When I am trying to import a document(.docx) in integrity 11.2 , I am having a problem like this. I didn't understand. Why it's happening.
Looking at the error message showing the type name with the "ALM_" prefix, my guess is that your system is configured without the prefix (so your type is "Requirement Document") and you're doing an import with a default gateway mapping that specifies the prefix.
If that's the case, you have to edit/create your own mapping and remove "ALM_".
On the server, the mappings are under "...\data\gateway\mappings", on the client, under "...\config\gateway\mappings", where "..." indicates the server or client root directory.
Then, one directory above, there's the file "gateway-tool-configuration.xml" that puts them together with the parsers.
I know, a major headache! I hope you have someone to help you.
LLawton is likely right, in that one of the type mappings may be pointing to an incorrect, or out-dated type name, not matching what is currently configured as the type name, on your Integrity server.
I'd suggest opening a Support case, with PTC Integrity (Windchill RV&S) support.
