Hi rina04…
I have the same case with yours…in other case…the item cannot be import with excel…may be it work and all item that we import is inserted in table inventtablemodule. but its not in inventtable…so when we search that item in item detile…so we have to delete that item in inventtablemodule first then we re input manually in item details
its just my experience…hehehhe…I hope its help.
