ATP check - behaviour different from standard requested

Hello my friends Gurus,

Happy new year to everybody.

I understand that ATP calculation in sales document is different in case of the procurement type in MRP2 view is F (external procurement) or E (in-house production). The system takes into consideration respectively GR times (Purchasing and MRP2) + Planned Delivery Time (MRP2) for "F" materials and GR times (Purchasing and MRP2) + Total Replesnishment Lead Time (MRP3) for "E" materials.

For business reasons (as for instance transfer order between plants, specific program ...) we can't change the procurement type in Plant for F materials.

So the question is quite simple : is there a way for influencing the ATP check and calculation by passing to the system others parameters of dates, as for instance Planning Time fence or Total Replesnishment Lead Time ? Have you already met such demand and how do you manage this ?

Of course we could go through (I suppose) an user-exit but we appreciate customizing proposals.

ps : parameters in availability check control in customizing : all is flagged in Stocks box except "Incl. restricted-use stock", all in flagged into In/Outward movements box except "Incl. ship notification", Check without RLT is not flagged, rule A in Receipts in past.

Thanks in advance for your feedbacks, it will be appreciated.

    Since the Business requirement is only for certain process, with the standard configuration, it is not possible to achieve this requirement.  You may however, try with Function Module AVAILABILITY_CHECK_CONTROLLER
