Let us consider calculating profit as example

Profit := Income-Expenditure;

There is no guarantee that Income and Expenditure data will always have a numeric data type. Some users may prefer to use ‘No Income’ or ‘No Expenditure’ values

Script Dynamic Action

Wed, 17 Sep 2025 00:00:00 +0000

About

Script package action enables the implementation of advanced checks and validations.

Two languages are supported:

Pascal Script
Python

Pascal Script Example

Var I : Integer;
begin
 I:=1;
 SetVariable('I',I);
 I:=GetVariable('I');
 WriteToLog('Error',I);
 Result:=True;
end;

Result:=True; => Success
Result:=False; => Failure

Python Example

import etltools
etltools.SetVariable('<Time>',15)
s=etltools.GetVariable('<Name>')
etltools.WriteToLog('Done')
Result.Value = 0

Result.Value = 1 => Success
Result.Value = 0 => Failure

About

Script package action allows writing additional complicated checks and validations.

Two languages are supported:

Pascal Script
Python

Pascal Script Example

 I:=GetVariable('I');
 WriteToLog('Error',I);
 Result:=True;
end;

Result:=True; => Success
Result:=False; => Failure

Python Example

import etltools
etltools.SetVariable('<Time>',15)
s=etltools.GetVariable('<Name>')
etltools.WriteToLog('Done')
Result.Value = 0

Result.Value = 1 => Success
Result.Value = 0 => Failure
