|Tool Name||PowerDesigner LDM (Logical Data Modeling)|
|Tool Version||15.x to 16.x|
|Tool Web Site||https://www.sap.com/products/powerdesigner-data-modeling-tools.html|
|Supported Methodology||[Data Modeling] Data Store (Physical Data Model, Stored Procedure Expression Parsing), Graphical Layout via LDM XML File|
Tool: SAP / PowerDesigner LDM (Logical Data Modeling) version 15.x to 16.x via LDM XML File
Metadata: [Data Modeling] Data Store (Physical Data Model, Stored Procedure Expression Parsing), Graphical Layout
Component: SybasePowerDesignerLdm15 version 11.0.0
This bridge imports data models from a PowerDesigner .LDM (logical data model) file with Entities, Attributes, Domains. This bridge also imports all relationships and their implementation (e.g. PK/FK) as well as the graphical layout (diagrams).
FREQUENTLY ASKED QUESTIONS
Q: How do I handle LDM XML files which contain shortcuts to external entities?
A: LDM XML model files may contain relationships which refer to entities defined as shortcuts, which are references to external entities. Unfortunately, in this case the LDM XML file does not contain sufficient information to reconstruct the PK/FK relationships properly. If this is the case with the imported file, there will be a message in the log like:
This model may have shortcut dependencies on external model: 'file:///...' and, by default, this bridge will not attempt to reconstruct those PK/FK relationships to shortcuts.
However, the source tool has the capability to merge these files together so that the shortcuts are resolved. To do so:
- Refer to the log for all the files with shortcuts
- Open the tool and go to the Tools > Merge Models
- Create a new merged model
- Save the new model as a LDM XML and import
Q: I see warnings or errors in the log, How can I validate the model before importing?
A: PowerDesigner allows checking of the model for modeling inconsistencies.
Please use menu Tools > Check Model and take necessary corrective actions to resolve detected issues.

LDM files in binary format are not supported.
Provide a trouble shooting package with debug log. Debug log can be set in the UI or in conf/conf.properties with MIR_LOG_LEVEL=6
|File||Imports LDM XML files. If you do not have the model saved as a LDM XML file already:
1. Logical Data Model is opened in Sybase PowerDesigner.
2. Choose 'Save As' from the 'File' menu.
3. In the 'Save as type' list, select 'Logical Data Model (XML) (*.LDM)'.
4. Enter the file name and select a directory to save the file in.
5. Click 'Save'.
This bridge will use the generated LDM XML file as input.
|Apply binary characters filter||Specifies if invalid binary characters should be filtered out of the file as a pre-process before parsing the LDM XML file. This option is a workaround for a bug in the PowerDesigner tool which sometimes generates a file that does not conform with the XML specification (contains binary characters).
Warning: Applying this filter may remove some unicode national characters.
|Import UDPs||A User Defined Property (UDP) is usually defined with a property definition object that has a default value. The objects that the property applies to may have an explicit value for this property. They may instead have no value assigned at all in which case the default value of the property definition (implicit value) applies.
Control how property definitions and values are imported:
Import the explicit value as the property value. Implicit values are not imported. The default value is kept on the property type only.
'As metadata, migrate default values'
Import the explicit or implicit values as property value.
'In description, migrate default values'
Append the property name and value, even if implicit, to the object's description property. This allows you to export the UDP values to another tool which does not support the notion of UDP.
'Both, migrate default values'
Import the UDP value, even if implicit, both as metadata and in the object's description.
|Append volumetric information to the description field||Import and append the volumetric (number of occurrences) information to the description property.||BOOLEAN||False|
|Remove text formatting||PowerDesigner stores annotations as plain text or Rich Text Formatting (RTF). Remove Rich Text Formatting (RTF) from annotations:
Target tool is capable of displaying RTF text.
Target tool is not capable of displaying RTF text.
|Reverse role names||Swap relationship rolenames for each model:
Do not swap rolenames.
