We're hungry for the information we need to be able to implement our solution. But the more things we look at the less we understand what is needed. Does anyone have any knowledge of what steps we need to take to begin an implementation? We don't even know what questions we have to ask at this point.
