PH52190: INVOKE SERVICE SENDS CORRUPTED PAYLOAD AFTER A DPL PASSING A CHANNEL

Obtain the fix for this APAR.

APAR status

• Closed as program error.

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.

  ****************************************************************
  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.
