SAP WM Interview Question

The SAP Warehouse Management system (WM) provides flexible, automated support in processing all goods movements and in managing stocks in your warehouse complex.

An instruction to move materials from a source storage bin to a destination storage bin in a warehouse complex at a specified time.

Storage bins In Warehouse Management, Storage bins are master data created either from the application menu or in Customizing. Based on this master data, the stock overview in Warehouse Management shows the exact whereabouts of a material quantity in the warehouse.

  • LT01
  • LT10

Two transactions are available to create a transfer order for moving partial stocks within a warehouse number:

  • Create Transfer Order without Source Object (transaction code LT01)
  • Create Transfer Order from Stock List (transaction code LT10)

The system determines the storage location when it creates the outbound delivery and copies it into the delivery item. The storage location entered in the order item is used in the outbound delivery.

A request to transfer of materials at a particular time from source storage bin to Destination storage bin in same warehouse complex.

Stock Types :

  • Unrestricted
  • Blocked

Quality Storage Types:

  • Rack
  • Open
  • Shelf

Interim Storage types:

  • Goods Receipt area
  • Goods Issue area
  • Posting change
  • Difference
  • FIFO: To sale the oldest material first
  • LIFO :To sale the latest material first
  • Put away: Next empty bin, addition to the existing stock, mixed storage, fixed storage, open storage.

Storage unit is a container in which a material stored or transported where as Handling unit the combination of material and Packaging material.

Second TO has to be created at delivery level to move the stock from intermediate storage type to Goods issue (delivery) area for loading the stock into vehicle.

SPRO->Logistics Execution->Warehouse Management ->Strategies ->Define Put away Strategies and Logistics Execution->Warehouse Management ->Strategies ->Define Stock Removal Strategies.

Warehouse structure contains a Warehouse number, Storage types, Storage sections, storage bins and finally quant.

For Rack, Open and shelf storage types the picking strategy is FIFO. Put way strategy for Rack, Open, Shelf, CRD and Fixed Bin is Next empty bin, Open storage, open storage, open storage and fixed bin respectively.

PO, Inbound Delivery, Transfer Requirement, Shipment and TO.

Control to confirm TO for Put away and Picking can be configured at Warehouse, Storage types and Movement types levels.

Each and every storage type and storage section contains a row of storage spaces which are known as storage bins in WMS. The coordinates of the storage bins can tell us the position in the warehouse where goods are stored.

Quant is the stock of any material with similiar features in one storage bin. Different batches of a material are managed by system into various different quants. Quant quantity can be increased by an addition to existing stock. The quants can only be created or deleted via goods movements.

A storage unit is a logical group of single or multiple amount of material like pallet or a container which can be managed within a warehouse as a unit that belongs together. Storage unit (SU) management in the Warehouse Management (WM) allow us to optimize warehouse capacity and control material flow with the help of storage units within the warehouse.

Storage unit (SU) management in the Warehouse Management (WM) allow us to optimize warehouse capacity and control material flow with the help of storage units within the warehouse.

There are two types of Storage units :

  • Homogeneous Storage units which contains only one material item
  • Mixed or Heterogeneous Storage units which contains multiple material item.

In the Warehouse Management system (WMS), there are two types of goods movements:

  • Warehouse movements only affecting the warehouse
  • Stock transfers within a warehouse (warehouse number)
  • Posting changes
  • Warehouse movements also affecting the warehouse environment
  • Putaway
  • Picking
  • Stock transfers between different warehouse numbers

TR is an instruction to move materials from a source storage bin to a destination storage bin in a warehouse complex at a specified time, but a TO is the confirmation to move the material.

  • 101 – GR Receipts
  • 102 – GR PO reverse
  • 601 – GI delivery
  • 602 – Cancel GI delivery
  • 651 – Sales return
  • 909 – GR Amendment Excess


In Warehouse Management:

  • Manually in the batch split screen of the delivery item
  • Using automatic batch determination when creating the outbound delivery

Outbound delivery plant defined in Customer material information master record, outbound delivery plant defined in ship-to party master record, Outbound delivery plant defined in material master.

when ever u do the GR system will generates one Quant number based on the combination of Material, Batch, and Bin.

A posting change generally refers to a bookkeeping change – a change in information – about a particular material. For most posting changes, such as changing a batch number or releasing blocked stock, the goods themselves remain in the same physical location.

Reasons for Making Posting Changes Posting changes are made for several reasons.

These include:

  • Releasing stock from inspection into available stock
  • Converting blocked stock to inspection stock
  • Designating available material as inspection stock
  • Changing a Material Number
  • Splitting available materials into two or more batches
  • Converting special stock, such as consignment stock or returned stock, into the companys own stock
  • Changing ownership of stock in the same warehouse from one plant to another

Yes, it is in the Purchase Order. One of the primary ERP modules developed by SAP, SAP SD helps manage shipping, billing, selling, and transportation of products and services of an organization. This module is basically used to store customer and product data of an organization. SAP SD is important as it is responsible for managing customer relationships starting from raising a quotation to the sales order to the billing of a product or service. Also, when integrated with other SAP modules, SAP SD becomes a really handy module when it comes to managing sales and distribution holistically.

  • Sales Area: An entity which is required to process an order, sales area is comprised of a distribution channel, a sales organization, and a division.
  • Distribution Channel: This channel contains information about which products and services are distributed by an organization to its end users.
  • Division: A division is basically an organization structure that represents product and service lines in a company.

The organization structure in SAP SD pertains to two major steps:

  • Creation of organization elements in the SAP system
  • Linking each element as per requirements

Sales organization appears at the highest level and is mostly used for distributing goods and services. It is advised to keep the number of sales organizations as minimum because that way the process of reporting can be streamlined.

Yes, SAP MM (Material Management) module is integrated with SAP SD.If a sales order is to be created in SAP SD, it is necessary to copy the details of items from SAP MM. Availability check of items, pricing, creation of inbound and outbound delivery of goods, shipping details, loading point, etc. are also managed from data which is ingested from Material Management.

Link Point SAP Module Involved:

  • Availability Check SAP MM
  • Credit Check SAP FI
  • Costing SAP CO/SAP MM
  • Tax Determination SAP FI
  • Transfer of Requirements SAP PP/SAP MM

Inquiries from customers consist of one or more items that contain the quantity of products in the order. Quantity is divided into business lines, and they further contain various sales parameters. Items are combined in a hierarchy, and therefore it becomes possible to differentiate between batches. All valid conditions on items are mentioned in item conditions. These conditions can be valid for the entire sales order.

3 Tabs. General Data, Company Code and Sales data.

Master Data refers to the characteristics of an object whereas transaction data refers to all the transactions that are carried out using the object. Any data which does not change so frequently in master data like configuration settings like company data, personal area etc. Any data which keeps changing so often in transactional data, like employee data.

In this case, we are using third party process. This process uses a purchase order (Which is sent to you by vendor). Also, invoice verification is used further along the process to check that the invoices you send to your customer are the same material and quantity as that which the vendor sent to the customer (But obviously shipped directly to your customer).

SAP have provided a lot of reports in each module. However, if the standard reports do not meet the business requirement, we can develop our own reports. ABAP custom reports are called z reports because any program developed have to start with Z.
