error T0042: Action '%s' - mandatory parameter %d is missing.

Cause

This error occurs when a mandatory parameter for the action is missing.

Solution

Give the mandatory parameters when necessary.

Example

[#Form: Balance Sheet]

Add: Button: MyButton

[Button: MyButton]

Action: Display

In the above example, the mandatory parameter is missing for the action Display. Hence the message error T0042: Action 'Display' - mandatory parameter 1 is missing.

The code is corrected by giving the report name.

[#Form: Balance Sheet]

Add: Button: MyButton

[Button: MyButton]

Action: Display: Day Book
