Hello Aditiya,
at first glance, it sounds like the situation is as described in the long text of note 1171921:
By default, there is no interest calculation method for dividends specified. In this
case, the system takes the method 360E/360 as default and no flow is
generated for either the 30th or 31st of a month.
So I would suggest to proceed as the note explains:
1. set the interest calculation method to optional in the field
selection,
2. change to some other interest method in the detail
screen of the dividend condition items in FWZZ (e.g. act/360).
3. FWUP. The missing dividend will show up.
Best regards,
Marie
