ODATA Service Error : GetEntity(READ) operation : Mapping can cause runtime data loss

sanjana_lingras — Mon, 01 Jun 2020 11:55:44 GMT

Hi Experts,

I am facing issue while generating Odata service for Material Read interface. I have developed custom RFC to read material data based on material number as a key. RFC has 31 Export parameters and I have implemented GetEntity(Read) method.

I am able to successfully import the RFC in ODATA service but while trying to Map Data source for GetEntity(Read) , I am facing error Mapping between parameters can cause data loss runtime.

Can you please let me know what could be wrong? I have attached error screenshot.capturenew.jpg

It is a warning message only. However, please check the length of the mapping fields. Example MATNR ( that defined in the table ) against that defined in your ODATA property. It should be same.

Regards,

Venkat

No I have imported from RFC and data types are same as table.

Its not warning, while generating service its giving error.

Hi Sanjana

Please Make changes to properties Ezmatnr1..to. Ezmatnr5 - change the max length from 10 to 18.

Also, please show the table strcture of E_ZSACCO1 to 5.
