Collective Bill -Autoclearing error cross clear member accounts

[harikaku]

Auto clearing for collective cross clears across member account. We do not want to cross clear credit across member contract accounts. It is ok for the collective account to cross clear payments but credits needs to remain back to member account. User exit FKK_SAMPLE_TFKK115 does not provide the option to do that.

Scenario

Member Contract accounts have credit open items and some member accounts have debits overdue. After invoicing run, when auto clearing is run, the extra credit lying on member account is automatically transferred back to the group account and that in turn clears individual member accounts that have an outstanding balance which is an issue. We have used the standard SAP variant 20S to run auto clearing. For payments it is OK to cross clear but credits are not allowed to cross clear member accounts

We have investigated the use of alternative clearing variant exit FKK_SAMPLE_TFKK115 by modifying the content of table T_FKKCL_E115 as shown in the screenshot below. The credit amount in T_FKKCL_E115 is available as total credit amount at a collective bill document level rather than individual member credits, thus not allowing to write rules to not cross clear and just clear within the member accounts. This is an issue as the exit needs to be extended to allow us to see individual credit line items so that we can prevent cross clearing member account. Example account is pasted below with screen
