1. I confirm BOOTS organization in EOLP is FMP but to check your program you can use FPC on DUE1. Also it is critical to ensure the program is still working for FMK organization (BBGR UK case)
2. For BBGR UK (FMK organization) in fact we have 2 cases:
standard sales order issue corresponding to EOLP bulk cases and sent to BOOTS needing to be considered as consumptions
dedicated inventory transaction types corresponding to Rx issues and return from production linked to the account alias ISSUE_TO_LAB_ACT_ALIAS and LAB_RTN_ACT_ALIAS set up in lookup INVENT_VMI_CONSUMPTION_EXTRACT LOOKUPS.
For EOLP (FMP organization), we will consider only the sales order issue linked to orders having the order type set up in the DFF LAB_OM_TRANSACTION_TYPE of the lookup INVENT_VMI_CONSUMPTION_EXTRACT LOOKUPS. As you mention, these ones correspond to RX issues in EOLP context with reservation and sales order creation implemented.
3. I will try to implement set up on IUE1 and IUE4 within today and keep you posted.
Let me know shall you need any further information to go on in development.
