Using functions


You can use functions in various places in Senta: 


In placeholders -- useful for formatting placeholders in special ways, e.g. by formatting text.

In date offsets -- handy for choosing dates in more complex ways, e.g. the earliest of two dates.


To test any function in Senta, you can use the expression tester.


Available functions

The following functions are available in Senta:


IF

IF/ELSE

FIXED

TRIM

LOWER

UPPER

EARLIEST

LATEST

MOD

RAND, RANDBETWEEN, CHOOSE

REMOVESPACES

SUBSTITUTE

DATEFORMAT

MONTH, YEAR, DAY


Any of the described functions must be enclosed within curly braces { } when used within a placeholder.


IF


Lets you put in different text, dates, numbers, etc. based on a condition.


IF (condition, value1, value2)


IF (client.taxnumber <> "", "We have your tax number on file.", "We do not have your tax number on file yet.")

IF (client.priority = 1, +3d, +2w)


The IF function supports the following operators: 


= equals

<> does not equal

!= (this is the same as the <> above)

< is less than

> is greater than

<= is less than or equal to

>= is greater than or equal to


Using IF functions with yes/no fields and tasks


You can also use an IF function to populate an email based on a yes/no field or task. This means that you can have a different value inserted into an email depending on whether yes or no has been selected. 


For example, if you have a yes/no field in your practice where you record whether your clients are based in the UK or not, you can use an IF function to send a custom email to your clients, based on whether they live in the UK or not.


The standard format of an IF function with a yes/no field is the following:


{IF (client.fieldreference, "option1", "option2")} , 


To break this down further:


client.fieldreference = the field reference used in the yes/no field

option1 = text that will be inserted based for a yes answer

option2 = text that will be inserted based for a no answer


For example if you are recording whether your clients are based in the UK or not, you could use the following IF function to populate an e-mail. In this case we use client.clientbase as our field reference:


{IF (client.clientbase, "UK resident", "non-UK resident")}


All of our _______________ clients are required to...


If the answer is yes, the e-mail will populate as:


All of our UK resident clients are required to...


If no is the answer, the e-mail will populate as:


All of our non-UK resident clients are required to...


IF/ELSE


You can now use the function {if}...{else}...{endif} which allows you to have two different options for text in your emails, for example:


{IF (client.clienttype = "Individual")} 

Your self assessment tax return is due...


{ELSE} 


Your corporation tax return is due...


{ENDIF}



CONTAINS


Allows you to insert set text if a specific term is used within a field.


IF (CONTAINS(client.software, "Xero"), "We will access Xero to retrieve your accounting records.","Please upload your records to the client portal as soon as possible.")


EMBEDDED PLACEHOLDERS


You can use placeholders in the format {client.title} within other placeholders.


IF (client.language = "French", "Je vous écris au sujet de votre entreprise {client.title}", "I am writing to you regarding your company {client.title}")


FIXED


Shows a number with comma-separated thousands and a fixed number of decimal places


FIXED (number, places)


FIXED (1000, 2) would show 1,000.00


It is important in any number fields in Senta to not include a comma e.g. £1234.56 rather than £1,234.56.


TRIM


Removes excess spaces from text.


TRIM (text)


TRIM("Hello    ") would not show the spaces after Hello.


LOWER


Changes text to lower case.


LOWER (text)


LOWER ("ACCOUNTS") would show "accounts"


UPPER


Changes text to upper case.


UPPER (text)


UPPER ("payroll") would show "PAYROLL"


EARLIEST


Picks the earliest of two dates.  The two dates can be field references or date offsets.


EARLIEST (date1, date2)


EARLIEST (job.previous_task_completion, duedate-30d)


LATEST


Picks the latest of two dates.  The two dates can be field references or date offsets.


LATEST (date1, date2)


LATEST (job.previous_task_completion, duedate-30d)


MOD

Returns the modulus (remainder) when diving two numbers.  


MOD(dividend, divisor)


E.g. MOD(7, 3) would return 1; MOD(9,3) would return 0.


RAND, RANDBETWEEN, CHOOSE


Useful for generating random numbers, for example these can be used to randomly assign clients to an account manager.


RAND() gives you a random number greater than or equal to 0 and less than but not equal to 1.


RANDBETWEEN() gives you a random integer between your two values, inclusive, i.e. greater than or equal to the first number, and less than or equal to the second number


Randomly choose between 2 options:

CHOOSE( RANDBETWEEN( 1, 2 ), "Option A", "Option B" )


Randomly select a user:

CHOOSE( RANDBETWEEN( 1, 4 ), "u12345", "u0876234", "u567891", "u0987121" )


REMOVESPACES


You can remove spaces from the field in a placeholder with the function:  REMOVESPACES()


SUBSTITUTE


You can use this function to remove spaces of other characters or to replace some characters


E.g. SUBSTITUTE (client.vatnumber, " ", "")


DATEFORMAT


This function can be used to format dates to display in a specific way.


E.g. Payment is due {DATEFORMAT( job.paymentdate, "DD/MM/YYYY")}


This function replaces the existing date formatting option for placeholders, as DATEFORMAT can be combined with other functions.


E.g. {DEFAULT(DATEFORMAT(job.vatpaymentdate,"DD/MM/YYYY"),"n/a")}


The date formatting needs to be in quotes when used with the DATEFORMAT function.


Additional function options:


Calculate days remaining until a date


You can use this function to calculate days remaining until a certain date, or a number of days between 2 dates:  


{DATEDIF(client.date1,client.date2)}

{DATEDIF(today(),client.date1)}

{DATEDIF(client.date1,job.pivotaldate)}


You can use this within an IF function, to check for whether either of the date sources exists or not:


IF(AND(client.date1,client.date2),DATEDIF(client.date1,client.date2)) 


Support for logical functions AND() and OR() and NOT()


This function allows you to add extra conditions to an IF function, for example:


IF( AND(client.fees > 1000, client.grade = "A"), "Yay", "Boo")


Test for secondary contacts in placeholders


You can now test for whether a secondary contact exists before pulling their information into a placeholder, using the IF function:


{IF (client.contact2, "Contact 2 exists", "Contact 2 does not exist")}


Also:


Dear {client.contact1.firstname} {IF(client.contact2)} and {client.contact2.firstname} {ENDIF} {IF(client.contact3)} and {client.contact3.firstname}{ENDIF}


Computed fields


Form fields can now be computed from an expression e.g. the field "Annual fees" could be automatically calculated via:


IF(client.paymentmethod = "Monthly", client.fees*12, client.fees )



Service scope in placeholders


A new scope for clients to use in placeholders to do things if services are selected. 


For example:


{IF (services.s12345678, "You are on our Tax Return service", "You are currently not on our Tax Return service")}


You can find the service name by looking in the url for the service template.
