Deferred revenue in FICA for Posting from SD to FICA

Hello,

We have requirement to post deferred revenue and run the posting on monthly basis. Below are the flow of document posting.

1. Posting from FICA - FPE1 - System is able to defer the revenue and deferal can be run through FPDR

2. Posting from SD - to FICA - System is not generating deferred posting for the said document

3. Posting from ISU-Billing to FICA - System is not generating deferred posting for the said document

For all the three scenarios above we need to run deferred revenue through FPDR on monthly basis

Please suggest.

Regards,

Narendra
