The document provides instructions for planning activity output on a sender cost center in SAP. It describes allocating indirect employee costs to research projects based on productive and non-productive hours. Users must first create the necessary cost center and activity type master data. They can then use transaction code KP26 to plan the total annual hours for productive and non-productive activities on the sender cost center for a given fiscal year. The planned activity is split evenly across periods but can be adjusted if needed before saving.
