I was trying to update VSAM file through CICS map. I was able read the VSAM file through the CICS map without any issues. I was getting AEIP abend. But now I am constantly getting abend AEIM, and am not able to figure it out. One of my friend asked me to check if MDT is on or not. I have checked that also and even then I am not able to shoot down this ABEND. I also checked if I was doing anything wrong while defining the file in CEDA DEF F. Any type of suggestions are invited.
