Code for virtual characteristic

Before coming to ABAP code portion we first need to know what basically the virtualcharacteristics or key figures are.Virtual characteristics and key figures appear to the user like their normal counterparts,

yet they are calculated in standard BW user exits, where you can program your ownlogic. his complex logic, which must be created in ABAP, is executed at the same timeas the !uery. Although the virtual characteristics and key figures are not actually

populated in the database, we can not see data through infoprovider, though they areincorporated into an "nfo#ube data model so the ob$ects can be selected when designing a!uery. %ike other normal characteristics, virtual characteristics must also be incorporatedinto the appropriate dimension.

he following example describes how to implement virtual characteristics, and these principles also apply for setting up virtual key figures.

"n our pro$ect scenario we have one characteristic &#'()* A , which does not physically store any value, but it should be populated by + - during !uery runtimedepending on two date fields. And ultimately one key figure will be restricted by thisvirtual characteristic with value + -.



*o for this we have to write ABAP code in the enhancement component RSR00001 which contain the function module EXIT_SAPMRSRU_001 for virtual key figures andcharacteristics.

he ABAP program has three parts

"n the "nclude & /*/012 we have to make the virtual field setting. his includeis re!uired for the selection of characteristics which needs to be read or written.

#haracteristics have to be stored in table E_T_CHANM where as 3ey figureshave to be stored in table E_T_ !"NM
