What is a variable_pool and how is it used?

[Mira3]

Hello, 

what is a variable_pool and how is it used in workflow activities? 

Thanks for the help!

[Nitin_NOW · Accepted solution]

it is an object where you can access the field values of RITM and can be used in workflow activities (Advanced Script)

for example if there is a field on the RITM page - 'Please select size of Hard disk' and the value entered/selected is '250GB'.

If you wanted to access this field value in the workflow script, below is the way you get it via variable_pool

current.variable_pool.size_harddisk //size_harddisk is the variable name of 'Please select size of Hard disk'.

Please hit correct based on response.

Thanks

Hi Mira,

variable_pool is used to retrieve variable values in workflow activities; usage

current.variable_pool.<variableName>

you can also use

current.variables.<variableName>

you can use this in any server side script with condition that current is object of sc_req_item table.

Mark Correct if this solves your issue and also mark Helpful if you find my response worthy based on the impact.
Thanks
