Hi Amit,
Deployment Heuristics "Real-time or not" will consider only one level via Transportation Lane b/w source and destination. It does not evaluate the entire network as such. In SNP02, the option to maintain destination locations can be used to maintain your markets A B C and stock locations X Y Z but the sequence in which these locations are evaluated to determine the Source by Deployment cannot be controlled which may lead to inaccurate results.
The best approach would be to split the SNP02 into 2 legs. Deployment from Plant 1 2 3 to Stock Locations X Y Z and then include Deployment STR's in ATD receipts for products at X Y Z and deploy to Markets A B C. This would give better data reconciliation / troubleshooting and be even more beneficial if you are using different Planning Book/ Data Views for these locations since this Solver is totally based on Macros to calculate Total Demand and Total Receipts.
