Migrate Warehouse Products
Application component: Interface ERP
App type: SAP GUI
Description: You can use this function to migrate warehouse product data and some warehouse-independent product data from LE-WM into SAP S/4HANA Supply Chain for Extended Warehouse Management (EWM). The following options are available when migrating data:  Migrate product master data Migrate fixed bin assignmentsIn EWM, you can create fixed bin assignments which are stored in a separate table (/SCWM/BINMAT).  Migrate palletization dataIf the master data of the migrated products in SAP S/4HANA includes palletization data, you can transfer this data into EWM in the form of new packaging specifications. A separate packaging specification is created for each product. The data is stored in a sequential text file, which is passed to the transaction /SCWM/IPU for upload.  Migrate warehouse management unit of measure (UoM)You can migrate the warehouse management UoM from material master data and use it to create a packaging specification in EWM for warehouse task creation. The data is also stored in the sequential text file which is passed to the transaction /SCWM/IPU for upload.     
Key features:  You can use the same tools for download from LE-WM and upload into EWM. The sequential files can be stored either locally on your PC or as a logical file on the server. You must specify the source system and client in the field ERP Business System. You can restrict the entries that are read from the S/4HANA system, selecting by S/4HANA warehouse number, storage type, and product number. If you want to read plant-specific data, you must enter an S/4HANA plant. Recommendation You should only enter an S/4HANA plant if you want to migrate the MARC fields MARC-ABCIN (Cycle counting indicator) and MARC-EPRIO (Stock determination group), because the additional selection might slow down the report runtime. If you only want the warehouse-specific data, you can leave the S/4HANA plant selection parameter empty.  For fixed bin assignment, the same logic can be applied as is available for storage bin migration in general. This means that you can assign the storage type to the storage bin name in Customizing, either with or without a special separator. To assign a storage type to a storage bin, go to Extended Warehouse Management  Interfaces  Migration from LE-WM  Assign Storage Type to Storage Bin in Customizing. When uploading and downloading, you can choose to migrate the data of the product master records, the fixed bin assignments, the packaging specification creation data and/or the warehouse management UoM separately. The product data and fixed bins are stored in the same sequential CSV file, whereas for the palletization or warehouse UoM data the system creates a text file. This is necessary because the packaging specification upload is carried out using the transaction /SCWM/IPU, which requires a text file. You can manually change the Entitled to Dispose field. By default it is set by the S/4HANA plant (if given) or the warehouse number default values in EWM After downloading, you can display the product data records in an ALV list. When uploading, you can update the product master data again, create fixed bin assignments, or upload the palletization data separately or in the same run. To check the data for the product master after uploading, you can use the transaction /SCWM/MAT1. You can display a list of the fixed bin assignments with the transaction /SCWM/BINMAT. If packaging specifications are created, the numbers of the created specifications are shown in a protocol at the end of the upload. Using the numbers (or other selection parameters such as the creator’s name or creation time), you can select the packaging specifications in the transaction /SCWM/PACKSPEC. To use the created packaging specifications, you must first have selected and activated them. To delete warehouse number or storage type-specific product master data, you can use the existing transaction for changing master data. You can find this transaction on the SAP Easy Access screen under SCM Basis  Master Data  General Master Data Functions  Mass Maintenance or by using the transaction MASSD. Here you can initialize the relevant fields. The warehouse number and storage type views are not completely deleted. To delete assignments of fixed storage bins, you use the existing transaction for mass deletion. You can find it in the launchpad under Extended Warehouse Management  Master Data  Storage Bin  Delete Fixed Storage Bin Assignment or by using the transaction /SCWM/RFIXBINDEL. To delete the created packaging specifications, run the transaction /SCWM/PACKSPEC, select the packaging specifications, and delete them. For the warehouse management UoM, the system decides which unit should be used according to the rule given in the field Propose UoM From Mat in S/4HANA Warehouse Management General Data. For example, the value ‘ ‘ in this rule indicates that the basis UoM should be the warehouse management UoM. If the chosen field for the warehouse management UoM is initial, the system reads table T340D and decides on a UoM according to rule 1 in this field. If the UoM is still initial, the system does the same with rule 2. These two rules are exactly the same as those in Propose UoM From Mat, but are the default values on warehouse level in S/4HANA.  The following fields are transferred from LE-WM: Product Master Data, Warehouse Level  LE-WM  EWM  Description     MLGN-MATNR  EXT_MATNR  Material/product number    MLGN-LGNUM  LGNUM  Warehouse number    MLGN-LGBKZ  LGBKZ  Storage section indicator    MLGN- LTKZE  PUT_STRA  Storage type indicator for stock placement    MLGN-LTKZA  REM_STRA  Storage type indicator for stock removal    MLGN-BLOCK  BLOCK  Bulk storage indicator    MLGN-BSSKZ  PTDETIND  Special movement indicator for warehouse management    MLGN-L2SKR  L2SKR  Material relevance for two-step picking    The following items of palletization data do not have a 1:1 relationship between S/4HANA and EWM. They are transferred into an EWM packaging specification.   LE-WM  Description     MLGN-LETY1  Higher level storage unit type used for palletization    MLGN-LHMG1  Packed quantity on higher level storage unit type    MLGN-LHME1  Unit of measure of the packed quantity    MLGN-LETY2  Middle level storage unit type used for palletization    MLGN-LHMG2  Packed quantity on middle level storage unit type    MLGN-LHME2  Unit of measure of the packed quantity    MLGN-LETY3  Lower level storage unit type used for palletization    MLGN-LHMG3  Packed quantity on lower level storage unit type    MLGN-LHME3  Unit of measure of the packed quantity    Product Master Data, Storage Type Level  LE-WM  EWM  Description     MLGT-LGTYP  LGTYP  Storage Type    MLGT-NSMN  REPQTY  Replenishment quantity    Fixed Bin Assignment  LE-WM  EWM  Description     MLGT-LGPLA  LGPLA  (Fixed) storage bin    MLGT-LPMAX  MAXQTY  Maximum storage bin quantity    MLGT-LPMIN  MINQTY  Minimum storage bin quantity    Product Master Data, General Level  LE-WM  EWM  Description     MARA-MHDRZ  SLRQ_MIN  Required minimum shelf life    Product Master Data, Plant Level  LE-WM  EWM  Description     MARC-ABCIN  CCIND  Cycle counting indicator    MARC-EPRIO  STCKDETGR  Stock determination group    All quantities are transferred and stored using the material's base unit of measure. Warehouse Number, Product Number, Entitled and other fields are represented in the file with the EWM values. The product number in the file for the packaging specification upload is an EWM product number. Additional data in this file is either taken from the mapping that you have specified in the transaction /SCWM/MIG_MAP_SUT, or from the packaging specification Customizing (such as the level type names assigned to the level set used, which in turn is assigned to the packaging specification group).
