Informatica restricts which elements you can modify in the XML file. When you export a Designer object, the PowerCenter Client might include a Cyclic Redundancy Checking Value (CRCVALUE) code in one or more elements in the XML file. The CRCVALUE code is another attribute in an element.
When the PowerCenter Client includes a CRCVALUE code in the exported XML file, you can modify some attributes and elements before importing the object into a repository. For example, VSAM source objects always contain a CRCVALUE code, so you can only modify some attributes in a VSAM source object. If you modify certain attributes in an element that contains a CRCVALUE code, you cannot import the object.
For example, if you modify the OWNERNAME attribute in the source object, you cannot import the source into the Designer.
The following XML shows part of the element for a source object with the CRCVALUE code:
