how to provide a single document with BAPI_MATPHYSINV_COUNT or with similar FM?
when i trying to do it returns me an error.
'Item 001 requires exactly 2 serial numbers for the asset'

Just provide two records in the table parameter SERIALNUMBERS for the item with quantity 2.

if I provided 2 serial numbers:
"Item 001 requires exactly 4 serial numbers for the asset."
I think the problem is inside the "items" parameter, it only has one entry when there should be two.
But if they exist, is there another FM that will allow me to play only one record?
Or do I need to add something else to the other parameters 'BAPI_MATPHYSINV_COUNT'
