Introduction:

This document describes what can be the cause if a XCOM-transfer from the Mainframe fails with message
XCOMM0243E INVALID OR INCOMPLETE DCB CHARACTERISTICS

Instructions:

When you receive message: XCOMM0243E INVALID OR INCOMPLETE DCB CHARACTERISTICS

please check the DCB-Characteristics of the file which is being sent. For example, if a file has these characteristics,

Dsorg Recfm Lrecl Blksz   
--------------------------   
PS    VB    0     27998

XCOM can not transfer it because these are not parameters which are supported by IBM. LRECL=0 is valid only for RECFM=U as stated in the IBM Manual "z/OS V1R12.0 MVS JCL Reference (SA22-7597-14)" although there might be tools or programs which are able to allocate such files.
XCOM supports all files which are allocated by using ISPF-Option 3.2 or by any JCL following the guidelines of the JCL Reference.
