Hi Rajkumar,
As you have multiple planning modules in APO e.g. DP, SNP, PPDS, TPVS. Therefore, to segregate the responsibility of different user (planners) to carry out functions in these modules, corresponding planner codes are defined.
These codes then help in selection criteria while running different t-codes or reports in view of the set of product/locations that planner is responsible for.
The production planner in APO is suggested to have the same code as MRP controller in R/3.
You define the planner codes in APO under IMG APO->Supply chain planning->specify person responsible (planner).
