Selection Direction: Here you can indicate whether you want to carry out a download step or an upload step and whether you want to use storage bin data and/or sortation data.

For the storage bin sortation data, the fields SORLP and REIHF are migrated from ERP. SORLP contains the sorting sequence of the cross-line stock put away process. REIHF contains the sorting sequence of the picking process. The storage type of the storage bin master is migrated as the activity area for the sorting table. The activities are taken from the customized activities in the warehouse which have the warehouse process category 8 (Cross-line stock put away) and 2 (Stock Removal). This means that you can have multiple lines in the local file for one storage bin.

The intermediate file in which data is stored is either a locally-stored CSV file or a logical file stored on the application server. The CSV file has a header line with short text of the fields and can be edited with Microsoft Excel or a text editor. Both files are based on the structure /SCWM/S_LAGP_LSMW_MIG. In the CSV file, the fields are separated either by a semi-colon or a colon. The fields in the server file are not separated and there is no header line. The name of the CSV file always has the extension ‘.csv’. The file type of the server file is taken from the setup of the logical file name. During the data migration, the system ignores the first line of the CSV file, as it typically contains the column headers.

In LE-WM the table LAGP is read using the selection criteria you have entered. In EWM the storage bin data is stored in the table /SCWM/LAGP and the sortation data is stored in /SCWM/LAGPS. No other tables are affected.

In LE-WM the sorting fields can contain alphanumeric values, whereas this is not possible in EWM. If the system identifies alphanumeric values during download, it automatically resorts the affected activities in the activity area. If your sorting fields contain alphanumeric values you must migrate all storage bins of a storage type at once. The resorting during a migration run always starts with the value 1. If you split your storage type the original sorting sequence gets lost, but if you migrate all bins in a storage type in one run, the system can resort correctly. The LE-WM and EWM systems should have the same codepage.
