How To Fix 28110 - Keyword RESTRICTION: expected

SAP Error Message - Details

• Message type: E = Error

• Message class: 28 - Configuration

• Message number: 110

• Message text: Keyword RESTRICTION: expected

What causes this issue?

The syntax check could not identify the mandatory restriction part of a
constraint. This may be because the keyword <ZH>RESTRICTIONS:</> was
not found, or was not recognized because it was in the wrong place.

System Response

In a constraint, the sections OBJECTS: and RESTRICTIONS: are mandatory.
As soon as you enter a keyword that cannot be interpreted or an
incorrect punctuation mark ('.', ';', ',', ':', and so on) after an
object, the system tells you that it expects the RESTRICTIONS: section.
The cursor shows where the error in your entry occurs.

How to fix this error?

Check your entries:
You may have entered an incorrect keyword under OBJECTS: or CONDITION:
that leads the system to assume that you want to make entries for
RESTRICTIONS:. Check the syntax and spelling of the keywords in these
sections.
If the keyword RESTRICTIONS: is missing or written incorrectly, correct
the error.
If the keyword is there, perhaps it could not be interpreted correctly.
This could be, for example, because the preceding expression was not
closed correctly. A section is closed either with or without a period.
Several object declarations are separated by commas. Several
characteristic declarations are separated by semicolons.
If you enter several expressions under CONDITION: or RESTRICTIONS:,
separate them with commas.
