Error for not mandatory field

there is no highlight or any further information about adding the
data in the given segment, then the constraint or warning error does not
correlate to what it states! please find the attachment and en-light some views on it.

So might be development issue or may be some files need to be passed as false.

All the reports should be listed in Report field. I have no issue on my local account, check screenshot.

Hi Nabin, My area of concern was - As you have kept warning but there is no highlight or any red color marking to signify that we have to enter the data there that is why I emphasise on particular by marking in that fashion to understand. Hope now you are getting what i want to say. Precisely, I am highlighting on validation error which is not mentioned as we are having in Odoo.
