UPDATED: March 13, 2019
Description: 
"This is due to a Carrier Route job with a large number of input records. The DTRECS table is being exceeded. Add this parameter: 
TABLSZ DTRECS nnnnnn 
For the n's, the default table size is 002000, you can try 004000. Depending upon the file being presorted, this may need to be increased. Maximum is 20000. (Note: Beginning with the MailStream Plus™ 8.3.0 release, the default will be 005000.)

(FYI- In the MSNA00x step, the table is referred to as TLBLKS, but you define a TABLSZ DTRECS to change the table's size.)"
