Error in loading 0BPARTNER ATTR & TEXT

Hello Experts,

We have 0BPARTNER_ATTR and TEXT in our production process chain. We were successfully loading for the last few days. Suddenly, last night, we got the error for both ATTR and TEXT laoding with the following message:

Data target '0GN_BP ' removed from list of loadable targets; not loadable RSM 33

Data target '0GN_BP ' is not active or is incorrect; no loading allowed RSM 36

Could you please guide on what would have gobe wrong. We did not touch the IO or transfer structure" and the data target is 0BPARTNER infoobject and the error message says "0GN_BP".

Any help is appreciated.

Regards

Raj
