Address Distribution List Template

The Address Distribution List Template can be used in partnership with the Messaging and Scheduled Task utility to send emails to a table driven list of email recipients. This template has the additional option to map email addresses to an email group.

Applications created with this template are not expected to be run in the browser.

Template Notes

Application Settings

Description: Allow developers to specify their application’s description/name.

 

Program Name: This will be the application’s number. By default, m-Power uses the letter I (Inquiry) followed by a five digit number.

Select Only Matching Records: Select either ‘No’, for a left outer join, or ‘Yes’ for an inner join. A left outer join will return all records from the primary table along with matching records from the secondary tables. An inner join will return records from the primary and secondary tables only where matching records are found.

Template: You can select a template by scrolling through the available templates. The templates define the general layout and functionality of the resulting application. This section will list all the available maintenance templates; you will see a small screenshot of what that template looks like at runtime. Learn more about templates.

Data Selection

Here you will see/modify the table you have selected for your application, as well as create or modify joins to other tables as well.

Sequencing

Here you can select the field that your application will sequence by; you can have multiple sequence fields. You can re-order the sequences to fit your application’s needs. For practical purposes, it does not matter what you sequence by in this application, as long as you lick at least on sequence key.

Field Settings

Here you will find the settings for all the fields in the application. The options are:

Delete: You can delete fields by clicking the checkbox and clicking Accept. If a field has a red circle with a cross line, that means that the field is being used somewhere else in the application (sequence, calculation, etc.), and, due to this dependency, is not available for deletion.
Note: Deleting a field will remove the field from the application only, the table will be unchanged.

 

Field Name: This is the same name the field has in the table.

Table: The name of the table where that field exists.

Field Description: This is the text that will appear in the column header for that field, you can modify this field to suit your needs. This field will populate with the field description from the table by default, but it can be customized at the application level.

Display: A radio button allows developers to display or hide the field from the output page. There may be situations where a field is needed for calculation purposes, but the field does not need to be displayed at runtime.

Length: Here you can modify the length of the field. m-Power will only allow developers to shorten the length of the field, shortening a fields length will truncate its data. For example, if a field is 10 alpha and it is changed to 5 alpha, now only the first 5 characters will be displayed. The same principle applies to a numeric field, if a numeric field is 8 digits long; changing it to 4 digits long will only display the first 4 digits, and leave out the rest of digits.

Decimals: For numeric fields, you can modify the amount of decimal digits. A numeric field will have the option of changing its decimal length, alpha fields does not have a decimal option, developers can use this as an indicator to check if a field is a numeric or character type.

Numeric Format Code: For numeric fields, you can modify the way the numbers will display, this includes displaying decimals or not, how to display negative numbers, etc. Multiple formats are built in for developers to use, shall you need a different format code, m-Power allows developers to create their own User Defined Format codes; these codes will add logic for common types of fields such as: Currency, Time, or Dates. Accessing the User Defined Format Codes from the Admin section will also allow developers to modify current codes. Learn more.

Note: Do not confuse the User Defined Format Code with the User Defined Functions (UDF). The latter is a feature that allows developers to create or incorporate programing functions into m-Power. Learn more about UDFs.

User def: This feature has been deprecated.

Record Selections

Record Selections can be created over any database fields. These are the options:

Field: A drop down allows you to select the field you want to filter on.

 

Relation: A drop down allows you to select a relationship for the filter.

Value: This is the value to compare against. The options are:

Constant Value: A constant value allows you to hard-code any given value into a selection. This value cannot be modified by the end-user at run–time.

Application Field Value: Developers have the option of comparing a value from one field to a value from another field within the same record.

And/Or: When creating multiple record selections, you have the option to set them as “and” or “or” Example: selection A “and” selection B will display only records that match both selections. Selection A “or” selection B will display records that match one or both selections. Learn more.

Calculations

Calculations are a very powerful feature of m-Power; with calculations, developers can create logical fields that will apply to the current application only. For example, in the Address Distribution List template, you may want to create a conditional calculation to create your email group field.

External Objects

This feature allows developers to connect m-Power application with their current business logic, or to extend m-Power capabilities by allowing developers to write their own Java, RPG, or SQL programs, and integrating these programs into the applications. m-Power utilizes “locations” to connect the external objects, these locations vary depending on what the external object does and when it should be executed. The following locations are supported in this template:

*CALCOBJ This location is used when parameter calculations are present in the application. The external object is called after each row is processed.
*READRECRD This location will call the external object after each record is processed.
*STRADVSCH This location has been deprecated.
*ADVRECSEC This location has been deprecated. Learn more about Row Level security.
*SELECTFLT This location has been deprecated.
