I am using BPM for the first time and have tried to reach at a certain stage. The process is
Legacy File(MQ Series)-------> SAP XI(Validation)
<------ Back to legacy if Error
SAP XI(Via Proxy)One record at a time -
> SAP R/3(Validation on Data)
Back to XI with validated Data(Via Proxy)
SAP XI(Validated Data Posted via IDOC) -
> SAP R/3
The STEP 2 and 3 will be repeated for every record and 'N' Number of Idocs will be posted and finally the Error if any will be posted back to legacy system.
I have designed Interfaces(Abstract also) for every process, but dont know what all objects and process to put in BPM. The First receive step contains the abstract interface for receieving message in BPM. Need to understand how to proceed in building the above scenario.
If possible kindly notify the steps involved and how to build this one. When and where I need to use Transformation, Switch and block etc.
