Issue in table VBAP enhancement

Hello Experts,

I have enhanced three custom fields to table VBAP and gets activated, later on I have tried to add one more field to the same structure but received error message.TABL VBAP is inconsistent in active version

Later on I have tried to delete the custom structure from VBAP but the activity not completing I mean which is still deleting and taking more than 3 hours.

Now I wanted to delete the custom structure and to recreate structure with new fields. And table doesnt have entries for the custom fields.

Can you please help me to address this issue.
