Receivables SLA sources for Intercompany transactions

Hi,

We are working on creating new Account Rules for Revenue accounting class JLRs, where the condition must be based on Intercompany Flag from the transaction header (RA_CUSTOMER_TRX_ALL - INTERCOMPANY_FLAG).

Tried to identify the Receivables source corresponding to this flag in Manage Sources: Receivables, but I can't find it.

Please let me know if there is a source available or not for the intercompany flag.

If this doesn't exist, then let me know the sources for bellow information from transaction header from UI:

Transaction Source

Transaction Type

Reference

Thank you!
