SAP Note 22416 - No planned credit drng activ.input plan.in WBS elem.

Symptom:

Activity input planning on a WBS element (CJ40/KPR2) is not displayed as a reduction in cost center accounting, neither on a value basis nor on a quantity basis.

Cause and prerequisites

Since the planned credits on the cost center are used for the activity price calculation in CO-CCA, it is not possible to post a matching planned credit on the supplying cost center for activity input in a WBS element.
In addition, there are problems when updating planned data in profit center accounting (CO-PCA).
In SAP terms, there is no CO planning integration between PS and CO-CCA.

Solution
As of Release 3.0C, it is possible to activate the CO planning integration with cost center accounting on WBS elements.
An advance correction is not possible.
