IDoc for Canceling Transfer Orders

Definition

Using IDoc WMCAID01, you can send a cancellation request to an external system, or confirm execution of a cancellation movement to the Warehouse Management system (WMS).

Use

When physical stock movements are executed via the connected external system, the WMS cannot determine whether the TOs transferred to the external system have already been executed. For this reason, the WMS can only send a cancellation request to the external system.

The external system then decides whether or not the movement has already been executed. If the stock movement has already been executed, the external system confirms to the WMS that the stock movement has already been completed and that cancellation is therefore no longer possible. In this case, the user receives a corresponding message in the WMS.

You decide for each individual case what should happen with a TO item that cannot be cancelled. In this case, you make the necessary adjustments manually in the system.

Note

You can only cancel these transfer orders (TOs) if they have not yet been confirmed.

Sending a Cancellation Request from the WMS to the External System

To send a cancellation request from the WMS, fill the following fields in IDoc WMCAID01:

Segment	Field
E2LTCAH	LGNUM
	TANUM
	CANRQ
E2LTCAI	TAPOS
	VLENR (if SU-management is active)
	NLENR (if SU-management is active)

Sending a Cancellation from the External System to the WMS

To send a cancellation of a TO to the WMS, fill the following fields in IDoc WMCAID01:

Cancellation is possible

Segment	Field
E2LTCAH	LGNUM
	TANUM
	CANCL
E2LTCAI	TAPOS

Cancellation is not possible

Segment	Field
E2LTCAH	LGNUM
	TANUM
	CANCL
E2LTCAI	TAPOS
	SFEHL
	SFTXT

Note

You can also cancel a transfer order from the external system and send the cancellation to the WMS, even if the WMS has not sent a cancellation request first.

Recommendation

We recommend that you simulate sending a cancellation reply from the external system to the WMS, in order to test the relevant cancellation processes. Reports RLCATO00 and RLCATO10 are available for testing cancellation.

Structure

Message Type

You define message type WMCATO for the inbound and outbound partner profile.

Segments

IDoc WMCAID01 is made up of two segments:

E2LTCAH (TO header data)
E2LTCA (TO item data)

Segment definition E2LTCAH001 (as of release 4.0A)

Field	Data Type	Description	Required Entry	Note
LGNUM	CHAR 3	Warehouse number	X
TANUM	CHAR 10	Transfer order number	X
CNAME	CHAR 12	User name for TO cancellation
CANRQ	CHAR 1	Request cancellation transfer order	X	X for cancellation request
CANCL	CHAR 1	Response cancellation transfer order	X	X for cancellation from external system
SOLEX	CHAR 15	Target processing time from external system		The system resets the target processing time when you send a cancellation request If you cancel the TO via the IDoc, you can transfer the target processing time determined by the external system to the TO

Segment definition E2LTCAI (as of release 3.0A)

Field	Data Type	Description	Required Entry	Note
TAPOS	CHAR 4	Transfer order item	X
VLENR	CHAR 20	Source storage unit number	X
NLENR	CHAR 20	Destination storage unit number	X
SFEHL	CHAR 1	Error during cancellation
SFTXT	CHAR 80	Error text for cancellation		This text appears in the inbox for error messages
KZFOL	CHAR 1	Indicator: Subsequent actions		You can use this field individually, for example to trigger a user-defined process via a user exit. You can, for example, trigger a user-defined follow-up action for differences.
