InfoPackage delta load error, but repeat successfully
we are facing a strange behavior when executing a infopackage.
The datasource is created via RSO2 using delta = AIMD. We use a programm to select the data and insert it in the deltaqueue.
So the data is already in the queue when we start the infopackage. We only using a dummy function module to trigger the transfer of the data.
So the problem is:
When we start a delta load, it brings up an error (RSM340 - Error in Sourcesystem), but when we make a repair or execute the infopackage again, (immediately or a few minutes later) the load works.
We have checked everything, joblogs, idocs, trfc, authorizations and everything is ok. All jobs are being executed in the sourcesystem correctly and the idoc´s are sent back to the BW.
We are on a SAP BW 7.31 SP7 system.
Does anyone has an idea, where to look or whats could go wrong?
