Displaying MM Customizing – Release Strategy (4) 
The overview displays a list of strategies and their descriptions, sorted by group.
You can define the strategy description and the release codes you want to use. The release codes TD, KY, and EX are used here. You can also define user-specific prerequisites, strategies and classifications in this menu.
The dialog box shows that the release code TD has no prerequisites. The release code KY has code TD as a prerequisite. For release code EX you also have to release the code KY.
You can change these selections as required. You can define alternative release codes for multi-level release strategies by selecting the relevant prerequisites, or by removing existing selections.
Here you can define the indicators for the purchase requisition status. You do this before release and after each combination of release codes. The purchase requisition is blocked before release. After you use release code TD, the purchase requisition is still blocked. After you use release code KY, you can create a request for quotation with reference to the purchase requisition. After you release EX, you can create a request for quotation and/or a purchase order with reference to the purchase requisition.

Note that there are three alternative release sequences: EX,TD-EX, and TD-KY-EX lead to status 2 (RFQ/PO).
The system displays a list of fields defined for releasing purchase requisitions in the classification class (FRG_EBAN). Each default value has already been entered in a field. The stock value field has been limited to one interval. All other fields in CEBAN are also available using the classification structure.
The system displays the current status of the release procedure. You can now change the strategy.
This simulates the effect of release code TD, and the purchase requisition is still blocked.
This simulates the effect of release code KY, and the purchase requisition is released for RFQ.
The purchase requisition is now blocked again.
