What causes this issue?

The syntax check found an error in an action or procedure. No inference
of values values is formulated (in connection with a table/function
call).

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Qualify all characteristics for which you require inferred values with
$SELF. For example:
TABLE TEST_TAB(COLOR = 'red', PRICE = $SELF.PRICE)
If you enter:
TABLE TEST_TAB(COLOR = 'red', PRICE = PRICE)
no value is inferred for characteristic PRICE.
Check whether the values you want to infer match the value assignment
alternatives defined in the table. In actions and procedures, the first
value assignment alternative defined for a table access is read. You
can only infer values for characteristics that are defined as data
fields in the value assignment alternative. If a characteristic is
defined as a key field in a table, values cannot be inferred for this
characteristic.
