Event R401 not executing

Question

Dear Experts,
During billing i am posting some debits and credits at the same time to customer account. I want them to be cleared when i invoice them. i read posts of other people who have similar problems but after debugging i realised that system is not executing event r401 at all for some reasons.
i have made the config where we need to define clearing type and clearing category and check the acct maint indicator. table te514 and te529 also configured
Also please tell if there is any way of knowing which clearing variant is being executed at acct maint(if any)
Any help would be highly appreciated
Thanks!

Answer 1

Dear Experts,
I have been debugging ISU_INV_ACC_MAINTENANCE but I still havenu2019t achieved what I wanted to do so I tried a few different scenarios. Please let me know if it is supposed to work the way I want it to. Please assume that the necessary configs have been done
Scenario 1
-     I billed a consumer using periodic billing. The schema was such that two debit items were posted of say Rs 100 and a credit item was posted for say Rs 100. So in effect the receivables are 100.
-     I ran invoicing
-     Using fpl9 when I see consumer balance it shows three line items. Two for the debit receivable and one for the credit. 
-     Desired result was that during invoicing, the system would run something like automatic clearing and would clear one of the debit with the credit(as per clearing rules). However this did NOT happen
Scenario 2
-     I posted a downpayment request for some consumer of Rs 100(Downpayment has clearing restriction 8)
-     Customer paid Rs 100.
-     I billed the consumer using periodic billing. The schema was such that two debit items were posted of say Rs 100 and a credit item was posted for say Rs 100. So in effect the receivables are 0 because we already have received a downpayment of 100.
-     Desired result was that the credit posted during billing would clear with one of the debits of the bill and the downpayment would clear against the other debit posted during billing(as per clearing rules). However, no clearing took place and all documents are intact
These are the comfigs I have made
i)     Acct maint has been set to active against the clearing type in u2018additional controls for invu2019
ii)     Table TE514 maintained with mains and subs and clearing categ and clearing type
iii)     Clearing variant assigned to R41 and R4 in FI-CA
iv)     Invoicing document shows clearing type R41 in ea40
Please suggest if this isnu2019t the way the system is supposed to behave
Would really appreciate. Feel free to ask if any confusions
