How To Fix U1607 - Form number required for selected action.

U1607 - Overview

• Message type: E = Error

• Message class: U1 - Tax reporter interface

• Message number: 607

• Message text: Form number required for selected action.

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

The Form Number is a number that uniquely identifies a particular Tax
Reporter execution for a given <ZH><ZU>Tax Form</></> / <ZH>
<ZU>Reporting Period End Date</></> combination.
The Form Number represents the first 6 characters of the key of the Tax
Reporter cluster (cluster PCL4 id U1).
The Form Numbers are generated in Tax Reporter as follows:
<ZH>Production Mode</>
A different Form Number is generated for each <ZH><ZU>Tax Form</></> /
<ZH> <ZU>Reporting Period End Date</></> combination. The Form Number
is not Tax Company dependent. This means that if you execute Tax
Reporter in production mode for a given Tax Form and Reporting Period
End Date for two different tax companies, Tax Reporter will use the
same Form Number for both companies. The range for Form Numbers
generated in production mode is 000001-899999.
<ZH>Test Mode</>
A different Form Number is generated every time you execute Tax
Reporter in Test mode. The Form Numbers for test mode executeions are
always greater or equal to 900000.
To find out what Form Number you should use, in both producion or test
mode, look at the Tax Reporter Log Manager, selecting the Tax Company,
and Tax Form class that you are interested in. The Log Manager will
list all the Tax Reporter executions for that particular Tax Form
class.
Open up, the Tax Reporter execution that you are interested in, and
search form Form Number.
For production executions, you can also find the form number under
transaction SE16, table V_5UXY_A, but you need to know the technical
name of the form you are interested in (i.e. HR_F_W2, HR_F_941,
HR_F_UNEMP*). To restrict the number of entries in SE16, enter as much
information as you can in the selection screen (End date, Form Type =
'M', Tax Company, and so on).
