Question:

Is there a possible reason I would get an error message "Error creating table" in Tran View?

 

Answer:

You will also find that when the cursor is over any field and "F1" is selected, the following message is displayed:

"Error creating table - User-defined warning criteria will not be available.
Error for TBCREATE rc=8 TBOPEN issued for table TUNKWRNT that is already open"

A possible solution to this error involves the ISPTABL DD allocation.

From the CA MAT 10.0 Install Guide

https://docops.ca.com/ca-mat/10/en/installing/customize-ca-mat/step-10-define-cics-support-and-customize-optional

After completing these steps for each CICS region that you will monitor, you must allocate ISPTABL DD to your ISPF logon PROC if it is not yet allocated.
Note: By completing this step, you have successfully finished the customization of CA Mainframe Application Tuner for a single CICS region.
However, all customization steps for CICS support must be repeated for each CICS region that you will monitor using CA Mainframe Application Tuner. 
<END> 

Please make sure that the ISPTABL DD is allocated.
