Unable to upload profile values via excel-import

Dear colleagues,

I have created a 15mins interval profile, assigned it to a register, and changed values manually.

Also I was able to upload some values using the two Bapis (upload and import).

Then I continued, tested the export via excel, changed the values and the status and tried to upload it but it failed, telling the following error message:

"Error 4 on Import with time 1.04166666666667E-02; check the import file".

I was checking the import file (picture attached here) but did not find anything that looked like an error to me.

For some help solving this issue I am very thankful.

Kind regards,

Manuel
