why official document numbering is required in MIRO?

[SoumeyaG]

Hello all,

Self-billing has been activated for some vendors /french companies in our system. The process is working according to expectations, using official numbering of invoices, according to french regulation. 

However, when a vendor with active official numbering (LFM2-XERSY populated) is used for a company with ERS EU range populated (T001Z-PAVAL), even if there is no ERS agreement for the vendor within this company, the system generates an error (8A827) during MIRO, requiring us to manage a range for official documents for the vendor/company (in transaction J1AB).

Is this normal ? How can we avoid this ? Especially this is causing issues to business :

• need to manage unneeded ranges for combinations of vendor/company in J1AB
• vendor reference set, by business, during MIRO in RBKP-XBLNR, is replaced by official numbering, while the invoice is not an ERS one and vendor reference is lost
• in the futur, if an ERS agreement is signed for the vendor / plant of the company, ERS invoices will start at an advanced number, confusing the vendor and without be sure about legal validity of this numbering. 

Please advice.

PS: we are in ECC6.

##MIRO; RBKP-XBLNR; ##OfficialNumberin

Thank you in advance

Best regards
