Dispute Cases for AR data

Hello Guys,

I have to develop Dispute Case report in which user wants to see Accounting Document number according to the dispute case IDs and also Purchase Order numbers for the same.

I am preparing report on AR (Account Receivables) data as per requirement, but PO number is not available in 0FI_AR_4 datasource.

So, my question here is does dispute cases happens in AR data only?

Please advice.

Thanks,

Saurabh
