Hi!
I dont know the meaning of all columns:
FAPP - Final APPraisal
FWGT - WeiGhT for FAPP
PAPP - Part APPraisal - when we want to have many part appraisal of one subject (object).
PWGT - WeiGhT for PAPP
OBJ* - Objective settings
2. Maybe for OBJ are additional business checks. For FAPP, PAPP and custom columns I use variety of BADIs.
My experience:
1.only FAPP - for simple appraisal. one element = one evaluation.
2. PAPP - 360-degree feedback - many evaluations (up to 18).
3. PAPP + FAPP - 360-degree feedback and calculated mean values in FAPP
4. OBJ* - objective settings applications (plans, facts, periods)
5. Z columns for own applications.
