One of the our data load from APO system to BI is failing with dump CALL_FUNCTION_RECIVE_ERROR in BI.
We have noticed in APO system that all data extracted are creating in only on data packet and trying to send in one Idoc. Due to lack Roll memory in APO the tRFC request is failing with a error "Error when recieving answer to a RFC".
We have taken 2 actions.
1) Increased the Buffer size from APO side.
2) Reduce the data selection with plant wise and year wise for the data target.
But still the data extracting from source in a single data packet is huge and why it is loading in 1 package instead of 1000 records per package, as per the settings.
Please let us know what could be the problem.
