Problem updating billing plan Dates for rental contract

[former_member544521]

I am trying to update Billing plan dates for rental contract. I am using FM 'BILLING_SCHEDULE_READ' to read Billing Plan details. then using FM 'BILLING_SCHEDULE_SAVE' I am able to update FPLA and FPLT tables. but When I go to VA42 to check I see that Net Value for that Item under Billing Plan is not been updated according to current Dates. Could anyone Please provide me with a way to auto update Net Value once Billing Dates are changed.

Well, you called an update task FM which, as most of its kind, only execute some update of database without any check (except database constraints) or any database consistency task.

1. Don't call update FM in your code
2. Always perform much search (where-used) on those FM
3. (for expert) Never call update FM in your code

Hint: Did you look at the FM API_RE_* or BO BUS1505 provided by SAP (Ref. 782947 - Programming interfaces for RE-FX)
