Batch Bill of Material

Use a batch bill of material to accommodate physical constraints, such as ovens or vats, in industries where products are produced in fixed quantities.

MRP plans orders to fill net requirements by using one or multiple batch quantities. If the system does not find a batch quantity for the net requirement, it uses the next larger batch size. If larger batch size does not exist, MRP uses multiples of the closest smaller batch size until the requested amount is supplied.

MRP functions differently when you have defined multiple batch bills of material.

When only one batch bill exists, the MRP system uses the batch quantity as a:

• Multiple if the net requirements are greater than the batch quantity.

• Minimum if the net requirements are less than the batch quantity.

This table displays the resulting MRP planned order for one batch bill of material:

Batch Quantity	MRP Requirements	Resulting MRP Planned Order
1,000	1,500	1,000
		1,000
1,000	967	1,000

If multiple batch bills of material exist and the net requirement is greater than all of the batch quantities, then the system uses the largest batch quantity in combination with any of the others to satisfy the requirement.

This table displays the resulting MRP planned order for multiple batch bills of material:

Batch Quantity	MRP Requirement	Resulting MRP Planned Order
400	1,500	1,000
600		600
800
1,000
400	3,000	1,000
600		1,000
800		1,000
1,000

If multiple batch bills exist and the net requirement does not match, but is less than the largest batch quantity, then the system uses the smallest batch bill that satisfies the requirements.

This table displays the resulting MRP planned order for multiple batch bills of material with requirements that are less than the largest batch quantity:

Batch Quantity	MRP Requirement	Resulting MRP Planned Order
400	780	800
600
800
1,000
