SAP Flexible Benefits Enhancement - User entry details change

Hi,

We are currently implementing SAP Flexible Benefits for one of our clients (they are on EhP6).

We have a requirement as follows:

When the user selects the ‘Gym Membership’ benefit from the Miscellaneous Plans tab, we require them to be able to enter some additional information relating the gym, i.e. Gym code, membership code and membership cost.

The ‘Gym membership cost’ entered should then replace the ‘Pre-Tax Costs’ amount for this particular benefit.

The configuration which has been done is as follows:

Structure RPBEN_OE has been modified to include the 3 new fields shown on the screen shot above by appending a new structure.

Component configuration HRESS_CC_BENF_ENR_GAF has been copied to ‘Z’ version ZHRESS_CC_BENF_ENR_GAF.

Created a new UIBB in FPM_UIBB_FORM configuration by copying configuration HRESS_CC_BEN_MISC_PRETAX in dialog box SEL_MISCELLANEOUS_PLAN to a ‘Z’ version and added it to the configuration ZHRESS_CC_BENF_ENR_GAF:

I also copied the feeder class in the configuration to a ‘Z’ version, i.e. CL_HRESS_BEN_INSUR_ADD_COV to ZCL_HRESS_BEN_GYM_ADD_COV.

The configuration where the pre-tax value is currently being displayed is HRESS_CC_BEN_OVR_MISC_FORM_DET which uses feeder class CL_HRESS_BEN_PLAN_DET_FORM_OVR

And the configuration for the new ZHRESS_CC_BEN_GYMFLEX uses feeder class ZCL_HRESS_BEN_GYM_ADD_COV which is a copy of feeder class CL_HRESS_BEN_INSUR_ADD_COV.

So the 2 issues I need assistance with are:

1. How to replace the ‘Pre-Tax Cost’ amount shown by the ‘Gym
   Membership Cost’ entered by the user.
2. How to only display the ‘Gym’ related fields only for the ‘Gym
   Membership’ plan and not for any of the other ‘Miscellaneous Plans’.

Any assistance on the issue would be greatly appreciated.

Thanks, Raj
