Message no. MG144

Dear SAP experts,

I am facing one error while creating or extending any material.

Message no. is MG144 (procurement type is required). After I do the entry system is again asking me the same . i.e, system is going in loop.

I have checked the configuration and it is O.K as external Purchase = 2 and internal purchase order as 0.

Please help.

Regards
