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 VSE because the strategy group has been set to 52.
See the Table of Planning Strategy Assignments.

2. The requirements are passed on to MRP. The stock/requirements list (Logistics ® Production ® MRP ® Evaluations ® Stock/reqmts list) for the finished product 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	VSE	100 -	100 -
<reqdat2>	IndReq	VSE	100 -	200 -
<reqdat3>	IndReq	VSE	100 -	300 -

1. Procurement requisitions are created in the MRP run (Logistics ® Production ® MRP ® Total planning). The stock/requirements list for the finished product 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	100	100
<reqdat1>	IndReq	VSE	100 -	0
<reqdat2>	PlOrd.	1235/IndR	100	100
<reqdat2>	IndReq	VSE	100 -	0
<reqdat3>	PlOrd.	1236/IndR	100	100
<reqdat3>	IndReq	VSE	100 -	0

 

These procurement requisitions are the starting point for production or external procurement. Various possibilities exist for handling the procurement process in the R/3 System. The following factors, however, are important for this strategy:

· Stock at finished product level is not taken into account for production.

· The planned orders are not yet "real" because production of the finished product must be executed after receipt of the sales orders. The planned orders have order type (VP). It is impossible to convert these (VP) planned orders into production orders, or to use them in a repetitive manufacturing environment. The Conversion field in the display of the planned order is not set, which indicates that it is not possible to produce this planned order.

2. The MRP run also creates procurement requisitions for the components. In this example, the stock/requirements list for the component ROH52A 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-52	100 -	0
<reqdat2>	PlOrd.	1238/Stck	100	100
<reqdat2>	DepReq	SZ-52	100 -	0
<reqdat3>	PlOrd.	1239/Stck	100	100
<reqdat3>	DepReq	SZ-52	100 -	0

 

3. The main objective of this strategy has now been reached: procurement for the components has been triggered, even without sales orders, due to Demand Management alone. Procurement of the components can occur in a variety of ways. Here we are assuming that a goods receipt (for a purchase order, for example) takes place. The stock/requirements list for all components of the material displays the following information:

Date	MRP element	MRP element data	Received/ required quantity	Available quantity
<today>	Stock			300
<reqdat1>	DepReq	SZ-52	100 -	200
<reqdat2>	DepReq	SZ-52	100 -	100
<reqdat3>	DepReq	SZ-52	100 -	0

1. A sales order for the parent material is created.

· The system will find the requirement type KSVS because the strategy group has been set to 52. See the Table of Planning Strategy Assignments.

· It is possible to confirm a quantity that has been previously planned (100 pieces for each schedule line, in this example) . The header text that says Assignment of Planned Independent Requirements indicates that this is not a check according to ATP logic but rather an availability check based on planned independent requirements.

· The system finds the schedule line category CP and the item category TAN because the item category group was set to NORM.

Suppose that for this example an order with a quantity of 90 pieces is entered with a required delivery date of today. This order can be confirmed after the first planned independent requirement date <reqdat1> if the consumption parameters have been defined accordingly and this date can be found. For more information, see Consumption Strategies and Logic.

2. After entry of the sales order, the stock requirements list for the parent material displays the following information:

Date	MRP element	MRP element data	Received/ required quantity	Available quantity
<today>	Stock			0
<today>	Order	000333/0010/001	90 -
<today>	® Planning w/o assembly			90 -
<reqdat1>	PlOrd.	1234/IndR	100	100
<reqdat1>	IndReq	VSE	10 -	90
<reqdat2>	PlOrd.	1235/IndR	100	190
<reqdat2>	IndReq	VSE	100 -	90
<reqdat3>	PlOrd.	1236/IndR	100	190
<reqdat3>	IndReq	VSE	100 -	90

1. After a second planning run, the stock/requirements list of the parent material displays the following information:

Date	MRP element	MRP element data	Received/ required quantity	Available quantity
<today>	Stock			0
<today>	Order	000333/0010/001	90 -	90 -
<t+rlt>	PlOrd.	1237/Stck	90	0
<today>	® Planning w/o assembly			0
<reqdat1>	PlOrd.	1234/IndR	10	10
<reqdat1>	IndReq	VSE	10 -	0
<reqdat2>	PlOrd.	1235/IndR	100	100
<reqdat2>	IndReq	VSE	100 -	0
<reqdat3>	PlOrd.	1236/IndR	100	100
<reqdat3>	IndReq	VSE	100 -	0

 

The planned order ("Stck") for the parent material can now be converted to either a production order, a process order, or allow backflushing in the repetitive manufacturing process. This triggers the production after sales order stage. Production of this material can be performed quickly because all the necessary components are already available.

2. After creation and release of the production order (for the parent product) the stock/requirements situation remains the same. This means that the planned order is replaced by a production order.



Working with production orders is only one option for production. This process is also possible in the area of repetitive manufacturing.

At component level (ROH52x), the dependent requirements ("DepReq" in the planned order) are replaced by an order reservation ("OrdRes" in a production order).

3. Perform a Goods Receipt for the parent material, after production. Note the increase in available stock in the stock requirements list of this material.
