Several IDocs are available for confirming a transfer order (TO) from the external system to the Warehouse Management system (WMS).

• WMTCID01 (as of release 3.0A)
• WMTCID02 (as of release 4.0)
• WMTCID03 (as of release 4.6C)

Using these IDocs, you confirm transfer orders that have been executed to the WMS. Based on the confirmed data, the WMS confirms these TOs.

When sending the TO data, the WMS first transferred the data which requires confirmation in IDoc WMTOID01 or WMTOID02 in segment E1LTROI with field KZQUI to the external system.

If you work with storage units (SUs) in the warehouse and you move the entire storage unit, you confirm one transfer order for the entire SU for this stock movement.

If a storage unit with mixed storage is involved and you move individual materials from it, there are several transfer orders for this storage unit. You confirm the corresponding transfer order for each stock movement.

If you determine that there are differences in the SU when you execute the TO, confirm the entire storage unit and enter the difference quantities for the items for which differences occurred.

For stock removals, you normally confirm entire transfer orders.

For putaways, you can confirm TOs item by item if you put away several pallets with one TO.

If you confirm entire TOs, you can enter differences for individual TO items.

You confirm performance data (actual TO processing time) to the WMS via segment E1LTCOG. Normally, the WMS determines the planned TO processing time and adds to this the planned processing time reported by the external system.

You can also report the actual data to the WMS independently of the confirmation, by only sending segment E1LTCOG.

You can report actual data if the transfer order data was transferred to the external system with the value 2, 3, or 4 for indicator KZLEI in IDoc WMTOID01 or WMTOID02.

Depending on the value of indicator KISTZ in IDoc WMTOID01 or WMTOID02, you confirm the actual data in segment E1LTCOG as follows:

If you determine during a stock movement that a difference exists, transfer these references via IDoc WMTCID03 in segment E2LTCOI000, by filling the following fields:

To confirm differences to the WMS, use case 3, 4, or 5.

For confirmation with zero stock check, use case 3 or 4.

For stock removal from a storage type with zero control, you must explicitly confirm the bin, which has become empty as a result of the confirmed stock movement.

If the indicator KZNKO was set for the stock movement in IDoc WMTOID01 or WMTOID02, IDoc WMTCID03 must confirm the zero stock check to the WMS in segment E1LTCOI.

If the storage bin is empty following the stock removal, set the indicator KZNUL in the IDoc.

If there is a remaining quantity in the storage bin, transfer the following fields in segment E1LTCOI:

Even if the zero stock check was not required, the external system can confirm the zero stock check to the WMS if the storage bin becomes empty as a result of the stock movement. In this case, the physical stock level differs from the stock level in the system. For this, you set indicator KZNKO in IDoc WMTCID02.

If, during goods movements, you confirm batch-managed material in SU-managed bulk storage or in a warehouse with lean WM, you transfer the batch number of the materials that have been removed with the confirmation data. To do this, you use field CHARG in segment E2LTCOI004 (confirm batch for lean WM or bulk storage).

You confirm the storage units (SUs) that have been removed to the WMS along with the confirmation of the transfer order.

When confirmation of the individual SUs is complete for a TO item, set the field BQUIT in segment E1LTCOI.

In this case, you confirm the TO item by item (see case 4). This means that there can be several TO items per confirmation. Only one confirmation is permitted per storage unit withdrawn.

If you confirm transfer orders for a bulk storage type with mixed storage, you must transfer the quant data to the WMS for the material that has been moved. The WMS can only confirm the transfer order if the goods movement is clearly assigned to certain quants.

• You can determine the quant number of the material that has been moved via user exit MWMIDI02 and confirm this to the WMS.
• If the quant number of the material that has been moved is known in the subsystem, transfer this quant number to the WMS by adding a "Quant number" field to segment E1LTCOI for the confirmation.

If you use lean WM, we recommend confirming the quant number to the WMS, since no quant data is known in a warehouse with lean WM.

• In this case, we recommend transferring the batch number of a material with batch management during the confirmation of a goods movement to the lean WM.

• To confirm movements of consignment stock in lean WM, transfer the fields SOBKZ (with the value K) and SONUM (the special stock number of the vendor).

You define message type WMTOCO for the inbound partner profile.

The IDoc for transferring confirmation data is constructed as follows:

• WMTCID01 (as of release 3.0A)

• E1LTCOX: Confirm entire storage unit
• E1LTCOH: Confirm TO header
• E1LTCOI: Confirm TO items

• WMTCID02 (as of release 4.0)

• E1LTCOX: Confirm entire storage units
• E1LTCOG: Reporting performance data via confirmation
• E1LTCOH: Confirm TO header
• E1LTCOI: Confirm TO items

• WMTCID03 (as of release 4.6C)

• E1LTCOX: Confirm entire storage units
• E1LCOSE: Confirm with serial number
• E1LCOHU: Confirm HU data per TO item
• E1LTCOG: Reporting performance data via confirmation
• E1LTCOH: Confirm TO header
• E1LTCOI: Confirm TO items
