Error description
A CICS transaction performs a LINK from one region to another passing a channel. The task subsequently makes an INVOKE SERVICE call but this fails as the remote service rejects the SOAP payload as containing unexpected non-XML data. The reason for this failure is that when the DFHREQUEST container is created for the INVOKE SERVICE the code page of the imported channel (the LOCALCCSID of the original region) is incorrectly used despite the data in the container being in UTF-8. This causes a LOCALCCSID to UTF-8 conversion to be performed by CICS on the SOAP payload that is already in UTF-8. This corruption of the payload causes the remote service to reject the request.

Problem summary
**************************************************************** * USERS AFFECTED: All CICS users. * **************************************************************** * PROBLEM DESCRIPTION: A program is linked via IPIC with a * * channel and the transaction fails with * * an XML parsing error and an AEIP * * abend. * **************************************************************** Two CICS regions are connected via an IPIC connection. A transaction in region SYSA issues an EXEC CICS LINK with a CHANNEL to a program in region SYSB. This runs a CSMI transaction on SYSB and the program makes an INVOKE SERVICE call. A DFHREQUEST container with CCSID 1208 is reserved to hold the constructed SOAP message. The source XML data is already UTF-8 encoded with CCSID 1208 but it is incorrectly treated as the LOCALCCSID from SYSA. Instead of simply copying the data, it is also translated from EBCDIC to UTF-8 which makes the data unreadable. This leads to an AEIP abend.
Problem conclusion
DFHPGCR is changed to always use the caller's CCSID value when the function is RESERVE_CONTAINER.
