• Message class: MG - Batch input: material master

• Message number: 303

• Message text: Enter values in the new fields prior to the next release upgrade

What causes this issue?

The <DS:GLOS.sequential_file>sequential file</> to be processed
contains shorter records than defined in the current release. The file
was not therefore created with the structures (such as BMMH1, and so
on) contained in the current release.

System Response

The NODATA character is entered in the new fields not containing an
entry in the current release. This is to prevent any field values not
already maintained from being inadvertently overwritten in change mode
by the <DS:GLOS.initial_value>initial value</>.

How to fix this error?

Be sure to create the sequential files with the current transfer
structures.
