Enquiry Fixed Selection Issue

Dears, I faced an issue in T24 I have an enquiry on application Customer.position When I check out the last updated version from Production and try to change in it’s fixed selection it gives a request timeout and I tried to authorize record through backend it gives an error also, If I tried to change any field except fixed selection it works normally. but if the change in fixed selection it gives an error, also If I try to force through jed and try to change the area It gives a request timeout and Fatal error ,, is anyone have an idea about this ? 

Thanks so much
 

Hi
what exactly you try to input as a fixed selection ?
 

I tried to add ‘SUB’ in limit.level fixed selection
Fixed selection restored from Production Area -> LIMIT.LEVEL EQ PRODUCT INFO NULL

I tried to change to
LIMIT.LEVEL EQ PRODUCT INFO NULL SUB

while Authorize the record it gives a system administrator Error or if I tried to deploy record on another area gives Error on backend

If any have a solution with this case kindly write to me

Thanks

Hi
you can try to use quotes; as:

Dear,
I tried to change it to be with quotes but Same case it gives a system administrator error

Strange.. Is it because "SUB" is there? 

I don't have a working system with me now; LIMIT.LEVEL - is this a core or a local field? Any limitations on its contents?

Also, take a look at all logs.
