Hi Ruks
Not withstanding any bug in Simple Finance, this is what I feel.. If it does not help, raise an OSS message
1. You can always enter plan rates in KP26 manually.. Ensure that Plan Price indicator in Act Type Master is set to Manual Price (I think it is 3)
2. If you want to calculate actual price automatic based on activity qty, ensure that
a. Actual Price indicator in Act Type Master is set accordingly
b. Also, check the indicator in KBK6... Set it to "automatic based on activity qty"
3. Splitting Structure is what you say you have ensured. But please provide a screenshot (OKES and OKEW) for me to review..
4. Now do KSS2 and provide screenshot of the error if it is still there..
5. Also do KSII and see if there is any error / act price is fine
