Custom Properties #
The Custom Properties define the properties unique to the component. When parameterizing the component using SSIS variables, the Custom Porperties are overwritten.
List of relevant Custom Properties:
| Property | Comment |
|---|---|
| ColumnNameStyle | Code: the SAP technical column name is used as column name in the destination e.g., MAKTX. PrefixedCode: the SAP technical column name is prefixed by SAP object name and the tilde character e.g., MAKT~MAKTX. CodeAndText: the SAP technical column name and the SAP description separated by an underscore are used as column name in the destination e.g., MAKTX_Material Description (Short Text). TextAndCode: the SAP description and the SAP technical column name description separated by an underscore are used as column name in the destination e.g., Material Description (Short Text)_MAKTX. |
| ConvertsDates | When this property is set to True (default) SAP date fields (YYYYMMDD) assume the SSIS pipeline type DT_DBDATE instead of DT_WSTR. In case of invalid data in SAP date fields, the following date conversions are applied: InvalidDateReplacement, MaxDateReplacement, MinDateReplacement. |
| InvalidDateReplacement | Allows the replacement of an invalid date format. The default value of the property is 1970-01-02. To use the property enter a replacement value for invalid SAP dates, such as ‘20190132’ (January 32nd 2019) in the format yyyy-mm-dd. The value NULL is supported. |
| MaxDateReplacement | Allows replacing the SAP dates with the year 9999. The default value of the property is 2099-12-31. To use the property enter a replacement value in the format yyyy-mm-dd that contains the year ‘9999’. Example: ‘99990101’ (January 1st 9999). The value NULL is supported. |
| MinDateReplacement | Allows replacing the SAP dates with the year 0000. The default value of the property is 1970-01-01. To use the property enter a replacement value in the format yyyy-mm-dd that contains the year ‘0000’. Example: ‘00000000’. The value NULL is supported. |
Parameterizing Using Expression Properties #
The recommended way of parameterization is to use SSIS expressions to set Data Flow Properties.
Data Flow Properties are displayed in the “Properties” window of the Data Flow Task.
These properties are not to be confused with Custom Properties that are displayed in the “Properties” window of the component.
When parameterizing the Data Flow Properties, the Custom Porperties are overwritten.
For more information on property expessions, see Microsoft Documentation: Use Property Expressions in Packages.
How to Use Expressions for Data Flow Properties
- Create an SSIS package, see Getting Started.
- Right-click the Data Flow canvas and select Properties. The window “Properties” opens.
- Add an Expression by clicking using […]. The window “Property Expression Editor” opens.
- Select a property from the drop-down list under Property.
- Open the “Expression Builder” using the […] button under Expression.
- Build your Expression and click [Evaluate Expression] to check for correct syntax.
- Confirm your input with [OK].
