Inventory Reconciliation

Hi Expert,

I want to do reconciliation of inventory stock in hand with ECC and BW.We have already implemented inventory dataflows in BW  for BF,BX & um with all the logics of inventory and populating data in report.

Now I want to reconcile stock information with ECC in BW.

Now since the logic used in BW is quite complex it is not one to one mapping from ECC.To reconcile the data from ECC we can develop a virtual provider based on recociliation datasource which will directly fetch the data from ECC.

But I can't understand what all logics and tables should be used to develop reconciliation datasource in ECC to bring inventory stock information in directly into BW from ECC so that we can reconcile the data.

Any help will be appreciated.

Thanks,

Neetu
