Workflow - how to set working only for a specific month
I would like to set the operation of specific workflow only for a month specified.
I have a field name "field_a" in [ACCOUNT] that I wants to be updat with different calculations depending on the month.
The update is to be active for the entire given month.
I set 12 workflow, and I do not know how to set them to working only in a particular month.
I can specify the month by Date field in [ACCOUNT].
Please help,
Regards,
Piotr.
