Iam using material Bom for header material
Below header at level 1 there is material A which is made phantom in BOM of header material
At level 2 below A material X is available.
Iam changing component X with ROH material type with other component Y with ROH material type.
After that MRP run is done.
PR created for X is not firmed but system is not deleting it and in CO46 iam getting MAterial X instead of material Y.
When i remove phantom status of material A in BOM of header material then after MRP run system is removing material X and put material Y ( Once changes are made in BOM of A)
Planning file entry for material A contains explode bom tick in both cases.
Please guide .
