One- and two-step picking
for shipping with mobile dialogs
Customer: CTDI GmbH
Project duration: 6 months
CTDI is the world’s largest independent after-sales service repair and logistics provider for customers in the communications, IT, automotive and B2B industries. More than 14,000 employees at over 90 locations manage almost the entire range of technologies. In Europe, the CTDI Group has more than 20 locations in 15 countries. CTDI offers operators and manufacturers national and international services from a single source.
CTDI works with two different picking systems. A subsystem was used that communicates with the central SAP systems via an RFC interface. The system is connected via IDocs. The subsystem leaves the prioritization and picking waves to the discretion of the shift leader. Processing is done manually.
The second picking system works directly in SAP via a TelNet connection with specially programmed Z programs and has been in use since 2005. The transfer orders are confirmed in the SAP system during picking at the storage bin, while with the subsystem the transfer orders (TO) are confirmed as soon as they are created.
The interfaces between the systems repeatedly cause problems during order picking. It is also difficult to carry out a serial number comparison. Plausibility checks and traceability are only possible with great effort, as the data from the various systems must be reconciled here. In the future, a uniform mobile solution with the following options is to be created:
