Tally crashes when I open Group Company
Step 1: This error may occur when you're syncing Main group company in Tally as given in the image:
Step 2: So to avoid this error you need to select "Sub- Group Company" instead of Main Group Company in Tally i.e Group 1 or Group 2.
Step 3: After this Biz Analyst Sync will work fine and you will not get MAV error.
