hi could someone who has tested this thoroughly tell me the difference between /sapapo/ctmtestdatacreate and BAPI_STSRVAPS_SAVEMULTI2 for creating stocks in APO. What happens when it is done through CIF. (mb1c, mvmt type 561). no where its evident whether this is adding to the stock or overwriting the current stock. sorry my sandbox is not working at the time of sending this mail. I normally used mb1c in the past to be safe. learnt abt these fm's recently.
