Run MRP Single Item, Multi-level (MD02)
Purpose
Use this procedure to do an MRP run for an individual material at multiple levels. This is known as single-item, multi-level planning.
During single-item, multi-level planning, the material's Bill of Materials (BOM) is exploded and dependent requirements are created for assemblies and components. These components are also planned to cover dependent requirements. If the components have BOMs, they are also exploded and the system carries out the planning run for the components. The system repeats this process until all BOM levels have been planned.
Trigger
Perform this procedure when you must do an MRP run for an individual material at multiple levels.
Prerequisites
The following must exist:
Demand, e.g. planned independent requirements.
Material BOMs.
Material master data with MRP planning views created.
Navigation Path
Use the following navigation path to begin this transaction:
Select to go to the Single Item Multi-Level screen.
Helpful Hints
The following hints may assist you when running this type of MRP operation.
For daily MRP runs, NETCH (net change planning) provides the MRP Controller with all information about any MRP controlled material that has been impacted by recent demand. The MRP algorithms have been thoroughly optimised so that the run time and processor load is kept to a minimum.
Field Description Tables
The R/O/C column of each Field Description table indicates whether the field usage is:
R - Required in SAP.
O - Optional in SAP.
C - Conditional in SAP.
Procedure
1. Start the transaction using the navigation path.
2. Double click on
Single Item Multi-Level to go to the
Single-Item, Multi-Level screen.
3. Complete the following fields:

NETCH (Net Change Planning)
In net change planning, the system only plans materials that have undergone a change relevant to MRP since the last planning run
NETPL (Net change planning in the planning horizon)
You can also use a planning horizon to further limit the scope of the planning run. In "net change planning in the planning horizon", the system only plans materials that have undergone a change that is relevant to the planning run within the period which you defined as the planning horizon.
Regenerative planning (NEUPL)
The system plans all the materials that are contained in the planning file. While this appears to be an option, it can only be used in background planning, not single item planning.
4. Click
checkbox to insert a tick if you want to display the material list.

If you set the indicator, then all components contained in the BOM are planned and the system places the planning results in the main memory without initially saving them to the database.

The planning results are displayed automatically in the material overview. Exception messages warn you about problems at a lower BOM level. You can change the planning results to solve any problems. The system does not save the planning results until you choose
