HIER_28004 XML Reader Error: <error text>.

Explanation:
This is a generic error.
User Response:
Check the session log for related error messages.

HIER_28020 DTM buffer block is filled, and we can't send the block yet. Need to use heap memory to hold data.

Explanation:
In the XML file, leaf elements appear after multiple-occurring enclosure elements of a parent element. The memory block for the multiple-occurring enclosure elements is filled.
User Response:
Restructure the file so that all of the leaf elements of a parent element appear before the multiple-occurring enclosure elements.

HIER_28028 Fatal Error: Could not allocate memory from heap.

Explanation:
In the XML file, leaf elements appear after multiple-occurring enclosure elements of a parent element. The Integration Service has now run out of heap memory.
User Response:
Restructure the file so that all of the leaf elements of a parent element appear before the multiple-occurring enclosure elements.

HIER_28031 There are two fields pointing to the same XML node, but the datatypes and lengths do not match.

Explanation:
The Source Qualifier transformation contains different ports based on the same XML element. The datatypes or lengths for these ports are different.
User Response:
Check the Source Qualifier transformation and make sure the datatypes and lengths for all occurrences of the element match.

HIER_28032 Error: There are no fields in any of the groups defined that have a reference to a node in the XML tree.

Explanation:
The XML map for an element in the XML file is blank.
User Response:
Contact Informatica Global Customer Support.

HIER_28034 Could not retrieve a block from the DTM.

Explanation:
The reader thread could not retrieve a block of memory from the DTM buffer pool.
User Response:
Contact Informatica Global Customer Support.

HIER_28041 Couldn't open indirect file <file name>.

Explanation:
The session is configured to read from a file list. The Integration Service could not open the specified file list.
User Response:
Verify that the file exists in the specified directory. Also, grant read permission on the file and directory to the Informatica Services account or the operating system user in the operating system profile. Then, run the session.

HIER_28043 Reader failure: The node <element name> occurs multiple times. This node was marked in the schema as occurring one or less times.

Explanation:
You imported a source in the Designer based on an XML file. In the source qualifier, the Designer marked one of the elements as a single-occurring element. When you used this source in a mapping, the imported XML file contained the element multiple times.
User Response:
Recreate the XML Source Qualifier transformation using a more accurate XML file.

HIER_28044 Reader failure: The root node for the given XML does not match the root node in the repository.

Explanation:
You imported a source in the Designer based on an XML file. The Designer determined the root element based on this file and stored it in the repository. When you used this source in a mapping, the imported XML file contained a different root element.
User Response:
Check the XML file and then import it again.

HIER_28045 Out of range error: <element name>.

Explanation:
The element stored in the repository is a decimal number with a specific precision and range. The precision for the element in the XML file does not match the precision stored in the repository.
User Response:
Check the precision for the element, and then import the XML file again.

HIER_28051 Read invalid number <value> for XML path <path name>.

Explanation:
The Integration Service failed to read a value from an XML file because the datatype defined in the XML source definition does not match the datatype in the XML file.
User Response:
Verify that the datatype defined in the XML source definition matches the datatype in the XML file.
