It is not possible to do massive leaves request for a group of employees, by employee tag.
This is because, the leave request mode is only available "by employee". There is not drop down box, to change it into "by employee tag" mode.
I did trial in Odoo Online Demo account.
- Tag selected targeted employees, for ex : 10 employees with the word " Employee"
- Leave request allocation for 28 days Public Holidays , allocation mode "Employee Tag", tag name "Employee"
- All 10 employees, got 28 days Public Holidays allocation perfectly, but
- the record shown that allocation mode is converted into " by employee" for each individual, not "by employee tag" like what it supposed to be
My guess, this is the reason, why the massive leaves request does not work, by employee tag. Because the allocation mode, is got converted from "by Employee Tag" to "by Employee".
Which means, the tag is helping only to inject the holidays allocation quota in the beginning.
If anyone knows, how to request holidays/leaves based on tag, please jump in.
