Hi Uma pathy,
Question 1:
If you are going to work with planned independent requirements, then you should assign the planning strategy.
Please read the help:
Planning Strategies - Assembly-to-order (LO-ASM) - SAP Library
You must assign the strategy group to the material (in the material master record), so that the system can determine the correct requirements type automatically.
You can also assign the planning strategy via the MRP group. You do this by assigning the strategy group in Customizing for Demand Management to the MRP group. In this case, the MRP group is assigned to the material in the material master record.
Question 2:
You can control the batch creation in the production scheduling profile:
Automatic Batch Creation - Process Orders (PP-PI-POR) - SAP Library
You can make the following settings in Customizing (production scheduling profile):
- No automatic batch creation in the process order
- Automatic batch creation on order creation
- Automatic batch creation on order release
The configuration is done in t-code: CORY.
Kind Regards,
Mariano
