3421091 - Missing real time revenue recognition postings triggered for projects

There's no real time revenue recognition postings generated with the original postings to sales order.

SAP S/4HANA Cloud

The related accounts of original postings are not mapped to Event Based Revenue Recognition(EBRR) source or mapped to ***YM0 source.
APP "Event-Based Revenue Recognition - Sales Orders", choose "Revalue"->"Simulate"->"Explain Simulation".
Under "List of applied assignment rules", there are messages like:
Condition type XXXX: there is no assignment to a source.
G/L Account XXXX: there is no assignment to a source. 
or messages like G/L Account XXXX: source '***YM0 :Miscellaneous Expenses Not Relevant for Rev rec', usage '202 :Cost without Revenue Recognition Processing'.

In all assignment rules,the source ID “YM0” at the very end of the table. It is used for the costs without revenue recognition processing, meaning Event-Based Revenue Recognition will not reflect to any G/L posting which belongs to this source ID.  It has the entire cost element group YBPS assigned. For the costs which you want to record but not bill, it must be included in YBPS. But it will have no impact on revenue recognition. Note that there is a sequence for the source IDs. The system always reads from the specific source ID to the general source ID (top-down). Once it finds G/L postings which belong to a source ID, it stops looking to the lower sequence ones. Hence, it is very important that the general one should never come before specific one. The source ID YM0 should never be ahead of any cost source ID. If the system does not find any cost source ID/or postings which belong to the source IDs before it comes to YM0, it will not do any Event-Based Revenue Recognition postings for the costs posted. 

Kindly consider to map relevant condition/GL accounts to a EBRR source(other than ***YM0) if they are relevant for revenue recognition via SSCUI 102530 - "Maintain Settings for Event-Based Revenue Recognition".
Under 'Source' tab, choose related EBRR source, double click 'Assign Cost Elements and Accounts'.
