Converting Planned Orders Collectively 
Use
If several planned orders exist in the same plant, you can simultaneously convert them into process orders via collective conversion. This is what is usually done in integrated production planning and control.
Procedure

If you select without a planning plant, the MRP controller you enter cannot be checked. In this case the system will warn you.
In the Material field you can search with any character string (for example, A* , for all materials starting with the letter A).
If you want to limit the selection of the planned orders to be converted according to your opening date, you can also enter an interval in the Opening date range fields.
If an opening horizon is already defined in your user master record (parameter IDs, AEV, and AEB), the values are automatically suggested by the system.
The system lists all planned orders that correspond to the selection criteria you entered. You can display a planned order by double-clicking it (number of the planned order in the Planned order column).
In the list of the selected planned orders, you can call up dependent objects by double-clicking a planned order or material.
The system converts all selected planned orders.

A log is created for each planned order for which the conversion is called up. You call up this log by choosing
in the Result column.
You can make a new selection of planned orders at any time. To do this, display the selection area with Selection parameter on/off, enter the selection criteria and choose
.
Only planned orders which allow in-house production are proposed for selection. To convert planned orders into requisitions, choose Logistics ® Production - process ® MRP ® Planned order ® Convert pur. req. ® Collect. conversion.
