Hi Jaisree,
It depends upon the Object interconnected while capturing the data during the transfer.
Rough example - 1 material x 32 Plants (material available in all 32 plants, Both Material & Plant checked in your IM) = 32 Objects.
From SAP Help
When you create an integration model, you select filter objects by entering object types (for example, material masters and sales orders) and other selection criteria (for example, customer number and material/plant combination) and then assign these to a model name, target system and application. When you activate the integration model, the system checks which data objects have the same properties as the filter object. At the initial data transfer, the system selects these data objects and transfers them to SAP APO. For the change transfer, it only transfers the corresponding data objects.
