Restrict the Entity while file Uploading

Hello Expert,

I have Upload Multiple Material through multiple step for same CR number for multiple material processing CR type (MAT0A) i.e

Step-1 

If User-1(ABC) want to upload Few Entities Like (Material, Material Accounting Data, Material Costing Data , Material Valuation Data, Plant Data Basic Data & Plant ATP Data) .They Submit the CR and its goes to Next User(XYZ) .

We want to rest all the Entities restrict for User-1(ABC).

Step-2

User-2(XYZ) want to upload few Entities Like (Plant Data Foreign Trade, Plant Data MRP Forecast, Plant Data MRP Lot Size, Plant Data MRP Misc., Plant Data MRP Production Planning, Plant Data MRP Stock Planning & Plant Data Purchasing) ,But now User-2(XYZ) is able to upload all the Entities (Including already uploaded by User-1(ABC) ).
