I was wondering if there were people out there who had the need to maintain ABAP code in multiple versions of SAP simultaneously. If so, what is your approach to do this efficiently?
Further explanation: My company is a software company that develops software to integrate with SAP. As such our customers use different versions of SAP ranging from 4.6C to ECC 6.0. Currently we are maintaining four different code bases to accomodate the differences in syntax and underlying architecture. I was wondering if anyone knew of any code management software, or if they had any creative business processes that they would be willing to share to make this as efficient a process as possible.
