Availability check - external procurement


I'm looking for a user exit/enhancement where I can change the date that is taken into consideration during an ATP check when creating an order in VA01.

Standard SAP uses the 'planned delivery date' (MARC-PLIFZ in material master) in case of an external procurement, but I need to change this to the 'total replenishment lead time' (MARC-WZEIT).

Does anyone have an idea which user-exit or enhancement is suitable to achieve this?

Thanks you for your help.

Best regards,

    You can try with the following;

    EXIT_SAPLATPC_001 (include LXATPU01) and EXIT_SAPLATPC_002 (LXATPU02) in the enhancement ATP00001 (program SAPLXATP)
