Purpose of the flows is to guide users through screens for collecting and updating data – in my case I used them to guide volunteers to enter and schedule trips for volunteers
Elements are the building blocks of flows Each element represents an action Actions are connected into flows and then
variables, formulas are used to manipulate the data throughout and if you really want to manipulate the data you can plug-in an Apex class
Visual Workflow has 3 aspects:◦ Flow design◦ Flow Management◦ Flow Run time

Loading data from the Donation system requires multiple steps. To reduce the manual steps an intermediate temporary object was created and a trigger was attached to the object.
The reason was that the Account ID is needed to load the opportunity for the NPSP implementation. The trigger cannot be attached to the opportunity object because there are 6 triggers associated with that object and we don’t have the code for the 5 managed packages. In addition I really did not want to change these managed packages.
This left me with the solution of creating an intermediate object for the data being loaded in opportunity (donation) where I could hold the data until I populated it with the Account ID from the recently loaded Contacts.
The downside is that this intermediate object would have data in it that would not be monitored or cleaned up since I could not delete it with the trigger I just added on the intermediate object since the commit was not complete.
The solution was a single wizard once the loading was complete the person doing the loading would select a single button that would do the final cleanup.

First you will identify if you will be looking up a Standard or
Custom Object
Then identify Standard or Custom field in the Object
Then select the operator
Then enter the value you can create a new value or as in this
case use a system valueIf you want to add additional filters then add a row.
Record Look up

point.

Make a DecisionThe decision logic from the
Palette acts much like an If then else conditional statement.
Provide a name and it will appear when you make the connection
What is your conditional statement? You can add multiple conditions and either “and” them
or “or” them
The Default Outcome would be the else outcome

16
Create a loopPlacing this decision and the
lookup created a loop in the logic the loop is a “do while” there is still a record to look up in the
object delete it
The names from the decision of the statements
The else condition

Display Content to the Screen This is the component that you will
use to interact with your user, to request input and to provide
information. In this case I displayed the output that the wizard was
complete. The field output can be formatted using HTML markup.

have to be defined appropriately

Not everything can be done through Cloud flow and sometimes you need an APEX class.
You can develop an APEX class and an APEX test class and integrate it into your cloud flow for even more flexibility.
From Setup, click Create | Workflow & Approvals | Flows and open a new or existing flow.
From the Palette, drag an Apex Plug-in element onto the canvas. The class name and plug-in description are taken from the plug-in code.
Enter a name for your new plug-in element. If you haven’t already added a description, click Add
Description to do so. On the Inputs tab, assign values to the Apex parameters.
Required parameters are automatically listed as targets.
