¿Qué causa este problema?

This error message appears in the following situation:
You want to post several goods movements at the same time in different
storage locations. In other words, the
<DS:GLOS.3526C023AFAB52B9E10000009B38F974>material document</> to be
posted has several items. According to the system,
<DS:GLOS.35CEB720B3CC735DE10000009B38F982>Handling Unit Management</> is
active in at least one of these storage locations. Whether an item is to
be processed using <DS:GLOS.3618AA32895864D8E10000009B38F985>handling
units</> (HU) or not, depends on the storage location.
For the goods movements you want to post, the following cases are
possible:
The first item refers to a storage location subject to a HU. One of the
following items is to be posted in a storage location that is not
subject to a HU.
The first item refers to a storage location that is not subject to a HU.
One of the following items is to be posted in a storage location subject
to a HU.
In both cases, there is a situation in the document to be posted that is
not clear.
For goods movements in a storage location that is not subject to a HU,
the system wants to create a material document.
For goods movements in a storage location subject to a HU, the system
wants to create a <DS:GLOS.3526BEB2AFAB52B9E10000009B38F974>delivery
</>.
The system, however, can only create a material document <ZH>or</> a
delivery. It is not technically possible to create two documents at the
same time. The item created first determines whether the complete
document is subject to a handling unit or not.

Respuesta del sistema

As the situation is unclear, the system cannot post these goods
movements.

Procedimiento para Administradoras de Sistemas

You can set this message in Inventory Management Customizing under
<ZH>Define Attributes of System Messages</>. If you change the message
status to <LS>W</> (warning), the system creates a delivery. <ZH>All</>
items are therefore copied into a delivery, including those that are
usually posted with a material document. This is necessary, as at least
one item requires a delivery because of the HU obligation, and the
system can create only one type of document at the same time. It is
therefore obligatory in this case to create a delivery.
This is the only possible way of processing documents that are unclear.
A delivery is then always created for all items if at least one item
features a storage location subject to a HU.
<ZH>Note</>
Some transactions, such as the pick list (transaction CO27), call the
<DS:GLOS.3526B20FAFAB52B9E10000009B38F974>function module</>
<DS:FU.MB_CREATE_GOODS_MOVEMENT>MB_CREATE_GOODS_MOVEMENT</> to post the
goods movement. This function module only outputs error messages,
warning messages are not displayed. In this case, a delivery is directly
created without a warning message.
