Hi VishApte
My experience with the manifest is that you cannot find information on which mapserver layer id that correspond to which dataset. Also, the order of the datasets in the manifest does not correspond to the order of the layers in the map service, even for a simple service using a single database and no group layers.
Do you have a simple way to do this? The only way i've found is to download a complete service backup, extract it and the MSDs inside, then traverse the xml-files inside to connect the layer id with the correct dataset.
Thanks!
