• Message number: 046

• Message text: Wrong status in database! Material & or & not unique

What causes this issue?

It has been determined that a material that has to be converted appears

are therefore partly incorrect.

System Response

The system could not completely activate/deactivate the MPN conversion.

How to fix this error?

Change the material master of the material specified in the message.
Change the MPN or enter a new MPN (field MARA-MFRPN), or expand the
converted expression by adding an external manufacturer (field
LFA1-EMNFR).
If this does not work, go to table MATERIALID using transaction SE16,
and search for duplicates in the primary key MATNR_INT and in the
secondary key MATNR_EXT, and change them, where necessary.
Then, repeat activation/deactivation.
