Dear Gergej
Just a wild guess:
After CK74N when you did the CK11N. did you save that.
Also check the Cost component in which this additive cost is to be added that it covers fixed and variable both in 'Cost share', because if you give price in CK74N in the Price-fixed column than it is treated as the fixed cost.
Hrusikesh Dalai you are very right that If BOSS is there then we can only give wild guesses. All concrete points he already mentions in his replies. But no harm in trying,
Right Ajay Sir?
