How To Fix DB771 - Selection criterion "&1" contains an invalid selection line

SAP Error Message - Details

• Message type: E = Error

• Message class: DB - Messages for logical databases and background processing

• Message number: 771

• Message text: Selection criterion "&1" contains an invalid selection line

What causes this issue?

Although selections exist for the selection criterion "&V1&", they can
be processed neither on the selection screen nor on the 'Multiple
selection' screen because of restrictions in the application program.
The line in question has the sign "&V2&" (field SIGN) which is not
allowed on the main selection screen. Since the selection option (field
OPTION) "&V3&" is allowed neither on the main selection screen nor on
the 'Multiple selection' screen, the line cannot be displayed.
There is probably an error in the application program.

System Response

The processing had to be terminated.
