  Key Concepts: 
  A checking group is a feature of SAP's Material Requirements Planning (MRP) component. It is used to group materials together for the purpose of MRP calculations. The checking group is used to determine which materials are affected by a particular MRP run. It can also be used to limit the scope of an MRP run, so that only certain materials are included in the calculation.
  
  How to use it: 
  The checking group is set up in the material master record. It can be assigned to a material or a group of materials. When an MRP run is executed, the system will check the checking group assigned to each material and determine whether or not it should be included in the calculation. If the material has a checking group assigned, it will be included in the calculation; if not, it will be excluded.
  
  Tips & Tricks: 
  When setting up a checking group, it is important to consider how it will affect the MRP run. For example, if you want to limit the scope of an MRP run to certain materials, you should assign those materials to a checking group and then use that checking group when running the MRP. This will ensure that only those materials are included in the calculation.
