How To Fix TB527 - Only right-generic key patterns possible

TB527 - Overview

• Message type: E = Error

• Message class: TB - SM31 table maintenance messages

• Message number: 527

• Message text: Only right-generic key patterns possible

What causes this issue?

In order to restrict the comparison to a manageable number of view
entries you can specify a right-generic key pattern. This means that
you may only use the generic character '*' as the last character of the
whole key pattern. The whole key pattern emerges when you write the
contents of the individual key fields behind each other.
Note that an empty field of the whole key pattern before the generic
character is interpreted as a sequence of blank characters and not as a
place holder for arbitrary characters. In order to select all view
entries enter the generic character '*' in the first (non-numeric)
field. No generic entry is possible in numeric fields and date fields.
