How to make change Product allocation time series from ABAP layer

[BODHISATTWA__20]

I have to make some changes to product allocation object from ABAP layer .I was looking for an API    that is released . I found in SAP API hub that we have a BO I_PRODALLOCATIONOBJECTTP_2 that can be accessed by EML .But we are on HANA 2021 I cannot find this BO (Screenshot attached below) .But we could find I_PRODALLOCATIONOBJECTTP which is not released . Neither I could find any BAPI .

https://api.sap.com/bointerface/I_PRODALLOCATIONOBJECTTP_2

 Is  there any BAPI for product allocation Business context that is available or we can use I_PRODALLOCATIONOBJECTTP
