Multi-co Inter-co can not remit to a specific supplier AP-Auto_load supplier set as INTERCO

This is a multi-co environment (5 active companies). Inter-co drop-ship is viable for all companies.
GO LIVE was Jan 2023… started working here 4-20
AP Open Load was processed 12-31 with entries resulting as POSTED (AP Invc Tracker)
in that a consultant managed the loading… unsure if AP OPEN LOAD or DMT was used?!
A particular inter-co supplier IC06 with activity to only 2 other companies 03 and 08
Attempt REMITANCE - appropriate Invoices are listed
EPICOR message ~ UNPOSTED INVOICES

REMITTANCE processing for all other inter-co relationships is NOT problematic
Ran a BAQ - dumped Inter-co Supplier data for all data-fields
Intercompany and Intercompany-trader set as TRUE ! !

Have yet to deep-dive into INVOICE’s …but that would be the next step, unless
additional insight (pun intended) can be garnered from the forum

THANSK in advance !

SOLUTION: While the GL CONTROL - EXTERNAL COMPANY records and specified GL Accounts were correct within the primary company, the associated company’s were lacking the correct combination of GL Accounts as the segment content was not properly aligned/matching the primary company. The External Company - GL CONTROL data-bridge across companies was disconnected!
Co-CC had correct set-up for Co- FF
but within FF… intended GL Account / a segment was corrupt/mis-match
while the account in FF was a valid account, but mis-aligned to CC intercompany
Co-EE had correct set-up for Co- FF
but within FF… intended GL Account / a segment was corrupt/mis-match
while the account in FF was a valid account, but mis-aligned to EE intercompany
