IDoc for Creating and Canceling Transfer Requirements (SAP Library

IDoc for Creating and Canceling Transfer Requirements

Definition

Using IDoc WMTRID01, you can send data on transfer requirements from the external system to the Warehouse Management system (WMS), so that the WMS can create TRs on the basis of the data. You can also use the IDoc to cancel TRs that have already been created in the WMS.

Recommendation

We recommend simulating construction and sending of the IDocs to the WMS in order to test the relevant activities. Report RLTREQ00 is available for the test.

Use

Creating Transfer Requirements

Take the following into account when creating transfer requirements via IDoc WMTRID01:

Segment E1LTRQH (IDoc header data)

Field	Note
TBNUM	You do not transfer the TR number, since the WMS issues the TR number
BETYP	You transfer this field if the movement type used expects a requirement number, in order to generate the link to the initiator of the stock movement.
BENUM	You transfer this field if the movement type used expects a requirement number, in order to generate the link to the initiator of the stock movement.
VLTYP	You use this field to define the source of the stock movement.
VLPLA	You use this field to define the source of the stock movement.
NLTYP	You use this field to define the destination of the stock movement.
NLPLA	You use this field to define the destination of the stock movement.
PDATU	You define when the TR should be converted to a TO.
PZEIT	You define when the TR should be converted to a TO.
LZNUM	To keep the TR clearly identifiable from the point of view of the external system, the external system assigns a reference number and transfers this to the WMS. You can only cancel TRs in the WMS from the external system via a unique reference number.
TBRUE	This field is designed for customer modifications in case confirmation of processed TRs to the external system is required.

E1LTRQI (IDoc item data)

Field	Note
ABLAD	You define the destination of the goods movement for individual items in the TR.
WEMPF	You define the destination of the goods movement for individual items in the TR. You generate a transfer requirement (TR) in order to stage several materials for a production order within production. You define the production storage type in the transfer order header. However, you define the work center where the material is to be staged for each individual TR item. You enter the individual work centers in field WEMPF.
WENUM	You use this field if you want to send notification of a goods receipt or plan a goods receipt with the TR.
WDATU	You use this field if you want to send notification of a goods receipt or plan a goods receipt with the TR.

Canceling Transfer Requirements

Take the following into account when canceling transfer requirements (TRs) via IDoc WMTRID01:

E1LTRQH (IDoc header data)

Field	Note
LGNUM	Required entry
LZNUM	Required entry

E1LTRQI (IDoc item data)

Field	Note
TBPOS	The external system does not transfer any TR item numbers during creation of TRs in the SAP system. The SAP system assigns the TR item numbers on creation of the TR. The system cancels TRs item by item. The external system must therefore transfer the TR item number of the TR item that is to be cancelled. If the number is know in the external system, the entire quant ID of a TR item must be transferred to the SAP system with the IDoc. In this case, you must fill fields MATNR, BESTQ, CHARG, SOBKZ and LSONR.
ELIKZ	This indicator must be set if the TR item is to be completely cancelled. If you only want to cancel a partial quantity of the item, transfer the quantity to be cancelled. To increase the quantity of an item, transfer a negative quantity for cancellation. You transfer fields MENGE and MEINS.

Structure

Message Type

You define message type WMREQ for the inbound partner profile.

Note

The external system may also have to transfer other data, as well as the required entries. The extent of the IDoc data that is required depends on the type of requirement (for example, putaway from production or staging for production) and above all on the entries and settings in the WMS.
