Use descriptive naming. Name will show to the user when an error occurs, and helps to faster troubleshoot any issues.
It is very important that all flow developers adhere to naming convention explained below. This standardization helps to easily identify what type of a variable you are using.
DO: Follow this naming standard when naming variables.
- Variable names should be in Pascal Case. (e.g. CustomerOrderTbl)
- Variable names should be readable and meaningful.
- Name datasets/tables with suffix "Tbl".
- Name records with suffix "Rec".
- Name fragment output target variable in a flow with prefix "Out" and suffix "Rec".
- Table column names should be in Camel Case.
DO NOT: Things to avoid when defining variables:
- Do not use variable names such as "var1", "CusoTbl" which are not readable and descriptive.
- Do not end the variable name with underscore (PL/SQL style), this will not work for records in Flow which are used in backend Oracle code. This will be fixed in newer releases but avoid anyway, for readability.
- Avoid using variables with the same ID in WHERE conditions. For example: lets say you have a table called "PartNoTbl" with columns "PartNo" and "Description". And you have a user input variable which is also "PartNo". When you want to get the description of the part no entered by the user you need to write a statement as follows.
In this case, flow will return the description of the first part no on the table instead of Part No you selected.Thus, how the PartNoTbl columns should have being defined is "Id" and "Description" which will work fine in the following statement.
- First(PartNoTbl where PartNo = PartNo).Description
- First(PartNoTbl where Id = PartNo).Description
Always align menu names with the menu Title. Keep all menus under one folder in the Flow Studio folder structure. Think through the content in each menu together with the role setup.
