Problem Events DQL

Guys, can you help me with the case below?

I need to get only active (open) problems. This is happening, however, I am not able to bring the tags I need. As I'm getting takeMax, I think it's not returning the information. Can you help me adjust this query? I've done several tests and haven't been able to improve.

I have several tags, I want to specifically get the defined value.

Thank you

what are you trying to achieve by using takemax?

@FranciscoGarcia I'm trying to get the last recorded event. I've already used takeLast, takeFirst. takeMax was the one that best suited my needs.

I think the issue is in the parse command. Can you try chaning the double quotes to single? . Ie: Change

| parse entity_tags, """ "Jornada:" DATA:Jornada """

 to 

| parse entity_tags, """ 'Jornada:' DATA:Jornada """

@FranciscoGarcia 

That's not it... I have my dashboard using these double quotes and the Parse is done correctly. What is happening is that in the code below, at times, especially when I increase the period in the timeframe, for example 24h, 6 hours, Dynatrace returns events with OPEN status when in reality they are no longer open. I'm trying to adjust this. I need Dynatrace to return only open problems, get the last event.

You are right. The quotes are OK. Just and idea, not sure if it will help you. Usually to get the latest open problem I use something like: 

fetch events
| filter event.kind=="DAVIS_PROBLEM"
| dedup display_id, sort:{timestamp desc} // only select most recent problem event
| filterout event.status=="CLOSED" // keep open problems
