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

[sanjana_lingras]

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

Hi

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
