Hi Shahzad,
Thanks for your answer.
The tolerance setting of availability is ok according to the FM fonctional consultant.
I'm searching function or programs called to update FM, any idea ?
These are the Badi called during the update
MD_STOCK_TRANSFER
ME_ACTV_CANCEL_PO
ME_CCP_ACTIVE_CHECK
ME_CHECK_ALL_ITEMS
ME_COMMITMENT_STO_CH
ME_COMMITMNT_PARKING
ME_DEFINE_CALCTYPE
ME_GUI_PO_CUST
ME_HOLD_PO
ME_PO_PRICING
ME_PO_PRICING_CUST
ME_PO_SC_SRV
ME_TAX_FROM_ADDRESS
ME_TRIGGER_ATP
I've implemented the BAdi ME_COMMTMNT_PO_REL_C to force the parameter "is_relevant" when the purchase order is held but it's not better.
