The document outlines the integration of warehouse management (WM) with inventory, quality management, production planning, and shipping, focusing on the WM-PP interface. It explains the scenarios for active and inactive interfaces, control cycle definitions, material staging methods, and the production supply area (PSA) setup for efficient material handling in production processes. It highlights differences in operations between active and inactive interfaces, emphasizing the importance of staging, control cycles, and movement types in material management.
WM - PP Interface
- 1. 1
- 2. Warehouse Management Overview WM interfaces with the following areas: 1. Inventory Management 2. Quality Management 3. Production Planning – This is the focus area for the following slides. 4. Shipping 2
- 3. WM-PP Interface There are two scenario in for WM-PP Interface : • WM-PP Scenario not active • WM-PP Scenario active 3
- 4. WM-PP Interface not active 4
- 5. What is Control Cycle ? For each material and PSA in the plant , one needs to define the following : 1. Storage bin to which the materials will be supplied to 2. Type of material staging. Transaction Code: LPK1/LPK2/LPK3-Create/Change/Display LS41 – List of Control Cycles LPK4-Automatic creation of control cycles for release order parts Pre-requisite : Number range defined for Control Cycle. 5
- 6. Different types of Staging Sr.No PICK PARTS Indicator=1 CRATE PARTS Indicator =2 RELEASE PARTS Indicator =3 MANUAL STAGING Indicator =4 1 Staging is process order dependent Staging is process order independent. This is used for materials stored in crates or standard containers Staging process is independent of the order. The dept. determines the quantity required Staging is process order dependent. 2 Material staging can be created manually – LP10 OR automatically Material staging is always done manually – LP11(Standard) Material Staging is done manually via- LP12 (Standard) Here staging is done manually, and used in areas where business needs to stage material incase of damage and excess consumption. 3 Requirement number here is the production order number .If the order is > 10, then it truncated from right to left Requirement number is the production supply area , dynamic bin is not supported. The quantity to be staged is defined in the control cycle. Requirement number is the production supply area Dynamic bin coordinate not supported in manual staging 4 Can have one control cycle for all materials One control cycle per material per PSA.Here , one control cycle for multiple materials per PSA does not work. Need to have control cycle for each material .Due to system performance you can create one control cycle for multiple materials Can have one control cycle for multiple materials per PSA. 6
- 7. Production Supply Area • PSA lies in the production area. It is in the PSA that the material staging is done • PSA groups together the work centers near to production storage bins, taking the material staging type into consideration. • A PSA area is defined per plant and storage location under for a warehouse number under WM- PP Interface. Transaction for Creation :PK05 Standard Production Supply Area: 100-Production Supply Area 7
- 8. Production Supply Area Determination Work Centre Master Data • If no information is maintained in the work center the system checks in BOM Bill of Material (BOM) • If no information is found in the BOM , then the system check for source supply area in the material master data Material Master Data 8
- 9. Movement Type Determination • The system will first which Storage type is assigned in the control cycle. For eg.100 Control Cycle • To the storage type a replenishment movement type is assigned ,and hence the system determines the movement type. For e.g.-319 –Replenish for Production Storage Type 9
- 10. Production Storage Bin • A production storage bin is a storage bin in the PSA. • A production storage bin , is used in the control cycle for each material and PSA. This helps the system to understand the bin where the material will be staged. • It is created as a normal bin. • You can have dynamic bins for Pick Parts, and the staging will be done for particular orders. 10
- 11. Process Flow Process Order Release Order Material Staging manually/Automa tic A Transfer requirement is created with requirement type “p” With reference to the TR a TO is created via LB13.TO Creation can be manual/automatic GI for the material consumption The following depend on the settings in the production schedule profile: 1. Automatic/Manual Staging 2. Transfer requirement/delivery creation upon release • WM is responsible to provide materials for production. • It does so by supplying the needed materials to storage bins to production area. • This is done so through creation of transfer orders for every transfer requirements. • The subsequent goods issues posting reduces the stocks that have been removed from “production” storage bins ,and no additional activities are required in WM Material will be staged in 100 –Production Supply Area 11
- 12. Interface Active V/s Interface In-Active 12 Sr.No WM-PP Active WM-PP Inactive 1 Once order released , staging needs to be carried out No Staging required. 2 Control cycles required Control Cycle not required 3 PSA area and production storage bins required PSA and bins not required 4 319/320 movement type used for staging These movement types are not used 5 Upon goods issue , material gets consumed and no additional activity required in WM Upon goods issue, materials gets consumed in IM, in WM TR and TO needs to be processed and confirmed to clear the negative quants. 6 PSA -100 used here 914- Goods in Production Area is used
Editor's Notes
- #5: In case of WM-PP interface not active , the following is the process flow: 1.Creation of Production/Process Order 2.A goods issue is created with reference to a Process Order. This is a material document with Movement Type:961 3.The material document generates a TR which causes the stock to move to interim storage type 914- Goods Issue to Production Area. This causes a negative quant to be created in the interim storage type 4.With reference to a TR a TO is created. 5. On confirmation of the TO the negative quant is cleared ,and this ends the process.
