Key word 'filter' cannot work as expected when testing Odata Service API in Postman.
Statement below will be generated in case more than 1 filters are added.
https://host-name/sap/API_MATERIAL_STOCK_SRV/A_MatlStkInAcctMod?$filter=Plant eq '1010'&filter=MatlWrhsStkQtyInMatlBaseUnit eq 10473

Reproducing the Issue
Create API call with tool post man and add more than 1 filters
'&' is used instead of 'and' in the statement and this is not valid in Odata Service statement.
Edit the statement and use the key word 'and' if more than 1 filters are used.
/sap/opu/odata/sap/API_MATERIAL_STOCK_SRV/A_MatlStkInAcctMod?$filter=Plant eq '1010' and MatlWrhsStkQtyInMatlBaseUnit eq 10473 and Material eq 'TG11' and StorageLocation eq '101A'
