Table maintenance generator on Maintenance View giving data update issue

Hello Experts,

I have created a maintenance view on a custom table and rearranged the fields in the maintenance view as per my requirement.

After that I have created a table maintenance generator (TMG) on the view. The issue is, when I enter values to the view using

SM30, no values are getting saved in the actual table, except the primary key. My custom table contains currency and date fields.

Can this issue be because I have rearraned the date and currency fields in the view? Sometimes the values are getting saved also,

which makes it very inconsistent.

Is there any other way of doing it (say by using events etc). Please advise.

Thanks.
