JCo Error in Mii 12.1.4

[Former Member]

I am having problems with JCo in Mii 12.1.4. When the JCo Function builds the Output XML structure properly but does not build the Input Structure at all. When I look at the Log Viewer I see this error:

JCO Proxy Error: INVALID_CHARACTER_ERR: An invalid or illegal XML character is specified.

[EXCEPTION]

org.w3c.dom.DOMException: INVALID_CHARACTER_ERR: An invalid or illegal XML character is specified.

If I try to use JRA the Input and Output structures are generated correctly. In this case the same message is inserted into the log but only as a warning.

What is going on here? Can someone please help?

Thanks

There is a very good chance this issue has been corrected in a newer service pack. Have you been through any of the release notes on service marketplace? 12.1.8 is the latest update, and also requires NW SP5.

I have also tried this in our Mii sandbox (version 12.1.8 Build 28) with no luck.

What BAPI are you using? Is it the same for all BAPI's?

If the latest build is still showing an issue on your sandbox, then perhaps logging a support ticket is a good next step.

Jeremy,

We are calling a custom BAPI. I had the ABAP developer change one of the inputs in ABAP function module from a table to a flat structure and it is now working. Very strange, indeed.

The input table contained only one field with a length of 2 characters.

Thanks
