Hi Experts! I'm an average BEX query user and recently I've been having an issue where I am attempting to update a restriction for "Calendar Day" that I had placed on a query I had built which has been working fine. My problem is if I try to update or change the restriction. The restriction is basic: I am using 0DAT-1 ((or Current Calendar Day (SAP Exit) -1)) When I try to update the restriction, I immediately get a pop-up error screen with three messages (which I've attached). My only option is to print a trace (which I've done and attached with the error message) and then click "Continue" which completely shuts down my Query Designer. All my SAP SMEs at work can tell me is that this has happened many times and that it could happen in some cases like when you are restricting on any value, if that particular InfoObject has huge range of F4 values, or when you are trying to write some complex logic in formula etc. None of those answers apply since I was able to initially restrict this particular value. Can anyone here tell me the "why" this is happening and what (if anything) can be done to fix this? As far as I know, it only appears to be happening for value 0DAT. ANY help or direction would be greatly appreciated as this is very frustrating.
