Diagnosis
Your intervals do not have any obvious properties that are not allowedfor analysis authorizations.
Intervals are corrected by the system within a very narrow frameworkwhen it is obvious what is meant.
(This is in no way a guarantee of correctness)
The desired format for normal characteristics is:
Single value: I EQ A (characteristic value =A),
Interval: I BT A B (A <= characteristic value <= B)
Sample: I CP A* and I CP A+ (Sample with any number (*) or exactly onecharacter (+) after A).
For the validity of authorizations, also excluding signs and thefollowing other relational operators are permitted. These are thenconverted to real intervals with interval limits 1/1/1000 and 12/31/9999EQ, BT, GT, GE, LT, LE, CP.
Absolutely not allowed: NE, NP, NB
Exit variables can be entered starting with $ (If a variable valueoccurs both in the lower limit and the upper limit, the two are combinedin the authorization processing as subnames of a total variable).

Examples:
General characteristics:
I EQ A B -> I BT A B
I EQ A* -> I CP A*
For the validity (0TCAVALID) of authorizations
a) I BT 200+1231 -> I EQ 200+1231 (BT-> EQ)
b) I CP 2001++13 20011+14 -> I BT 2001++13 2001++14 (CP -> BT)
c) I CP 200+1015 -> I EQ 200+1015(CP->EQ)
Intervals are not corrected when changes to the values would be required, for example when the upper characteristic value is less than the lowercharacteristic value.
