The aim of storage bin determination is to find the best physical destination storage bin for a putaway process or an internal warehouse goods movement. In addition to other data, parameters from the product master that you have defined manually or that were determined in slotting are used to do this.
Storage bin determination for putaway occurs automatically when a warehouse task is generated.
● You have created storage bins.
● You have made the settings for putaway in Customizing for Extended Warehouse Management (EWM), for example:
○ You have defined storage section search sequences under Goods Receipt Process ® Strategies ® Storage Section Search ® Maintain Storage Section Search Sequence.
○ You have defined HU types for each storage bin type under Goods Receipt Process ® Strategies ® Storage Bin Determination ® HU Types ® Define HU Types for Each Storage Bin Type.
During storage bin determination, a physical storage bin is determined by means of determining and applying the suitable strategies.
In a fixed storage bin scenario, it could be the case that the fixed storage bin has already been determined for a storage type by slotting. In this case, you do not need to determine and apply additional search sequences.
In a putaway process, storage bin determination covers the following steps:
Determination of storage types
The system first determines the storage type by determining and applying a storage type search sequence. The storage type search sequence defines in which storage types and in which order the system is to search for a destination storage bin for putaway.
You can define multiple accesses for determining the storage type search sequence. The system checks these accesses until it finds a suitable storage type search sequence.
You assign a putaway rule to each storage type in the storage type search sequence. The putaway rule specifies how a storage bin is to be determined, for example, empty storage bin.
In addition to the putaway rule, the storage behavior also plays a role. It describes the type of storage bins, for example, normal, bulk storage, or pallet storage.
If a product has the stock category Quality Inspection, it could be the case that all other parameters are unimportant. You could, therefore, define the first access in such a way that the system is to search for a storage type search sequence where only this stock type is used.
Determination of storage sections
For each storage type that is found, the system then determines a storage section by determining and applying a storage section search sequence. You can use the Business Add-Ins in the /SCWM/ES_CORE_PTS enhancement spot to implement a customer-specific logic.
Determination of storage bin types
Then the system determines a storage bin type for each storage type by determining and applying a storage bin type search sequence. You can use the Business Add-Ins in the /SCWM/ES_CORE_PTS enhancement spot to implement a customer-specific logic.
Determination of storage bins
Last of all, the system uses a certain priority to evaluate the combinations of storage type, storage section, and storage bin type that have been found. Here it tries to find a storage bin for each combination in accordance with the putaway rule.
Slotting and storage bin determination
If you use slotting, it could be the case that you want to prevent storage bin determination for products that have not yet been slotted. If, however, you do not use slotting, there is no reason to prevent storage bin determination. You can also use the IMG activity Define Warehouse Number Parameters for Putaway (under Goods Receipt Process ® Strategies) to control at warehouse level whether storage bin determination is to be permitted if slotting has not yet been performed for a product.
Following are the list of Important MM tables. Please check if its useful.

You can use the following standard characteristics to classify batches:
|Characteristic||Description and Use|
|LOBM_BWTAR||Valuation type (only for class type 022 = batch level at plant level).
You can use this characteristic as a criterion for batch determination if your batches are assigned characteristic values separately.
If you no longer use a batch, you should flag it for deletion in the batch master record. Use batch reorganization runs regularly to delete all batches flagged for deletion. A reorganization run deletes all batches flagged for deletion if they have no more stocks. The deletion of a batch does not affect the batch where-used function.
|LOBM_QNDAT||Next inspection date
This characteristic refers to the next inspection date stored in the batch master record. It is determined using the date of the last goods receipt and the inspection interval stored in the material master record.
You use this characteristic, for instance, for batches whose contents must first mature or be held before they can be processed further or sold.
Use this characteristic if you work with the shelf life expiration date (SLED)/expiration date.
If batch status management is activated, you can work with this characteristic to use the batch status (restricted or unrestricted) as a selection criterion.
In Customizing for Batch Management, you copy the standard characteristics to the current client by choosing Batch Valuation ® Update Standard Characteristics. The system creates and assigns to the standard characteristics the variant functions and dependencies that are required for using the standard characteristics in Batch Determination.
