Hi guys, why when I try to create a rule input in expression rules editor, it told me  could not find the variable? 

Hello Appian Comunity, Can you pls let me know and explain which is the proper expression rule when configuring the visibility field for the " only show when " option on the record type object? What I´d like to do is to show the image of the car when available. As I have it right now it doesn´t show the image on the record list. also, can you pls help me understand why if I have the following configuration on the display value, and on the visibility, field selected " always show " I get the error?  Thanks a lot.

Hi everyone, I'm filtering this record to only query cases with completed date within nearest 5 days. My query code is as below: a!queryFilter( field: recordType!Record.completedDateTime, operator: ">", value: datetime( year(now()), month(now()), day(now()) - 5, 00, 00, 00, 00 ) ) The code worked well last week, but this morning it suddenly showed this error:  The Requested Record Type Is Not Available The default filters expression for record type failed to evaluate. Details: [Expression evaluation error at function a!queryFilter [line 4]: Date out of range: Invalid day]. (APNX-1-4205-018) I've checked the DB and data for this column was the same structure as last week:  datetime /* mariadb-5.3 */ . For example: 2022-08-01 04:14:49.  Any one has faced the same error code? Please give me some suggestion if possible...  Thank you!

Hello We have recently upgraded to 22.3 on-premise installation and using SQL server as data source. In the new release of 22.3 its mentioned you can create New Data Model in Record page and design the columns within the Record itself. However, this option isn't available in our environment (link below). see attachment/resized-image/__size/320x240/__key/communityserver-discussions-components-files/16/Screenshot-2022_2D00_08_2D00_29-105432.jpg My question is, is such feature is available only for Cloud customers or there additional configuration is required to see such option. Best regards, Khaled

Hi Team, We have a grid which shows data from record type where we pull data from DB table. We have a column which is integer in DB table but in the grid we have shown the value with a text prefix. We want to search the grid with the value shown in grid. Example -- In table the value is stored as 123, we are showing in grid as TXT123. I want to search the grid with the value "TXT123". While searching it does not show any value but with 123 it returns me the row. Please let me know if we can search the grid with value TXT123 and how to do it. We would want inbulit feature of Appian grid search. Thanks in advance

Hi All, I am using an existing table which is having around 61 lakh something data as a source to my record. There is no particular source filter to add so I have added filter to my primary key to display record within appian's sync limit. But while I am using search Text in record I am not getting the value which is beyond the source filter limit. Is there any solution to overcome this issue. Thanks & Regards, Kavya

Hi, we use a query entity to retrieve decimal numbers to check data inserted. After testing, we see that Appian have a strange behaviour with decimal digits, according to the integer digits of the number.  For example, when we insert a number with 5 integer digits, it shows 2 decimal digit, while, when we insert a number of 6 integer digits, it shows 1 decimal digit. With 7 (or more) integer digits, no decimal digits are visible.  This is not a DB problem, because, if I use an expression rule, with a conversion on decimal number, I get the same problem. Here some examples: I try also "fixed" function, but sometimes it doesn't works. Is there a workaournd to get the right value?  Thanks. Regards. Juri Monti

I just wanted to delete certain transactions from the table after 30days.

Hi All,         We were using an entity backed record previously but the search filter is not working for that case. It is a view from DB so we directly use that as a DB source also we disable the sync option to get view as source. Now we are facing filter and sorting issues. Can anyone suggest solution for this. when user pick a value in search field it is not available for display but it is available in view. Is there anyway we can apply source filters but search field filter will work to all values. Thanks & Regards, Kavya
