How To Fix EPROD058 - Key for attribute EQUNR cannot be transferred

EPROD058 - Overview

• Message type: E = Error

• Message class: EPROD - Messages for IS-U Master Data Templates

• Message number: 058

• Message text: Key for attribute EQUNR cannot be transferred

What causes this issue?

You are using a master data template in which a node of the DEVICE_INFO
category is used to create a device info record. As of Release 4.64,
the master data template category belonging to this node contains an
attribute called EQUNR. This attribute can be used to inform the
subsequent node (for example billing-related device installation) about
the newly created device info record.
However, when the master data template was executed, the system
diagnosed that EQUNR does not exist. The reason for this is that the
master data template was create while you were running a previous IS-U
release and was not changed when you upgraded to IS-U 4.64. The master
data template therefore does not recognize the new EQUNR attribute.
You can continue using the master data template. However, we recommend
that you update it. You do this as follows:
Call transaction EPRODCUST. Enter the key of the master data template
and choose the <ls>Change</> button.
Save the master data template. It now contains the new attribute.
The EQUNR attribute was introduced in Release 4.64 because this release
enables you to create several device info records for a device number
and material. If you use this functionality, ensure that you use the
equipment number for logical device installations since this number is
unique. Change your master data templates accordingly.
