Fundamentals of the PROCESSES branch


The DATA PROCESSING ACTIONS are the PROCESSES equivalent of similar ACTIONS on under an EVENT PROCESSING elsewhere on the Tree.

    • set an explicit SCALAR to control logic of another PROCESSES branch object
    • conditionally extract information from a file
    • generate timestamps during the submission process


A read or write to a database is done via a PROCESSES→DATABASE ACTION

DATABASE ACTION is a Parent to DATABASE, which in turn is a Parent to READ and WRITE

Excel Objects

As introduced in Interacting with an Excel spreadsheet, an EASAP can interact with Microsoft Excel spreadsheets within the USER INTERFACE branch via a Cell Reference in data entry objects or via an ACTION within an EVENT PROCESSING. In the PROCESSES branch, only the ACTION approach is available. In this case interaction happens on the EASA Server during a batch EASAP submission rather than the user’s client computer during an interactive user interface session.

Changes made to an Excel spreadsheet using interactions located in the USER INTERFACE branch will not be available to the ACTIONS located in the PROCESSES branch at the time of submission. The ACTION's in the PROCESSESS branch are always applied to the original uploaded version of the spreadsheet file. Therefore, the two approaches are NOT currently designed to be used in combination.

  • The process of making EASAP's interact with Excel spreadsheets in the PROCESSES branch involves two basic steps,
    1. Defining connections to the spreadsheets from the workbook files on down to the various worksheets
    2. Performing Excel specific actions using EXCEL ACTION's found on the PROCESSES branch

Order of Operation within the PROCESSES branch

  • the order of execution within a PROCESS object is always
    1. DATA PROCESSING objects
    2. REPLACEMENT objects
    3. commands specified in the Run Using: parameter of the PROCESS object
    4. the CLEAR FILESPACE object
  • the order of objects on the Tree within a PROCESS is not important.
  • the order of execution of multiple PROCESS objects is based on their order on the Tree
    • → execution order is from top to bottom, a PROCESS completes and then next is begun

Input data for the software applications being run in one PROCESS can be extracted from the output files of software applications run in a previous PROCESS using an EXTRACT.

Process View

At the bottom left of EASAP Builder are icons that allow you to toggle between Tree view and Process view.

The Process view provides a flow diagram of the objects within the processes branch and you can right click on images in the diagram to insert new objects. Parameter values of objects can be set in the lower left part of the window.

The diagram can be adjusted by dragging and clicking boxes. Please note however that their location is not saved when EASAP Builder is closed. The diagram can also be manipulated through its toolbar, which contains operations including zooming and a variety of automatic layouts.

The toolbar also allows the diagram to be annotated with any “do if” expressions The overview panel allows you to select a subset of the diagram for viewing by dragging around the shaded rectangle.
