How To Fix K6109 - Please don't make column unit from column '&1' input-ready

K6109 - Overview

• Message type: E = Error

• Message class: K6 - EC-EIS/EC-BP data basis: Data entry and collection

• Message number: 109

• Message text: Please don't make column unit from column '&1' input-ready

What causes this issue?

You have put the periods in the rows or columns of the layout..
simultaneously a quantity key-figure without a fixed unit was chosen in
the column '&V1&'.

System Response

If entries are only made for one period, you can ignore this message.
Otherwise no entries can be made for the unit of the quantity key
figure as no differing units can be included per period with otherwise
equal characteristic values.

How to fix this error?

There are other possibilities:
Put the periods in the general selections. An entry for the unit can
then be carried out during the data entry in the overview screen.
Set the unit column of the column '&V1&' to 'not ready for input' (Menu
path: Formatting -->Ready for input y/n).

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

Attention
In the last case you couldn't make any entries for the key-figure
without a fixed unit, as entries without a unit are not accepted.
