1. Planned independent requirements are created for the production plan. For information on how to create planned independent requirements, see Creating Planned Independent Requirements with Reference or Creating Planned Independent Requirements Without a Reference.

The system finds requirements type VSEB because the strategy group has been set to 59. See the table of planning strategy assignments.

2. The requirement is passed on to MRP. The stock/requirements list (Logistics ® Production ® MRP ® Evaluations ® Stock/reqmts list) for the phantom displays the following information:

Date	MRP element	MRP element data	Received/ required quantity	Available quantity
<today>	Stock			0
<today>	® Planning w/o assembly
<reqdat1>	IndReq	VSEB	100 -	100 -
<reqdat2>	IndReq	VSEB	100 -	200 -
<reqdat3>	IndReq	VSEB	100 -	300 -

1. Procurement requisitions are created in the MRP run (Logistics ® Production ® MRP ® Total planning). The stock/requirements list for the phantom displays the following information:

Date	MRP element	MRP element data	Received/ required quantity	Available quantity
<today>	Stock			0
<today>	--> Planning without assembly
<reqdat1>	PlOrd.	1234/IndR	100	100
<reqdat1>	IndReq	VSEB	100 -	0
<reqdat2>	PlOrd.	1235/IndR	100	100
<reqdat2>	IndReq	VSEB	100 -	0
<reqdat3>	PlOrd.	1236/IndR	100	100
<reqdat3>	IndReq	VSEB	100 -	0

 

This procurement requisition is the starting point for production or external procurement. You have a variety of options for handling the procurement process. The following factors, however, are most important in this strategy:

· At phantom assembly level, stock is not taken into account.

· The planned orders are not yet "real" because production of the phantom assembly must be executed after receipt of the production order (or the schedule line in repetitive manufacturing). The planned orders are independent requirements with order type VP. This order type cannot be converted (note the Conversion field in the display of the planned order). This ensures that it is not possible to produce yet. It is impossible to convert these (VP) planned orders into production orders or to use them in a repetitive manufacturing environment.

2. The MRP run also creates procurement requisitions for the components of the phantom assembly (In this example, SZ-59 is the phantom assembly). The stock/requirements list for a component displays the following information:

Date	MRP element	MRP element data	Received/ required quantity	Available quantity
<today>	Stock			0
<reqdat1>	PlOrd.	1237/Stck	100	100
<reqdat1>	DepReq	SZ-59	100 -	0
<reqdat2>	PlOrd.	1238/Stck	100	100
<reqdat2>	DepReq	SZ-59	100 -	0
<reqdat3>	PlOrd.	1239/Stck	100	100
<reqdat3>	DepReq	SZ-59	100 -	0

 

3. The main objective of this strategy (procurement for the components of the phantom assembly) has now been reached, even without an order. In this scenario, we assume that a goods receipt (for a purchase order, for example) takes place. The stock/requirements list for all components of the final assembly displays the following information:

Date	MRP element	MRP element data	Received/ required quantity	Available quantity
<today>	Stock			300
<reqdat1>	DepReq	SZ-59	100 -	200
<reqdat2>	DepReq	SZ-59	100 -	100
<reqdat3>	DepReq	SZ-59	100	0

1. A sales order is created for a finished product whose BOM uses the phantom assembly. A planned order for the finished product is created that includes (at least) the phantom assembly and the components of the phantom assembly. The requirements type of the finished product is not important.
2. After a second MRP run, the stock/requirements list for the phantom assembly displays the following information:

Date	MRP element	MRP element data	Received/ required quantity	Available quantity
<today>	Stock			0
<today>	® Planning w/o assembly
<reqdat1>	PlOrd.	1234/IndR	50	50
<reqdat1>	IndReq	VSEB	50 -	0
<reqdat2>	PlOrd.	1235/IndR	100	100
<reqdat2>	IndReq	VSEB	100 -	0
<reqdat3>	PlOrd.	1236/IndR	100	100
<reqdat3>	IndReq	VSEB	100 -	0

 

The independent requirements for the phantom assembly have been consumed, resulting in reduction of the planned independent requirements.

3. A reservation was therefore created one level lower, shifting the source of the requirement from the independent requirement to the sales order. The stock/requirements list of the component of the phantom assembly displays the following information:

Date	MRP element	MRP element data	Received/ required quantity	Available quantity
<today>	Stock			300
<today>	Ord.Res	SZ-59	50 -	250
<reqdat1>	DepReq	SZ-59	50	200
<reqdat2>	DepReq	SZ-59	100 -	100
<reqdat3>	DepReq	SZ-59	100 -	0

 

Today’s dependent requirement was created by the planned order for the finished product (containing the phantom assembly and the component(s) of the phantom assembly). The other dependent requirements were created by the independent requirements.

4. Now a production order is created for the finished product (Logistics ® Production ® Production control ® Order ® Create).

• An availability check can be performed for all components of the order (Component ® Availability ® Check availability). For more information, refer to Availability Check.
• The source of a requirement for a component of the phantom assembly is shifted from the planned order to a production order.

Date	MRP element	MRP element data	Received/ required quantity	Available quantity
<today>	Stock			250
<reqdat1>	DepReq	SZ-59	50	200
<reqdat2>	DepReq	SZ-59	100 -	100
<reqdat3>	DepReq	SZ-59	100 -	0
