IDoc for Confirming Warehouse Tasks 

Definition

You use IDoc /SCWM/WMTCID01 to send confirmations from the non-SAP system to Extended Warehouse Management (EWM).

Use

You use this IDoc to report executed warehouse tasks (WTs) to EWM. EWM uses this reported data to confirm this WT.

Prerequisites

In Customizing for Extended Warehouse Management, under Master Data → Define Storage Type or Cross-Process Settings → Warehouse Task → Define Warehouse Process Type, you have specified which warehouse tasks are subject to a confirmation requirement.

When sending the WT data, EWM previously transmitted the data for the confirmation requirement in IDoc /SCWM/WMTOID01 in segment /SCWM/E1LTROI with field KZQUI to the non-SAP system.

Confirmation of Handling Units

If you work with handling units (HUs) in your warehouse and move the entire handling unit, then you for this stock movement you confirm a warehouse task for the entire HU.

If the HU is a mixed HU and you move individual products, then there are several warehouse tasks for this handling unit. You confirm the relevant warehouse task for each stock movement.

During execution of the warehouse tasks, if you notice differences in the handling unit, then you confirm the entire handling unit and enter the difference quantity for those items where you noticed a difference.

Confirmation Without HU Management

For stock removals, you confirm entire warehouse tasks.

For putaway, you can confirm the WTs item by item, if you are putting away several pallets in your warehouse using one warehouse task.

During confirmation of entire WTs, you can enter differences for individual WT items.

Confirmation of Products Managed in Batches

If you confirm batch-managed products during goods movements in a HU-managed bulk storage type, you transmit the batch number of the removed products with the confirmation data. You use the CHARG field (report batch for bulk storage) in segment /SCWM/E2LTCCOI004.

Confirmation in a HU-Managed Bulk Storage Area

You report the picked HUs to EWM when you confirm the warehouse task.

If the reporting of individual HUs is completed for a WT item, set the BQUIT field in the segment /SCWM/E1LTCOI.

In this case, you report the WT item by item. There can be several reports for each WT item. Only one report is allowed for each picked HU.

If the products are managed in batches, then you transfer the batch number of the products moved when you transfer the confirmation data. You use the CHARG field (report batch for bulk storage) in segment /SCWM/E2LTCCOI004.

Structure

Message Type

You define the partner agreement inbound for message type /SCWMWMTOCO.
