When you define the interim storage area, you also specify the type of coordinate that will be used to identify the storage bins within the interim storage area. Storage bins for an interim storage area can have:
The following graphic illustrates the use of all three types of interim storage bins.
For each interim storage area, you can define one or several storage bins with fixed coordinates. For example, for the goods receipt area, you can create a fixed storage bin with the coordinates GR-AREA. You then assign a separate movement type to each storage bin in the interim storage area. You do this by entering the storage bin coordinates into the movement type record when you define the movement type.
Before you can post stock movements using movement types containing storage bin coordinates, you must first create the corresponding interim storage bin in WM.
When you post a goods receipt in the IM component, the system uses the movement type to select which interim storage bin will receive the stock quantity in the interim storage area. On the other hand, when you post a goods issue, the system uses the movement type to determine from which storage bin in the interim storage area the stock will be removed.

When you define a movement type, you can set up the system to create dynamic storage bins in the assigned interim storage area. In this case, the system uses the document number which triggered the stock movement as the coordinates for the interim storage bin.
For example, for a goods receipt, you can set up the system to use the purchase order number as the storage bin coordinates in the interim storage area for goods receipts.
These coordinates only exist as long as the quant is in the interim storage bin; afterwards, they are deleted.
Advantage of Using Dynamic Coordinates
The advantage of using dynamic coordinates for goods receipts for purchase orders is that when several goods receipts are posted, these postings then create separate quants which can be differentiated using the purchase order numbers as coordinates.
If predefined coordinates are used, only the total quantity of the material in the interim storage area is visible.
Fixed Bin Coordinates
For a movement type, you can also assign a fixed storage bin that has been defined in the WM view of the material master record. You enter this storage bin coordinate in the Storage bin field in the storage bin stock section in the material master at thestorage type organizational level (see Material Master Data). In this case, when you define the movement type you have to enter the storage type from the material master as an interim storage area in which the fixed bin has been defined. When the material is received in the warehouse, it is then posted directly to the assigned fixed bin. For the goods receipt posting, the system does not create a transfer requirement. In this case, none is required.
When Should I Use Fixed Bin Coordinates?
You should use this procedure, for example, for fixed bin picking or in situations in which good system performance is important and when you can do without a return notification of the putaway.
