Thanks for your valuable suggestions Mr. Irfan and Mr.Jurgen.
Actually I've wrongly mentioned it as one material type, the Abap dump is for one material. I'm sorry for that.
I've checked the material along with the functional consultant, the material has
only 2 entries in MB51. One with 101Movement GR for PO with 2 quantities and the other is Goods Issue for 1 quantity of the movement 261.
The Current Stock for the material is 1.
The SELECTION PARAMETER for MC46 is Material No. and Plant.
Note: The Warehouse Management is active.
Please advice..
Thanks & Regards,
Karnan
